Hi guys,
2 weeks ago I published my new paid app on Google Play, and first couple of days I go 25 downloads a day, but last days, I get only 1, 2 or even no download a day. App was 3. in Top selling news in education, now it fell to lower posts. A lot of people like the app, desing and everything. I was putting a lot of work and time in the app, I was happy first days, but now I'm disappointed. I know that downloads will naturaly fall in time, but this? So what am I doing wrong? Do you have any tips to promote the app more?
I discovered this site appszoom.com, you can buy there review for 100$ and they do it in 48 hours and you have your review for 4 days on their homepage. What do you think of that?
Also, what price should I set it on? It was on 0,99$, but I think it's too low and if I set it on 1.99$ people say that it's too expensive...
If you buy my app, coud you please write some nice review? People that like it don't write reviews and then they are just haters, that write just for the fun...
App is called Science in Pocket, just search "Science in Pocket Serpentcorp". I have lite version without ads too.
Thanks for any advice!

How are you marketing your app right now?
I'd advice against spending $100 on stuff like reviews etc unless you know exactly what you're doing, and that you have a killer app. Try free things first and see if you can get something going that way first, and save your money until you know more about where to spend them.

how to promote my android app for free???
I guess you can find many promotion methods after you install an app from Google Play.
Splash window,
Push notification,
App recommendation inside an app.
Corporate with other developers and promote apps for each other.
...
Well, at least the first three promotion methods can be found in most of the apps from Google Play.
But who knows more promotion methods?
You may install swably and share your apps in there, its community where dev and customer share thoughts about lots of app

As previously stated, Swably is a free way to promote & share apps. That's probably your best bet.

can you access Facebook on your phone?
subscribe to getjar and publish your app. or publish your app on Amazon appstore....
OR
Go To This Site and Publish [media.droidtweak. com / android-app-marketing] (Copy and paste it remove spaces, m a new user so i cant post outsider links, m jus trying to help, sorry moderators)
OR
Before you make any sort of promotional effort, you need to do the following:
1) Make sure you have a good rating. Get 10 friends to give you 5-stars. Nobody wants to download an unrated app (or even one with less than 5 ratings).
2) Add a video on the app store. It doesn't need to be pro, just something that gives a good indication of what your app does.
3) Make sure your screenshots are good and your description is accurate. The first sentence is the most important for describing what the app does.
After it's on the store (free version):
1) Post in forums
2) Submit it to review websites
3) Write up a press release (catchy headline, what your app does, why is it better - have a good angle) and send it to every news / tech / related website you can find. Who knows, 1 or 2 websites out of the 100s might write something about you, which can get you 100s of downloads. It's worth the hours it takes to do this. Also, use some Mail Merge software to make it personal (as simple as "Hi [name]").
4) Find influential twitter users that you think would use your app. Send them a message - dont harass them though. Be sincere. If they like it and they haven't tweeted about it, ask them to.

New android app - need exposure
Hi everyone,
I'm a noob here (hopefully I'm not violating any rules) and was hoping to post one of my android apps here to help it gain some traction. My 11 year old son worked with me on this app, I would just like to keep him motivated by seeing some success.
Lately with the way the android market has become saturated, it has been very tough to get your app discovered.
I only do this as a hobby on the side. I have only developed games, they are all pretty simple games, no 3D or anything like that.
I recently released a dice game app (variation of Yahtzee), That I think some people would like.
It has some online challenge features with scoreloop, and an extra game mode.
My downloads to date are pretty poor, and was hoping to gain some exposure.
here is the link on the google play store:
play.google.com/store/ apps/details?id=com.anndconsulting.yahtzeecrag
I have a free (ad supported) and paid version released.
developer ID is ANND Consulting Games
Thanks for the help
Please let me know , if there is a better way of doing this, and I apologize in advance if I have violated and rules here.
When I was trying different methods to promote my app, I kinda noted it down. Here is brief about what I did:
http://obscurant1st.biz/blog/how-to-promote-android-app/
1. Never use push notifications aka push it to people's notification centers. People will perceive it as spam, and never download it. Ever.
2. Contact several Android news sites, and tip them that your *special* app is available. With special, i mean, really special. Don't even do it if it's a fart app or a stupid and useless app. You don't deserve the attention.
3. XDA. Publish it in the app section. People will find it and download it. People will use it if it's any good, or people will complain if it's ****; and you'll deserve it.
Bottom line: Build it, and they will come. Exploit the system in a bad way and you'll go nowhere. Don't piss people off with annoying ads.
From my very recent experience, getting a review on a major website with tons of viewers will get you a ton of attention. Websites like android police and android central have a ton of views per day.
My usual promotions were to post on forums. If you were lucky and people paid attention to your app, they'd download it. The more downloads you get, the higher chances of it showing up on Top New apps or just Top Apps. Once you get on that list, its when the app will finally take off. Its took 2.5 weeks for my live wallpaper to get to top 10 new paid live wallpapers and top 10 new free live wallpaper. The Top Paid live wallpaper is easy to get on as only a few purchases will qualify the app.
Anyway, back to my point about the review. My app was doing ok and there was a consistent downloads per day then it started to decline a little. But all of a sudden, my google wallets account exploded with purchases and my free version with admob banners, the requests and impressions exploded. I was shocked and had no idea what was going on. Then, a quick google of my app, revealed that android police decided to give my app a review. i was shocked. I never asked them to review it, so it was pretty much free publicity. If you look at the little graph on the right side of my app, you'll see how it was starting to decline, then all of a sudden, it shot up.

Here's the review on my app.
http://www.androidpolice.com/2013/0...e-way-to-track-your-lithium-ion-expenditures/
Main points:
1. Post on forums
2. Get a review done.
Side note, I've never seen a good app not get downloads. All good apps will get tons of downloads.

There are lots of ways. Requesting a review for your app is one of the easiest ways.

In other words: what you say about yourself, is advertising. What others say about you, it's public relations - much more effective way of promotion, but much much more complicated, too.
If Any on suggest me.
My app is going better download approx 2000+/day.But compare to review is very low.
Please suggest me how to increase our app review in Google Play Section.
What's the app, read the reviews people are leaving and see if you can do what they are asking.

I believe your low review rate is caused by the fact that an adult person sees your app maybe once and then it's all in the hands of children. You should be glad that your app has so many downloads despite low review count! :good:
You can add something like "Review my app" in the menu of your app.

Are you doing anything to entice people to rate the app?
It's a free app, which probably means it's like a throw away app for most. Unless you get people engaged to rate the app, you probably won't get more than the rate you currently get.
Would you be able to ask parents to provide their email address, and then you could follow up with them a couple of weeks later and ask for a review if they have any comments to share?
After three weeks with my game in the store, I got most of my reviews from the following sources:
1) Friends
2) Fellow developers
- this is probably the most important, because they will write a good review
- good way to get a review is to review somebody's app first and then message them (with some more feedback preferably) - I think I got like 15 reviews this way, works best in smaller communities
Friends and family is like cheating.. i don't do it but i think everyone does
Have you tried push notifications?

You can increase app review by sending a push message on a particular event to users with request to write a review .Also if your app is a game you can ask for review to unlock next levels.

I tried asking them to put review when my app finished something useful for them.
the best way would be push notification in the app, ask people to review on social netoworks facebook twitter, but the best ones will come from customers
You should engage people in their discussions........
Using Social Networks helps.
If you have good download rate try ask your customers to write review for you, or maybe try to implement that option into your app.
I will give brilliant and honest reviews. If you like please let me know. You know I have some app and reviews with 5 star rating helps me lot to increase my business!!!!:fingers-crossed::fingers-crossed::fingers-crossed:
Lure them
I think one thing you can do is to try and lure the user to write a review. You can do this by giving out bonus features on every review/rating. If yours is an educational app then maybe certain features will open up only with a review.
If you develop in Java consider using AppRater script - it gives a very simple way of integrating rate request into your app
Getting reviews.

Does your app solicit reviews within itself after being opened a few times. I have a database item that records how many times the app has been opened and prompts the user nicely for a review after the 3rd and 7th time opening the app.
Now my question to you is... HOW did you get 2000+/day downloads? I'm nowhere near that. However I do have about 10 reviews for every 100 installs.
2000 + downloads per day?
Its better then nice.
My apps have near by 100+ downloads per day and I don't know why...
It's was very hard and almost impossible if you don't have at least a small marketing budget. I am making this thread to help developers learn.
I want to stress that all my marketing was free. I didn't use paid advertisement.
Deciding what I am going to make
1) I decided to make a platform game that had very simple controls, anyone can understand how to play it without instructions.
2) I decided to use some cartoon images that, almost all I made myself. There is no some "Complicated graphics".
3) I made the game easy enough so that a gamer can play it without instructions.
Before Launch
1) After I finished the game I didn't release it to the google play store , that would equal a fail. I opened a small community in Google+ and collected some people that want to hear when I release the game to production.
2) I posted on facebook groups screenshots about my game that going to be published. I did it in 5-6 groups and I spend on it 3 days.
3) I went to some games forums and also a create a post and trying to make people waiting for this game to be published.
Launch
1) Launched my app on Google Play , posted on facebook and on Google+ that its finally arrived. And here comes the numbers:
After one week my app got more than 10,000 installs!
And now my game has 46,000 downloads at Google Play!
And I am still fighting to get more downloads. Hopefully I can reach higher but for last couple of days the downloads just decreasing Any questions ask away.

I don't think you got the downloads for the reason you think. I am unsure what you did, but almost 800 ratings is good.

And thanks for replaying
Pretty interesting read, thanks!
Do you have a facebook page or something where people can follow you as a developer? I'm not sure if I should do that for the future.
4 days ago I published my first Android App. I prepared my release fairly well, I've read a lot about marketing apps.
- I've posted my app on forums where I'm active, inclusive a niche forum for the app.
- I've posted it on my personal facebook and tumblr.
- I've made a pretty good YouTube video for it.
- I've send it to over 30 review sites.
The reviews I've received are all very good, but I'm still struggling to get downloads. I'm still at 50-100 and I've done the best promoting I could.
Any tips?

Look at my first comment. Publish your game in facebook groups and forums and try to get people knowing about your game, If they like it they will share it with their friends and you will get more downloads.
BTW I saw your game. Its looks very nice Keep updating this game.
This is cool!
hi , cool game you have there

Juste to be more helpful what's the list of forum where you have annonce jour game,
Thinks
From my own experience I can say, that it's very hard to find the right formula. There are so many variables and sometimes one method will work for specific app, sometimes not. But I agree that social factor has the best influence in downloads. The more people see, hear about your app - the more likely they will tell their friends and etc.
Thanks for the information really helpful, I will open a community in G+ right now for my current project.
Good luck with your platformer
Hi guys!
Do you know any web sites who write real free reviews about android apps? Not payed reviews, not review exchange, but just honest review of my app, its good and bad sides.
I tried submitting my app - play.google.com/store/apps/details?id=com.triladroid.gps to all websites, posted in this topic - forum.xda-developers.com/showthread.php?t=2800333
And from most of them I got an e-mail with suggestions to pay money to get positive review and featuring on their websites. From now on, I just starting to think that it is almost impossible for a developer to get a free honest review on some website.
Maybe some of you know websites who are interested in writing real review for free? Maybe your app was even reviewed on some website?
I will appreciate if you share your experience with me.

The question was about free real reviews. What you are proposing is to make a payment for sending proposals to review one's app and then make other payments for those reviews. Maybe your service is really great and saves a lot of time, but one still have to make a great investment.
Unfortunately, i don't know of any site which will make a free real review. There are lots of sites which will post your review for free, but they lack audience who will read it. Others make only paid reviews.
Hi all,
I have low budget for the marking of my new game that i will publish soon
I have only $200 , is that amount will effect or i will just spend for nothing ?
and how i can use them ?
Thanks
It would be very easy to throw that money away. It won't do a lot, all told. Focus instead on the app, encouraging people to review it positively, managing bad reviews, building up a good relationship with an initially small number of users so that they'll tell their mates and build your numbers up. Talk to people for whom your app solves a problem. They don't exist? Well, there's your problem and $200 of marketing won't help

Ryan has an important point: actually, adwords, facebook ads, *can* bring some result but at a too much heavy cost. I have tried them and my cost per install was like $5 to $10, for free apps...
Prompting users to review your app in your app works, but do it at moments when they achieve something positive with your app, like attaining a certain level in a game. Building a relationship is a key, i can't agree more to that
$200 is a low budget.
Try first the all free methods we all know are aware off (mailing, asking parents and friends to download and promote the app, posts on forums and so on).
Also try to exchange reviews with other developers (I'm always willing to do it, for instance).
And if your really want to boost the number of downloads of your games in order to look more attractive for users visiting your Google Play page, you can buy incentive installs from tapjoy (0.10 / install will give you up to 2,000 downloads (but I don't think it worth the effort, as vast majority will remove your app right after they get their rewards).
Here are some useful methods to increase downloads for consumer mobile apps:
• Application name-is unique
• Keywords-including related keywords, but be careful - don’t stuff every keyword into your app
• Make Facebook or Twitter page for your app and write story of your game there to attract every users
• Description. Your description is clearly the value of your App
Best of luck in your app business.
