Looking for Android apps made by IH to promote for free

I am building a community of beta testers for Android apps for quite a while already and I have a good use case for a round of free promotions that I can offer to IH devs.

We have an Android app that is installed on 19k devices, FB group with 3k members and 1k followers on Twitter plus some other sources like Website and Telegram channel.
Normally, we publish apps submitted by devs themselves or doing paid promotions or just publishing popular apps by ourselves.

Currently, I am refining some new ideas for the project to experiment with and I am curious to see if there is any demand behind them.
You can check for "TestingCatalog" to get a better idea as well.

What I will do:

• I will add your app to our catalog of Android apps available for beta testing.
• I will share it on our social channels.

What are the requirements:

• The app must be in English and available globally.
• The app must have a beta release track on Google Play or it must be newly released (less then 5k installs).
• The app must be available on Google Play or it can be also a custom pre-release beta form with proper description.

What you will get:

• Normally we guarantee 50-100 link clicks for our paid promotions within one or two weeks time range.
• Our audience mostly consists of people who like trying new things and potentially can leave feedback. We don't incentives our community members so all further conversions depend on your app and your offer (app installs, feedback reports).
• Our audience is 70% male and global with US and India being our top geo-locations.

Feel free to drop a link in comments and please add some description there about what do you expect from testers to do (any specific feedback or if you have promo codes to offer). Any questions are welcome too!
