We are looking for a money-friendly way to beta-test our mobile app puzzle game before launching it.
Based on my own experience building indie games I'd recommend these Reddit and Slack channels for beta testing:
Reddit: https://www.reddit.com/r/AlphaAndBetaUsers https://www.reddit.com/r/playmygame https://www.reddit.com/r/indiegameswap/ https://www.reddit.com/r/freegames
Slack: https://www.hamsterpad.com/chat/hashtaggaming https://www.hamsterpad.com/chat/gamedevelopment https://www.hamsterpad.com/chat/indie-game-devs
Also, just give it to your friends and family and you can record their interactions with it using something like: https://www.lookback.io/
Finally, some paid options include: https://www.usertesting.com http://ubertesters.com/ https://betafamily.com/
If you want to discuss how best to design customer interviews / questionnaires for your specific app, to assess what you need to change, what to keep, etc. feel free to send me a message,
best,
Lee
