Hi, everyone! We are looking for beta testers for our startup app. App is available on iOS only, so it?s exclusive on iPhones. No hard feelings, Android users ? you?ll be next on our list. Anyway, this is a location- and time-limited and (very) social app, so you should test it in specific conditions. Basically, you are online for a short time and visible only within a few kilometers/miles from your location (don?t worry, you can go online again ? it?s unlimited). However, this means that it?s probably the safest bet to invite your friends to try it out as well. And what do you get in return? Well, everyone who joins as beta tester (including your friends) will be marked as a "power user". This way, if app goes viral, you will have all the future paid features of our app ? for free! And, above all, we believe that you can be a part of something new and great ? but we?ll let you be the judge of that. Finally, I?ll send you more detailed instructions after you accept this offer. I hope we?ll talk soon!
