We need beta testers for our new app "Field Recorder". It is the most professional audio recorder making the best out of the internal hardware. We offer a 40% reduced price during the introductory phase, and the direct contact to the developer to suggest new features or to criticize old ones. But as you still pay you will have the full rights as every customer at Google Play. That is, 1) the 15 minute return period, 2) the regular version of the app, 3) a life-long license without additional fees, and 4) of course we won't force you to give feedback. What do you think?
