Extremely predatory practices. They automatically put you into a subscription before you even get to use the app. They say it's I free trial but it auto bill your payment method after on 7 days. EDIT: in response to the dev. It is preditory because of the "free trial" model that you've chosen to employ. You're relying on people to forget or not even know that they have to manually cancel a subscription. If you actually want people to have a free trial experience lock out features after 7 days

We choose the Free Trial option as it allows a user to try before buying, the market does not charge you during the trial and you 100% control the trial and what happens after the trial. If you have any functional questions give us a shout at Thank you for looking.

Purchased this app several years ago and really liked it but then replaced my phone and found out the greedy brain dead morons had switched it to subscription base! As expected their verify previous purchase system is broken, did not work. For obvious greedy reasons.

Andrew - we did not switch you to a subscription. You just missed an update which would have made reinstalling your App on your new device seamless. Not a problem at all. All you need to do is contact us at and we will get you back up and working.
