TouchRetouch has switched to a subscription model. The older app cannot be downloaded by new users. The new app allows you to restore your old purchase and sets you to a core plan, where all the old features from that app still work. But, new features will require a sub.

The devs are also giving a 3 months promo from play store reviews and 50% off to old users for the yearly sub.

It could’ve been worse, like not honoring your previous purchase. But, this is ok.
