The pro upgrade was not free, an no, I don’t get paid several times for the work I did once where I didn’t even complete the task. My point was that the app needs to get to a certain level before you start considering this radical change in business model, or, frankly, it is just going to piss off people who paid for a pro version expecting more already.
While the app has its graces (for me, the export functionality and a LACK of subscription model), if you plan turning it into a subscription service where I have to bleed money every month, frankly there needs to be a substantial level up in terms of reliability, functionality and pace of development.
The aforementioned example with the lack of an exercise log view is a prime example of this.
