Also I know that everyone does it, but the “free trial but we’ll charge you even if you don’t use the app and just forgot to cancel” is something that I really dislike. Maybe it’s an AppStore limitation but I rather do a trial and only pay if I actually use it, not if I forgot to cancel.
Lastly, maybe it’s after the paywall, but not everyone knows what all the routine names mean, if I have to google it, it’s something I expect the app to include. (A diagram / video of how to do it the right way)
Other than that, looks exciting and a really nice take on this topic.
