Good up to a point

I love that it gives you a schedule of sets to do, and you can set reminders. Its nice that there are many different kinds of push-up described, but then the app doesnt relate them to the programme! Lets say I can only do a few push-ups on my knees, or inclined. How do I work up to more difficult ones? Do I do the whole programme on my knees and then start again once I reach 100 of that type? Do I mix them up? It gives no indication.

Ive been doing the programme with "standard" push-ups. Im just starting, and I got stuck on day 3 of week one. I can do all but the final set—which I have to break up. Is it okay that I stop and rest as long as I finish them? Should I switch to inclined or knee push-ups to finish? It doesnt say. Ive decided to keep doing day 3 until I can do it right. Is that the right way to go about it? It doesnt say. If I pause for a rest in the middle of my final set, but ultimately do them all, should I move on?

I guess its good that you can change the reps manually, but I would prefer it if you could just turn the whole difficulty up or down. If I reduce one set of reps, shouldnt that affect the rest of the programme? I dont want to have to change the numbers for 5 sets x 18 days. I got the app to make things simple, so I really want an app that knows more than I do and will just boss me around like a trainer.

I was really looking for an app that was like Couch to 5K—one that acted as a coach and took the guesswork away. I see this getting there. I hope it will.

Also, tell me why I should pay to upgrade! Because I will if theres a reason! But I wont if you wont tell me why!

Also, the voice is a little weird.
