Good stuff. This actually solves a minor, but frequent real problem. A couple of things. This needs a way to audit the downloads, i.e. to be able to see that the link was accessed by these IPs at this time (mind the time zones!). And perhaps also log and show cookies and user-agent. Secondly, what's up with SignUp and Login? Just let people download the app and give them N uploads per month for free. Or just M lifetime uploads for free. Then ask to top up the credit, pay for a month or perhaps, shockingly, get a monthly subscription. All this signing up and logging in just muddles things and fits the app like a square peg in a round hole.
