IronLog
A workout log that needs no signal: 409 exercises, automatic personal records, and a rest timer that keeps counting when the phone locks.

The problem
Basement gyms have no signal, and most workout apps stop working the moment they lose it.
How itworks
Plan
A routine for each day, built from a library of 409 exercises.
Log
Weight and reps for every set, ticked off as you go. A new personal record is spotted on its own; there's nothing to work out.
Rest
The rest timer keeps counting when the phone locks, and tells you when it's time.
Keep
Every set stays on the phone. One tap exports the lot as a file. Nothing is ever sent anywhere.

Your turn
Describe the idea everyone told you was impossible.
A few sentences is enough. Tell me what it should do, who it's for and which range you're in. I'll tell you honestly whether I can build it, and how.
