I built an app where you bet on yourself to build good habits.
LastOne = Accountability through competition.
The concept: → 100 people join a "gym daily" challenge → Everyone puts in $50 → Check in with proof every day → Miss a day? Eliminated. → Last one standing wins $4,000
Why it's different than every other habit app:
Real money on the line (not just points)
Public eliminations (social pressure works)
Competition (winning > self-improvement for most people)
Viral by design ("I won $800 going to the gym" posts itself)
1,000 of these challenges running daily = a potential of $1M+ in revenue.
What habit would YOU bet on yourself to build?
