Today I'm launching Lumi - an automatic expense tracker for iPhone.
I quit every budgeting app I tried for one reason: keeping it updated was too much work. So I built Lumi around a single idea — log any expense in ~3 seconds.
Say it out loud, scan a receipt, auto-import from Apple Pay, or just double-tap the back of your phone. No bank login, your data stays private. Plus an AI month-end forecast, 150+ currencies, and Family Sharing.
Free to use, Premium from $1.99/month. I'm solo on this and would love your feedback.

The “3-second logging” constraint is probably more important than the extra features.
Curious whether users actually keep logging because it’s faster, or whether another part of the experience is what makes them come back.
Actually, you just need to wait those 3 seconds for Wallet to activate, and then make a single click to select the appropriate expense category.
