SpendLock adds deliberate friction at the moment of temptation — not a report card the morning after.
Free during beta · iOS TestFlight · No bank login required
Budget apps show beautiful charts of damage already done. They don't stop you at 11 PM when you're about to order your third delivery this week.
Every app on the market shows you what you spent. The habit loop is already complete by then.
In-the-moment decisions override rational intentions. You need environmental design, not more discipline.
People understand budgeting. What they lack is a circuit-breaker at the exact moment temptation strikes.
SpendLock doesn't connect to your bank. It works by inserting a deliberate pause between impulse and action.
Choose a category and a time window or spend limit. "No food delivery after 9 PM" or "Max $100/week on UberEats."
When you try to break a rule, a lock screen appears with a reflection prompt: "What are you buying and why?"
A mandatory 5–15 minute timer runs. Most impulses die before it expires. That's the whole point.
Every day you honor your rule, your streak grows. Break it, and you start over. Simple. Effective.
See how much you avoided spending, when your trigger patterns hit, and where your discipline is paying off.
