Pricing
Free covers the whole point of the app. Premium removes two limits, when you want them gone.
Free
1 active promise at a time · 30-day history · all commitment-enforcement features · lockouts always clear for free, on a timer — nothing to buy, ever.
Premium — $39.99 lifetime
Unlimited active promises · complete lifetime history · full contribution graph · lifetime statistics · once, forever, no renewal.
See the FAQ for what happens if you break a promise, or Guides for a walkthrough of making one.
