DealUp

DealUp is an iPhone app for social challenges with friends, proof, and follow-through. Instead of keeping goals private in a notes app or habit tracker, you turn them into visible challenges with rules, stakes, progress, and receipts that other people can actually see.

You can create a challenge around things like being on time, reducing screen time, saving money, cutting sugar, finishing workouts, or sticking to a shared plan with friends. Each challenge can define what counts as success, what proof should be posted, and what happens if someone does not follow through. That makes the commitment harder to ignore and much easier for a group to rally around.

DealUp also has public challenge pages on the web so new users can understand the format before installing. People can browse real examples, see how challenge rules are structured, and get the idea quickly without needing an account first. That makes the product easier to share and easier to discover.

For people who are tired of private reminders that are too easy to dismiss, DealUp offers a more social and accountable way to follow through.
