Pick a dare
Smoke-free, a dry month, 10 minutes of meditation, football after school — one tap and it’s set. Or write your own: any goal you can count works.
Private challenges between friends
Pick a dare, send the link and prove it every day with a photo your friends verify. Fake it and they call it out. Lying to an app is easy. Lying to your friends isn’t.
Ten seconds and you are on the list.
The essentials
Smoke-free, a dry month, 10 minutes of meditation, football after school — one tap and it’s set. Or write your own: any goal you can count works.
The dare starts with its invite link ready to copy. Private, valid for 7 days, and only people you approve get in — even if the link travels.
Snap the proof and your friends verify it — or call it out with “Nice try”. The leaderboard moves live, and whoever’s behind gets a nudge.

Everyone has excuses: “I’m tired”, “It’s raining”, “Tomorrow”, “I’ll start Monday”. Your friends won’t let you. Snap the proof, your friends check it every single day, and the streak keeps growing. Photos don’t lie. No more excuses — I dare you.
Today's proof
Every goal closes with a photo taken on the spot — no gallery — and it only counts once your friends confirm it.

Guided tour
Swipe through the real screens: pick a dare, climb the leaderboard, get your proof verified — or called out — and talk it all through in the chat.
Built to last
Everything a challenge needs to stick — and nothing that turns it into a social network.
Proof is snapped on the spot — no camera roll. Friends tap Verify, or call it out with Nice try. If most of the crew isn’t buying it, the day doesn’t count.
Miss a day and the streak really resets. The leaderboard updates live, the crew map shows who did what each day, and one tap nudges whoever’s behind.
A reminder before the day ends, with the hours left and who has already closed. And an alert the second a friend finishes first.
Check-ins, proofs and streaks drop into the chat as cards. React, send photos and voice notes, and see who’s typing.
Quick comparison
Other apps trust your word — or charge you so their staff can check. Here your friends do the checking, and everything else stays out of the way.

Questions
Yes, by construction. There are no open profiles and no discovery. A challenge only exists for people its creator approves, and that rule is enforced by row-level security in the database itself, not just by the app. The only public surface is the feed of finished challenges — opt-in, per post, never with photos or day-to-day progress. Data lives in Frankfurt, under GDPR.
IDarU is free: unlimited challenges, unlimited friends, streaks and trophies included. The app shows a discreet ad banner — and some extras, like messages beyond the daily chat limit, unlock by watching a short ad, always your choice. In the EU, personalized ads only run with your explicit consent.
Each link carries a random 143-bit token, expires after 7 days and can be revoked at any time. Even with a valid link, nobody enters a challenge until the creator approves them, a leaked link only lets someone ask.
Absolutely. Solo challenges are a first-class mode: you race against yesterday's you, keep streaks, earn trophies and get motivational notifications tuned for solo mode.
With proof your friends verify. When you log the day you add a proof — a photo taken on the spot, a timer, a screenshot from the app that tracks it, or an honest check-in for things you can’t photograph. Friends tap Verify or “Nice try”; if most of them aren’t buying it, the day doesn’t count and the streak is recalculated. The creator can switch proof off for a challenge, and then it’s the honor system.
In the app: Profile, then Account, then Delete account. Deletion is immediate and irreversible, challenges you created, progress, streaks, trophies and your login are all removed. You can also request deletion by email at privacy@idaru.app.
Yes, but it's quick: email and done. No phone number, no importing contacts. The account only exists to keep your challenges and streaks across devices.
Proof is on by default; the creator decides when setting up the challenge. Photos are taken on the spot (nothing from the camera roll) and friends have 48 hours to verify them or call them out. Called out? You can retake it the same day. Photos only live inside the challenge and are deleted when it ends.
Portuguese, English, Spanish, French, German and Italian — in the app and on this site. Switch whenever you like.
Yes. IDarU lands on iOS and Android at the same time, and one challenge can mix friends from both platforms with zero difference.
