Create the dare
Set the daily goals: 100 push-ups, 20 pages, 10 minutes of meditation. Any goal you can count works — and when it's serious, turn on photo proof.
Private challenges between friends
Create a challenge, send the link and prove every day with a photo taken on the spot — confirmed by your friends. Lying to an app is easy. Lying to your friends isn't.
Ten seconds and you are on the list.
The essentials
Set the daily goals: 100 push-ups, 20 pages, 10 minutes of meditation. Any goal you can count works — and when it's serious, turn on photo proof.
Every invite is a private link that expires and can be revoked. Only people you approve get in, even if the link travels.
Log your progress and keep the streak. When a friend finishes the day, everyone else gets notified. Nobody wants to fall behind.

Built to last
Everything a challenge needs to stick — and nothing that turns it into a social network.
A photo taken on the spot, no camera roll. Your friends confirm it — the people who know your face and don't buy excuses. It disappears when the challenge ends. No other app has this.
Every completed day adds to your streak. The 3, 7 and 30 day milestones are recorded on your profile, per challenge.
A reminder before the day ends, at the time you choose. And an alert the second a friend finishes first.
Every challenge has its own chat. Jokes, excuses, and that nudge when someone is about to give up.
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.
By default it's an honor system: logging is manual and whoever makes up numbers only cheats themselves. For more serious challenges, the creator can turn on photo proofs taken on the spot and confirmed by friends.
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.
They're optional, per challenge: when you log the day you take a photo on the spot (nothing from the gallery) and your friends confirm it. 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.
