Private challenges between friends

I dare you.

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.

  • Data hosted in the EU
  • Available in 6 languages
  • No vanity feed. Just results.

The essentials

Three steps, zero friction

1

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.

2

Send the link

Every invite is a private link that expires and can be revoked. Only people you approve get in, even if the link travels.

3

Push each other

Log your progress and keep the streak. When a friend finishes the day, everyone else gets notified. Nobody wants to fall behind.

Guided tour

The app, screen by screen

Swipe through and see what's waiting: progress at a glance, friends close by, zero distractions.

Home

Your challenges for today, with progress rings and streaks always in sight.

Challenge

Who's done today, who's still due — and the group's streaks side by side.

Chat

One private chat per challenge, perfect for teasing and celebrating.

Feed

Only finished challenges, told by the people who did them — zero vanity.

Trophies

A shelf of medals graded by rarity, not a list — with live streaks called out up top.

Built to last

Friendly pressure, by design

Everything a challenge needs to stick — and nothing that turns it into a social network.

Proof your friends confirm

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.

Streaks and trophies

Every completed day adds to your streak. The 3, 7 and 30 day milestones are recorded on your profile, per challenge.

Notifications with timing

A reminder before the day ends, at the time you choose. And an alert the second a friend finishes first.

Talk where the challenge happens

Every challenge has its own chat. Jokes, excuses, and that nudge when someone is about to give up.

Why IDarU

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.

Trust

What you can verify today

We haven't launched yet, so we won't invent user counts or testimonials. What's left is what's already written and you can check.

  • Your data stays in the EU

    Everything hosted in Frankfurt, under GDPR. It never leaves Europe.

  • No third-party trackers

    No third-party analytics and no ad pixels on this page. Open your browser network tab and see for yourself.

  • Private by default

    No open profiles, no discovery. The only public thing is the feed of finished challenges — opt-in, post by post, and never with your photos.

  • Six languages

    App, site and privacy policy in Portuguese, English, Spanish, French, German and Italian.

  • Free between friends

    Daring your friends is free and will stay that way. A public promise, not a pricing tier.

  • Delete means delete

    Delete your account and it all goes: challenges, progress, trophies and photos. No grace period.

Questions

Everything you might ask

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.
