About this app

Challenges with friends, with proof that counts.

DonRetto turns a friendly dare into a Retto everyone can follow: clear rules, photo evidence, and a group that decides whether it counts.

HOW IT WORKS

Create a private group and invite your people with a code. Inside it, set up a Retto: name it, write the rule that decides what counts as done, then set how many days it runs, what time the day closes, and how many sends are allowed. Everyone accepts the same rules before their evidence scores.

TWO WAYS TO SET THE GOAL

• Shared goal: everyone is after the same target. Same challenge, same bar.
• Personal goal: each person sets their own and sends what proves their progress. Useful when a group trains together but is not at the same level.

PROOF, NOT PROMISES

Sending evidence means a photo — from your camera or your library — plus an optional note. An admin reviews it, or the whole group does by vote, depending on how the Retto is set up. Only approved evidence scores: the ranking is earned by decisions your group actually made, not by how many photos you sent.

And nothing is wasted on a maybe. Sending holds one of the day's opportunities, but it is not spent until someone decides. Withdraw it while it waits and you get it back in full.

WHAT YOU SEE EVERY DAY

• Your ranking, with each participant's points and days completed.
• A strip of days that answers when, not just how much: which days you made, and which stayed empty.
• The group streak: consecutive days the group kept it up. It is shared, not individual, so easing off shows.
• The group wall: if the Retto allows it, approved photos stay visible to members. Seeing what everyone else did is half the motivation.
• A bell on Home with your alerts: when it is your turn to review, and when yours was decided.

WHAT IT IS FOR

Anything that is easier to keep up with company: training, running, swimming, reading, studying, dropping a habit, settling a bet. It works the same for three friends as for a coach and their team — whoever manages the group sees each participant's progress and can review what they send.

IDEAS TO START FROM

Explore holds Retto setups other groups chose to share: the name, the rule and the schedule, ready to copy into yours. Groups, members, evidence and rankings never appear there. Only the setup, and only if somebody chose to publish it.

MAKE IT YOURS

Pick an avatar from the catalogue — runners, bicycles, mountains, boxing gloves, boards, waves — and give it a colour. It is yours, and it shows in the ranking next to your name.

PRIVATE BY DEFAULT

Your groups are private and joined by invite code. There is no public feed and no group directory: nobody discovers strangers here. Your evidence reaches only whoever reviews it, or the group if the Retto shares it. There is never a public link.

You can report content or people and block a member. You can also deactivate your account whenever you like, or delete it along with your data from your profile — no email to write, no form to fill in.

No ads. No tracking. No advertising SDK.

Available in English and Spanish.

Bring the ganas. Keep the rules clear. Dale al Retto.
