For iPhone

75 days.
Kept together.

A private 75-day challenge you do on your own or with one friend. No feed, no followers, no strangers. Just today’s list — and optional progress sharing with people you choose.

Inside the app

Built around today, not forever.

Every screen does one job and then gets out of your way.

Today

One tap each, and the day is done.

Two rings — yours and theirs. Every item has its own tick, so neither of you has to ask how the other did.

  • No ranking and no winner. You are on the same day.
  • Your day ends at midnight where you are, not where they are.

Progress

All 75 days on one grid.

Miss one and you keep going — nothing resets. Past days are locked, so the record stays honest.

  • Water, weight, photos and notes, tracked privately.
  • Weigh-ins and notes never leave your iPhone.

Circle

Share progress without creating a group.

Connect your solo challenge or partnership with people you trust. Each connection stays separate, so your friends never become one another’s audience.

  • See day, check count, streak, and the 75-day map — not weight, notes, or Progress Photos.
  • Both sides approve before anything is shared, and anyone can disconnect at any time.

Moments

One photo each. No endless feed.

Share one intentional photo with your challenge partner each day. It clears at midnight instead of becoming a permanent feed.

  • Nothing sends until you review it and tap send.
  • React with four quick signals — no comments or inbox.

Private by default

Notes, weight, and progress photos never leave your iPhone.

Works with no signal

Tick things off anywhere. It syncs when you are back online.

The daily challenge stays small

Start solo or with one partner. Circle never adds people to the challenge you keep together.

How it works

Four steps, then 75 days.

01

Pick what you’ll do

Choose 3 to 8 things to do every day. Start from Hard, Medium, or Soft — or build your own list.

02

Go alone or add a friend

Start solo, or invite one person to share the daily challenge with you. A challenge always has one or two people.

03

Tick things off

Check things off as you go. Your day ends at midnight where you are — not where they are.

04

Get to day 75

Miss a day and you carry on — nothing resets. At the end, you get a recap of the full challenge.

Privacy

The personal stuff never leaves your phone.

Your most personal data stays where it belongs: on your iPhone, in your control.

Stays on your phone

Your notes, your weigh-ins, and your progress photos. We never receive them, so we can never hand them over.

Sent only if you send it

A Moment reaches only the people you choose after you review it and tap send. Location and camera details are stripped first.

Delete from the app

Confirm account deletion in Settings. Access ends right away; our privacy policy explains deletion timing and limited retention.

Start when you like

Day 1 is whenever you say.

Pick a start date and what you’ll do each day. Want company? Send one person a code.
