Count it.
Together.

Push-ups, kilometres, pages, cold showers. Pick something worth counting, send your people one link, and every single entry lands in the same total.

  • Your first challenge takes 30 seconds
  • One link — they can look before they install
  • Works solo or with the whole team

How it works

Three steps. Then the number does the work.

No boards to configure, no spreadsheets to keep alive. A challenge is a title, a target, and everyone who said yes.

Pick a thing worth counting

Name it, set the target, choose the unit. 1,000 push-ups before June. 500 km by summer. 12 books this year. You are counting before the kettle boils.

Send one link

Share the link, let them scan the QR, or read out the code. They see the challenge and its live standing on the web first — installing comes after they are curious.

Watch the number climb

Every tap from every member adds to the same total. Progress bar, streaks and best days do the rest: nobody wants to be the one who stopped.

What it does

Built for the one thing group goals always get wrong: keeping everyone counting.

One total, everyone's effort. Your 20 and their 30 land on the same number. The challenge screen shows who counted what, so nobody's work disappears into an average.

Counting takes one tap

Presets for the numbers you log every day, a custom field for the rest. The total moves the instant you tap — it never waits on the network.

Invite by link or QR

One link per challenge. Share it, show the QR, or read out the code. Replace it whenever you like — everyone already in stays in.

Stats that keep you honest

Total, entries, average per entry, current streak, this week, this month — and the best day you have ever had.

A nudge at your hour

Choose a time and get one quiet daily reminder. Count, and it stops bothering you for the day.

Pin what matters

Pinned challenges sit on the first screen you open, counter included. Open, tap, done — no navigating to log a set.

No password to forget

Sign in with your email and a one-time code. No password, no social login, no ads — just the number you came for.

Invites

One link. Everyone's in.

The moment a group goal needs a sign-up form, half the group is gone. So an invite here is a link anyone can open, look at, and join from.

  • They see it before they installThe link opens a page with the challenge, the live total and the progress bar. Curiosity first, download second.
  • The QR does the talkingPoint a phone camera at it in the gym, the classroom or the office kitchen. It opens the app if they have it, the page if they do not.
  • The invite survives the app storeInstall, open, and the challenge is still waiting. Or type the ten-character code by hand under “Redeem code”.
  • You decide who is inReplace the link any time. The old one and its QR stop working immediately; everybody who already joined keeps counting.

Questions

Short answers

Do my friends need the app to see the invite?

No. The link opens a web page showing the challenge, the live total and how far along it is. The app is only needed to add counts.

Can I count on my own?

Yes — every challenge starts solo. Invite people whenever you feel like it and their entries join the same total from that point on.

What can I count?

Any whole number: reps, kilometres, pages, cups, minutes, days. You name the thing, set the target, and count in whatever steps suit you.

Does an invite link expire?

It works until you replace it. Replacing kills the old link and its QR code immediately, while everyone who already joined keeps counting.

How do I sign in?

Type your email address, then the one-time code that lands in your inbox. There is no password to choose or forget.

I installed the app before opening the link. Now what?

Open the app and enter the ten-character invite code under “Redeem code” on the home screen. Same result.

Pick a number.
Invite your people.

The first challenge takes thirty seconds. After that the total climbs on its own — because somebody always wants to be the one who added the last rep.
