One metric, a few people, and nowhere to hide.

Ryzome is a social health app for iPhone and Android. Your group agrees on one number, everybody's number is visible to everybody, and none of it needs entering by hand.

01 · The one metric

The group picks it, not you.

When somebody starts a group they choose one of three metrics, and that choice binds everybody who joins. There is no per-person setting, and no way to be measured on something the rest of the group is not being measured on.

That single constraint is doing most of the work. If everyone picked their own metric, everyone would pick the one they were already winning, and the standing would stop meaning anything by the end of the first week.

Movement Steps

The default, and the one everybody already has a number for.

Ground covered Distance

Walking and running, for groups who would rather count miles than steps.

Recovery Sleep

The week where doing less is the point.

02 · The standing

Everyone sees where everyone is.

A week runs Monday to Sunday. Through it, every member of the group can open the app and see the same leaderboard: each person's name, each person's total for the group's metric, and the order that puts them in.

There is no private mode and no way to sit a week out invisibly. Joining a group is the consent, and it is the whole mechanism. When the week closes the standing settles, the week's winner is recorded, and a new week starts from zero.

03 · What the group sees

Visible, and only this far.

Visibility is the product, so it is worth being precise about how far it goes. The line is drawn in the database itself, not in the interface, which means it holds however the app is used.

What every member of your group can see

  • Your display name and the initial shown on your avatar.
  • Your total for the group's chosen metric over the current week.
  • How many days in the week you reached the group's daily target.
  • Your resulting position in the standing, and any weeks you have won.

What nobody else can see

  • Your day-by-day numbers. Individual daily records are readable only by you. Everything the group receives is an aggregate computed on the server; the underlying days never leave.
  • Any metric other than the one your group chose. If your group competes on steps, joining it does not expose your sleep.
  • Anything from your phone or wearable beyond the metric in question. Ryzome asks for read access to what it needs and nothing else.
  • Your groups, to each other. Two groups you belong to cannot see each other, and somebody in one has no way to learn about the other.

The privacy policy covers this in full, along with retention, deletion, and what happens to the data if you leave a group or close your account.

04 · It counts itself

Nothing to log, ever.

Ryzome has no diary, no check-in, and no button that means "I did it". Your day is already being counted by the hardware you carry, so the app reads that count and syncs it. Miss a day of opening the app and nothing is lost; the numbers are still there when you come back, and late-arriving data corrects itself.

Read, never written

Ryzome reads your metric and never writes anything back to your health records.

Whatever you wear

Apple Watch, Garmin, Whoop, Fitbit, or nothing at all, just the phone in your pocket.

Catches up by itself

Each sync re-reads the recent past, so a watch that syncs late still lands in the right week.

iPhone and Android

Your group doesn't have to agree on a phone. Only on a metric.

Getting a group together

One person creates the group, picks the metric, and shares a six-character invite code. Everybody else enters the code. There is no directory to be found in, no follower graph, and no way to end up in a group you were not handed the code for.

Ryzome is scheduled to launch in 2026 on iPhone and Android. For the company behind it, see about; to ask us something, get in touch.
