Dameter's home screen: today's Slacker Score and a request from Namataro

The idea

Your fitness tracker wants you to move more.
Your phone wants you to scroll less.
Dameter wants the opposite.

Didn't leave the couch today? Be proud.
Stared at your phone all day? No apology needed.
You don't need discipline to be doing just fine.

Dameter is the iPhone app where not trying finally pays off.

0 steps

earns full marks.

500 points

is a perfect Slacker Score.

1 sloth

keeps you company.

What it does

Three things
your fitness app doesn't do.

And a few more that Namataro has quietly tucked away.

The numbers view of the diary screen: steps, distance, active calories, Screen Time and Namataro Level

01

A day of slacking, made visible.

Steps, Screen Time and more, boiled down to one score for how little you did. Your week shows up as a graph, too.

Namataro's diary screen, with yesterday's score and entry

02

Your yesterday, in a diary.

The next day, you'll find a diary entry from Namataro about how your day went. No scolding. No cheering. …Something like that.

03

A place to be, for no reason.

Beyond the score, there's a room that exists just to be looked at. What happens there, you'll find out when you open it.

Introducing

Namataro.

A sloth who showed up
from nowhere in particular.

He came to on top of a tree. Anything before that, he doesn't remember.
Now, inside Dameter, he's there beside you every day.
Not praising, not scolding. Just there.

Namataro

Résumé

Read this, and you'll like him a little more.

Species
Three-toed sloth. The only one in the world.
Height
About 45 cm. (182 cm)
Weight
Never measured. He doesn't move, so there's no point.
Home
A small room up a tree. One window.
Diet
Leaves. Occasionally, nuts.
Likes
Futons, sofas, kotatsu, rainy days, an empty schedule.
Dislikes
Travel, exercise, loud noises, the phrase "you can do it".
Talents
Not moving all day. Watching the sky. Talking in his sleep.
Catchphrases
"It's okay to be a slacker." "Let's laze around." And "…"
Birthday
November 3. Japan's Culture Day. Declared, by himself, a day for doing nothing.

Words

Things Namataro might say to you.

It's okay to be a slacker.

Namataro wasn't waiting.

Stains on the ceiling: 47.

No need to try hard.

Today's human is too dazzling.
Namataro can't look straight at you.

Rainy-day Namataro is invincible.
His excuses for staying under the covers multiply.

Diary

Namataro wrote these down.

Written every day, whether the human looks at it or not.
A few excerpts.

Monday, July 13

Monday.
The day of the week Namataro hates most, used up.
That alone deserves credit.

Wednesday, July 15

Namataro counted 32 clouds today, then lost interest.
32 is a fine place to stop.

Saturday, July 18

Today the human was so active
they seemed to live in a different world from Namataro.

Sunday, July 19

Sunday night, and the futon says "come back tomorrow too."
The futon fears Monday as well.

Before you start

No pressure. No guilt.
No homework.

Setup: just tap "Allow"

Allow access to Health and Screen Time, and it measures everything on its own. No daily logging needed.

Your health data stays with you

Your steps and Screen Time are scored right on your iPhone. Dameter never uploads the raw numbers.

No Apple Watch needed

Your iPhone alone can measure all five categories.

It's free. There are ads.

The app itself stays free, always. A small ad shows at the bottom of the screen (not while you have a supporter subscription). Every purchase is confirmed first, so you won't buy anything by accident.

Frequently asked

Questions
you might have.

Is there an Android version?

At present, iPhone only. The app is built around the iPhone's Health and Screen Time features.

If I change phones, can I carry my score history over?

There is no in-app transfer feature. See Support for details.

Can I use it without allowing Screen Time?

Yes. You can choose "Later" during setup and allow it afterwards from the app's Settings. Until you allow it, the Screen Time category scores 0 points and your score is calculated from the other four.

Is there a widget?

Yes. You can show today's Slacker Score on your Home Screen (small and medium) and on your Lock Screen.

Can I turn notifications off?

Yes. Each kind of notification can be turned on or off in the app's Settings. Just turn off the ones you don't want.

Namataro saying thank you Thank you for reading this far.

All that's left now
is to slack off.

Available on iPhone running iOS 26.2 or later.
