get to know maru

Your everyday life, connected a little at a time.

Meals and your CGM sit at the center.
Connect more — sleep, activity — and they become part of each day's context.

  1. 01

    Snap a photo of your meal.

    Log what you eat with a photo. AI estimates the food and portion, and you can correct it yourself. Add a short note for how you felt, too.

  2. 02

    Line it up with your CGM readings.

    Connect a compatible CGM and you can look back at how your glucose moved after each meal. It can take a little time for the data to reach maru.

    You'll need to arrange your sensor separately — maru doesn't sell them. Check the guidance at sign-up for supported devices and how to connect.

  3. 03

    Look back through the reports you receive.

    Each morning brings a look at the day before. At the end of a sensor session, you get a look at the whole stretch. Read back through what your meals and daily life have shown you.

Starting from whatever you already track,
your context builds up.

Apple Watch is one way in — for sleep and activity.
Weight connects through a different path: a compatible scale, or entering it yourself.

Your own recordsChoose what to connect

Start with whatever you already have — no pressure to add more.

You don't need to have it all.

Only records you've allowed to share and connected to maru are included. Apple Watch and a smart scale aren't required. Apple Watch doesn't measure weight itself, and not every item appears in every report.

your pace

Missed a photo one day?
Just pick it back up at the next meal.

This isn't an app about racking up a streak. It's about using whatever you did log as a clue, getting to know yourself a little at a time. We try to leave room for that.

If you get stuck on device or permission settings, check the guidance at sign-up, or reach out to support.
