Just want the app for now? As designed, the app on its own would let you log meals with your phone's camera, set reminders, track refills and share with your circle, without the wearable noticing things for you. Pricing to be decided.
This is the intended design. Features, size and specs may change as we build it, based on what engineering allows. If you join, we'll tell you about meaningful changes before you decide, and the choice is always yours. Founding members get updates and the first chance to order, with final prices shown before you decide. Want to test an early prototype instead? That's the alpha test below; places are limited.
Questions
Straight answers.
Who is it for?
Every kind of diabetes: Type 1, Type 2, LADA, gestational and more, with or without insulin. The reminder to check whether you need to bolus only appears if you use insulin. People without diabetes who want to understand their metabolism are welcome too; Tsumo is built first for diabetes, so that is where it goes deepest.
Is Tsumo medical advice?
No. As designed, Tsumo recognizes and logs what you eat, drink and take, estimates macros and reminds you on the schedule you and your care team set. It doesn't diagnose, treat or recommend doses, and it hasn't been evaluated by the FDA. Its regulatory status will be confirmed before launch.
Does Tsumo dose insulin?
No. Tsumo estimates macronutrients only. If you use insulin, it can remind you that you've started eating, so you can check whether you need to bolus. Every treatment decision stays with you and your care team.
What would it keep, and what would it hear?
As designed, not continuous footage: selected snapshots tied to moments that matter, like a meal or your meds, so you and the people you choose can see what an estimate was based on. It's designed to listen for meal context, like "dressing on the side," and keep a short note rather than audio. We're working on reducing what's visible of people nearby and on letting you delete entries, with any retention rules explained up front. It's designed so you can pause it.
Does it work with my CGM and pump?
That's the plan. Tsumo is designed to sit next to the devices you already wear, planned to start with your phone's health app, and to add the meal and medication context they can't see.
Can a child use it?
As designed, yes, through a parent's account. The parent sets it up and decides who sees what. The founding list is for adults 18 and over.
Is this a real product yet?
Not yet. Tsumo is a concept in development. The images are design renders and the films are made with AI video. What you see is the intended design; details may change as we build it, based on engineering limits at the time. Founding members hear about meaningful changes before anything is final, and the choice to go ahead is always yours.
Want to test it first?
We're planning a small alpha test of early prototypes. Apply in a minute; it doesn't guarantee a spot.
