What Ronin does
A diary, kept the way a paper one was: you write down what happened, and you can read it back. Nothing is scored and nothing is interpreted.
No scores, no streaks
No points and no colours telling you how you did. Values are never coloured, graded or interpreted.
Carbs three ways
Search a food and count portions, weigh it on the kitchen scale, or photograph the plate for a proposal you correct yourself. An estimate is never presented as a measurement.
The month on one page
Each square is a day and the marks sit where the readings sat. Tap a day to read it back.
A target range, if you want one
Drawn as a band behind the day’s glucose. Display only, not a prescription. You set the range yourself.
Your units, your words, your file
mmol/L or mg/dL, your own insulin names, Swedish or English. Export a CSV for your care team whenever you want one.
About Ronin
Ronin is a diary for adults with type 1 diabetes. You write down glucose, insulin, carbs and notes. That is all it does. It is free, from the people who make DiabetesNinja.
No advice, ever
Ronin never suggests a dose and never gives medical advice. Talk to your care team about treatment.
Nothing leaves the phone
Everything you write down stays on this phone and in the phone’s own backup. Ronin has no account and sends nothing to us.
It asks for nothing
No camera permission, no location, no contacts. The Android version declares no permissions at all, so there is nothing to say yes to.
