Description
Ronin is a diary for adults with type 1 diabetes. You log glucose, insulin, carbs and notes. That is all it does.
Ronin never suggests a dose and never gives medical advice. Talk to your care team about treatment.
WHAT YOU CAN LOG
- Glucose, in mmol/L or mg/dL. Values are never coloured and never graded.
- Insulin: bolus, basal and corrections, with your own insulin names.
- Carbs, by hand or from a built-in food list. Note what the meal was.
- Ketones, if you turn them on.
- Notes: anything you want to remember.
YOUR DAY AND YOUR HISTORY
Today shows your last reading, the day's entries and a strip of the day's glucose. History shows a month at a time. Each square is a day, each mark sits where the reading sat. Nothing is graded.
FOR YOUR CARE TEAM
Export the last 30 or 90 days as a CSV file and share it however you like. It opens in Excel and Numbers.
EVERYTHING STAYS ON YOUR PHONE
Everything you log stays on this phone and in the phone's own backup. Ronin sends nothing anywhere and has no account. It asks for no permissions.
NO CHEERING
No points, no streaks, no colours telling you how you did. You write it down, Ronin keeps it.
Ronin is free and open source, from the people who make DiabetesNinja.
