Offline-first diary for iOS and Android
Glytrio
A calm diabetes diary for logging glucose, food, insulin, medication, activity and wellbeing, then turning everyday records into a clear doctor report.
No required account, no ads and no default cloud. Core access is free in Russia, Ukraine, Armenia, Georgia and Belarus; other countries move to a paid model later.
Why core is free in 5 markets
Essential self-tracking should not depend on store payments
Because App Store and Google Play payments and availability are restricted in Russia, Ukraine, Armenia, Georgia and Belarus, Glytrio keeps core features free there: diary, glucose, insulin, food, medication, reminders, analytics, PDF/CSV and backup. These are everyday health self-tracking tools, not entertainment premium features.
The international paid model will be enabled separately through store billing and does not change free access in those countries.

Feature set
What is already in the product
This list is based on the PRD, feature wiki and Flutter code: Diary/Food/Analytics/Reminders/Profile tabs, Drift storage, reports and backup.
Daily log
A factual diary, not a medical adviser
The daily timeline supports glucose, insulin, food, medication, activity, wellbeing, weight, ketones, hypo events and notes.

The food tab includes 85 generic RU products, carbs per 100 g, GI, favorites, recent items, custom products and saved meal templates.

Analytics
Trends without clinical judgement
Analytics covers day, week, month and 90 days: average glucose, min/max/count, SD/CV, hypo/hyper levels and after-meal observations.
- below/in/above range
- 90-day doctor mode
- meal-to-glucose links
Reports
PDF/CSV for appointments
Reports combine diary entries, glucose, food, insulin, clinical facts, glucose charts and a 90-day preset for a doctor visit.
- PDF chart
- CSV export
- no web portal required
Offline
Local on the device
The MVP does not require a backend. Data stays in SQLite/Drift, backup is user-initiated and encrypted exports verify integrity.

Profile
Profile and clinical facts
Profile stores language, units, target range, XE settings, therapy type, HbA1c, blood pressure, lipids, kidney labs and annual exams.

Jobs to be done
JTBD: when Glytrio helps
These scenarios start with the user task, not with a menu of screens.
When a reading needs to be logged in seconds
Open, enter glucose, save
Fast entry uses a large keypad, contexts such as fasting / after meal / bedtime and the user’s preferred units.When food and glucose need context
Link a meal to a later glucose reading
Glytrio stores meal-to-glucose links and later shows neutral observations without causal or treatment advice.When a doctor appointment is coming
Build a 7, 30 or 90 day report
PDF/CSV exports glucose, food, insulin, reminders, weight and clinical facts in a format that is easy to bring to a visit.When a parent keeps the diary
See the child’s day without account friction
One local profile on the device, quick records and a readable daily history without mandatory registration.When labs and related facts matter
Keep HbA1c, BP, lipids and kidney labs near the diary
Low-frequency clinical facts live in Profile and flow into the doctor report as records, without color judgement or diagnosis.Medical boundary
Glytrio is a diary, not a doctor
The app helps people record and review history. It does not replace a clinician, diagnose conditions or manage therapy.
- does not calculate or recommend insulin doses
- does not tell the user how much insulin to inject
- does not control pumps and is not CGM
- does not diagnose or predict medical outcomes
