Pronounced sah-noh-VOH-yoh — Esperanto for "health path."
Daily points, smart food logging, medication tracking, glucose & blood pressure, plus 9 printable medical reports — all in one fast app that respects your privacy.
Sanovojo combines daily logging, smart coaching, clinical-quality reports, and a social layer that keeps you accountable — without the noise of typical health apps.
Three ways to log food without typing every nutrient yourself, plus weight, water, exercise, glucose, BP, and meds — all on a single screen.
The Coach reads your day — what you logged, your check-in mood, the time, your streak — and gives you the right nudge instead of generic motivation.
Nine printable reports — every one can be printed, saved as PDF, or emailed directly to your provider with a custom note.
The accountability layer most health apps skip. Add friends by email, see their live streak/points/water, and challenge each other on a 7-day battle.
Here's everything Sanovojo ships with, packed into one app.
A simple daily target that grows with exercise. Weekly bank rolls over.
Mood-aware, time-aware, goal-aware nudges throughout the day.
Open Food Facts + USDA FoodData Central lookup.
Gemini AI identifies the meal and estimates nutrition.
One-shot food query → calories, macros, sodium, fiber.
RxNorm autocomplete, dose timestamps, 14/30-day adherence.
Optional advanced-health logging with TIR + est. A1C.
Trend chart, 7-day moving average, goal-aware coaching.
Quick-log presets + custom workouts + 7-day bar chart.
FDA's nine major allergens auto-detected on every log.
Live stat leaderboard, five-emoji reactions, posts.
Send a 7-day battle to a friend. Scores tick automatically.
Print, save as PDF, or email directly. Each report respects your goals and frames the data clinically — no fluff.
Most health apps either nail food logging OR medication tracking OR clinical reports — Sanovojo does all three, and respects your privacy doing it.

Sanovojo computes your daily point target.
Barcode, photo, AI search, or quick-add presets.
The Coach, your streak, and your Squad keep you honest.
Your food log, weight, glucose, BP, and medications are encrypted in your browser before they leave your device. Zero-knowledge means we can't read them.

sah-noh-VOH-yoh — emphasis on the third syllable (VOH). The "j" is pronounced like an English "y".
It's Esperanto for "health path" — sano = health, vojo = path. The name reflects what the app does: helps you walk a steady path toward better health, one daily log at a time.
Yes. No subscription. No ads. No data selling. The app is a static site backed by Supabase (whose free tier is generous), and the developer just runs it.
Yes. Sanovojo is a Progressive Web App (PWA). After the first load, every screen — Today, Log, Progress, Health, Friends, Settings — works offline. New entries sync to the cloud the next time you're online.
Yes. On iOS, open in Safari and tap the share button → "Add to Home Screen." On Android Chrome, look for the install prompt or the menu's "Install app" option. Once installed, Sanovojo runs in its own window with no browser chrome.
CSV import from Apple Health, Samsung Health, and Yunmai (via the Apple Health bridge) is on the roadmap — both platforms let you export your data and Sanovojo will parse it. Fitbit and Withings have public OAuth APIs and are also planned. Apple Health and Samsung Health themselves are mobile-platform-locked and can't be read directly from a web app — that's a hard browser limitation.
Pretty good for common foods — Gemini is solid at brand recognition and portion estimation. For foods that affect medical decisions (allergens, exact carbs for insulin dosing), always sanity-check the values against the package label. Sanovojo falls back to USDA FoodData Central when the AI is unsure.
Your data is encrypted with a key derived from your password. We don't know the password. We can't reset it. The encrypted vault becomes unrecoverable. That's the trade-off for true zero-knowledge encryption — it's the same model as services like Bitwarden, Tresorit, and Standard Notes.
No. Sanovojo is a logging and reporting tool for personal use. Use the printable reports to have better conversations with your doctor — don't use the app as a substitute for clinical guidance.
Sanovojo's source is on GitHub. Issues, pull requests, and forks are all welcome.
The demo loads with 30 days of seeded data — every report and chart shows real shape from the first second.
