Take a photo of your meal and let AI instantly estimate the calories, protein, carbs, and fat. Or just type what you had — our AI understands natural language.
We believe in radical transparency. Here's exactly what we do — and don't do — with your data.
Everything you need to know before getting started.
Lejavu is free to download with no ads. Core features — including nutrition tracking, AI food scanning, workouts, sleep logging, and body metrics — are completely free. Lejavu PRO unlocks lifestyle tracking, long-term insights, and unlimited AI photo scans for $4.99/mo or $39.99/yr. A 7-day free trial is included.
Take a photo of your meal or pick one from your gallery. Our AI analyzes the image and identifies individual food items, estimating calories, protein, carbs, and fat for each. You can refine results by chatting with the AI — for example, "add more rice" or "I only ate half." Your photos are analyzed in-memory and immediately discarded — they are never stored.
AI features (photo scan, text analysis, workout generation) require an internet connection since they're processed on secure servers. However, manual logging (quick add, custom foods, water, exercises) works with your existing cached data. All data syncs automatically when you're back online.
Lejavu uses the scientifically validated Mifflin-St Jeor equation based on your height, weight, age, gender, activity level, and fitness goal. Protein is calculated per kilogram of body weight (not a flat percentage), fat gets a minimum 25% floor for hormonal health, and carbs fill the remainder. You can recalculate at any time from your Profile.
Absolutely. Your data is stored on secure, SOC 2 compliant infrastructure (Supabase). All connections use HTTPS encryption. We never sell your data, show ads, or use third-party trackers. You can export all your data or permanently delete your account at any time. Read our full Privacy Policy →
Yes! Lejavu tracks water intake, sleep, body metrics (weight, body fat, body water), and 7 lifestyle habits: mood, alcohol, tobacco, socializing, family time, meditation, and caffeine. Each tracker can be individually enabled or disabled from your settings.
The leaderboard ranks users by XP earned from daily logging activity (up to 15 XP/day). It's a fun way to stay motivated. You have full control — toggle your visibility off in Profile settings and your name and avatar will be anonymized on the board.
Currently, Lejavu is available on Android via Google Play. iOS support is planned for a future release. Stay tuned!
