Two ways to use Track4U
Pick the option that fits your style. Both are free. Both give you full control.
Both options are 100% free. The only cost is AI usage, which you pay directly to OpenAI.
How it works
From photo to macros in seconds
Three simple steps. No searching food databases. No measuring cups. Just point, shoot, and track.
Snap a photo
Point your camera at any meal — breakfast, lunch, dinner, or snacks. The AI handles everything from a single apple to a full dinner plate.
AI analyzes instantly
Advanced vision AI identifies every item, estimates portions, and calculates accurate nutritional data — calories, protein, carbs, fat, and fiber.
Track your progress
Review the results, make adjustments if needed, and save. Watch your daily totals update in real-time on your personalized dashboard.
Features
Everything you need, nothing you don't
Built for speed and simplicity. Track your nutrition without the complexity of traditional apps.
AI Food Scanning
Point, shoot, done. Vision AI identifies food items and estimates nutritional content from a single photo.
Personalized Goals
Science-backed macro calculations based on your body, activity level, and whether you want to lose, maintain, or gain.
Progress Insights
Beautiful charts show calorie trends, macro distribution, and weekly patterns. See what's working.
Meal History
Browse past meals by date, search by name, and track patterns over time. Tap any entry to edit.
Privacy & Security
Your data. Your API key. Your control.
Most apps lock you into subscriptions and harvest your data. Track4U flips the model — you bring your own AI key, pay only for what you use, with no billing visibility on this end.
BYOK = Bring Your Own Key
Use your own AI API key. Average cost: ~$0.01 per food scan with GPT-5.2. That's ~$5/year at 10 meals/week — vs $40-80/year for subscription apps. No commitment required.
Encrypted Storage
Your API key is encrypted with AES-256-GCM before it ever touches the database. It can't be read — only you can use it.
Your Key, Your Control
Bring your own API key. You're billed directly by the AI provider — no usage tracking or markups.
Data Stays Private
Food images are processed and discarded. Only nutritional data is stored, not photos. Your diet is your business.
Fully Open Source
Every line of code is public. Audit it yourself, self-host it, or contribute improvements. No black boxes.
Built in the open
I enjoy building practical tools and sharing them. Every line of code is public. Fork it, self-host it, learn from it — it's all there. No vendor lock-in, no hidden agendas.
