Get Ignia
A calorie and protein tracker that learns your real metabolism from your weight trend — and logs your lifting in the same app. Free, no ads, no paywall.
Requires iOS 16 or later. iPhone only.
No app store? No problem.
Ignia also runs as a full offline web app in any browser — same account, same data, nothing to install.
What you get
- Adaptive targets. Most apps hand you one calorie number and never change it. Ignia recalibrates from your own weight trend and intake, so progress doesn't stall.
- A real training log. Workout templates, sets/reps/RIR, double-progression suggestions, plate calculator, warm-up generator. No other macro tracker ships this.
- Fast logging. Scan a barcode, search USDA FoodData Central and Open Food Facts, type a meal in plain language, or tap a saved preset.
- An AI coach grounded in your own logs — not generic advice.
- The rest of the picture. Fasting timer, body weight and measurements, body-fat estimate, weekly insights, weight-trend projection.
- Your data stays yours. Import from MyFitnessPal, Lose It! or Cronometer; export to CSV anytime; delete your account from inside the app.
- English and Spanish (Puerto Rico), fully translated.
Common questions
- Is it really free?
- Yes. Every feature is free. There's an optional tip if you want to support development — it unlocks nothing, because there's nothing locked.
- Are there ads?
- No ads, no data selling, no cross-site tracking. See the privacy policy.
- When is the Android version out?
- In testing. Until then the web app works well on Android — open ignia.fit/app in Chrome and choose "Add to Home screen".
- Can I move my history over from another app?
- Yes — Settings → Data imports MyFitnessPal, Lose It! and Cronometer CSV exports.
- How is this different from MyFitnessPal or MacroFactor?
- MyFitnessPal gives you a static target and no training log. MacroFactor has adaptive targets but no training log, and costs about $72/year. Ignia does both, free. Full comparisons: vs MyFitnessPal, vs MacroFactor, vs Lose It!, vs Cronometer.
