Know exactly when you'll reach your goal weight.
AI-powered calorie tracking, meal analysis, progress forecasting and GLP-1 medication management — built into one beautifully simple app. Free to download on iPhone and Android.
Free on the App Store and Google Play.
Most diets fail because you can't see the future.
Plateaus, guesswork, and inconsistent tracking kill motivation. WeightLytic replaces hope with a clear, data-driven trajectory toward your goal.
Generic plans
Calorie guidelines built for averages — not your body, lifestyle, or schedule.
No visibility
You don't know if today's choice puts you closer to — or further from — your goal.
Slow feedback
Daily weight noise hides real trends. By the time you notice, weeks are gone.
One app. Every signal that actually matters.
We combine food, weight, exercise, and medication data into a single forecast that adapts as you live your life.
- Trend-based weight readings, not daily noise
- Photo-first AI food analysis in seconds
- Adaptive goal dates as your data evolves
- Built-in GLP-1 medication companion

We show a projected goal date with an honest confidence range — never a guaranteed result.

Is WeightLytic available yet?
Yes — WeightLytic is live and free to download on iPhone (App Store) and Android (Google Play).
How does the weight-loss forecast work?
WeightLytic fits a trend line to your logged weigh-ins and projects your goal date as a confidence range that narrows as you add data — never a guaranteed outcome.
Can it track GLP-1 medication like Mounjaro or Ozempic?
Yes. The GLP-1 companion logs doses, injection sites, side effects, supply and cost for Mounjaro, Ozempic, Wegovy, Zepbound and Retatrutide.
How does AI food tracking work?
Snap a photo and WeightLytic estimates the calories and macros, or scan a barcode or nutrition label. You review every estimate before it logs.
How much does WeightLytic cost?
There is a free tier. Premium is £3.33/mo billed annually (£39.99/yr, or £5.99 month-to-month) for the AI features and forecasting; Pro is £7.49/mo billed annually (or £9.99 monthly) for the GLP-1 companion. You can upgrade in-app.
Does WeightLytic give medical advice?
No. WeightLytic is a tracking and companion tool, not medical advice, and it never makes dosing decisions — those stay with your clinician.
