Flux: Mounjaro Tracker

Flux is the ultimate Mounjaro and Zepbound tracker for your GLP-1 weight loss journey. Log injections, track weight loss, monitor estimated tirzepatide levels, and build daily weigh-in streaks. Smart injection site rotation, AI-powered insights, and full Apple Health sync make Flux the only weight loss companion you need.

Injection Tracking & Dose Reminders

Log every Mounjaro or Zepbound injection with dosage, site, and frequency. A visual countdown ring shows when your next dose is due, and smart site rotation suggestions recommend the best injection location based on weight loss performance and side effect history at each site.

Estimated Tirzepatide Levels

A built-in pharmacokinetic model simulates your Mounjaro or Zepbound concentration over time, showing trough, current, and peak tirzepatide levels so you understand how your medication works between doses.

Weight Loss Tracking & Weigh-in Streaks

Track your weight manually or sync automatically with Apple Health. A weigh-in history grid tracks every day you log your weight over the past year, rewarding daily consistency with a streak counter. See your progress toward your goal weight, view trends with a 7-day moving average, and get projected goal dates based on your current rate of loss. Smooth, colour-coded charts show your weight loss journey across every dosage tier.

Share Your Progress

Show off your weight loss with a shareable Journey Card designed for social media. See total weight lost, monthly breakdowns, and dosage history in one beautiful graphic. A privacy toggle lets you hide medication details before sharing.

Daily Health Dashboard

Monitor calories, protein, water intake, steps, and sleep quality pulled from Apple Health in one clear daily view. Celebrate hitting your daily goals with full-screen confetti. Customise your water quick-add buttons to match the bottles and glasses you actually use.

AI-Powered Weight Loss Insights

Get personalised, encouraging commentary on your Mounjaro or Zepbound progress. Flux uses AI to highlight key trends in your weight loss, medication levels, and overall journey. Toggle individual insights on or off to see only what matters to you.

Side Effect Tracking

Log and review side effects with dates and notes. Flux identifies patterns between injection sites and side effects to help you make informed choices about site rotation.

Charts & Analytics

Interactive charts show your weight history colour-coded by dosage tier, injection site distribution, and more across custom time ranges from two weeks to all-time. A stable moving average trend indicator cuts through daily noise to show whether your rate of weight loss is increasing, steady, or slowing.

Weight Loss Predictions

Set target weights and target dates, then see projected timelines based on your current or overall rate of loss. Supports kilograms, pounds, and stones. Passed targets are automatically cleared so you can focus on what is ahead.

Apple Health Integration

Flux syncs with Apple Health to read your weight, calorie intake, protein intake, step count, and sleep data. Weight entries logged in Flux are automatically saved back to Apple Health. Your health data stays on your device and is never uploaded to external servers.

Import & Export

Back up your data as JSON or import from a previous Flux or Shotsy export. Your health data stays in Apple Health where it belongs.

Personalised Setup

Set your goal weight, daily targets for water, calories, protein and steps, choose your preferred units (kg, lbs, stones), customise your weigh-in grid colour, and configure injection reminders so you never miss a dose.
