Best App for Tracking Mounjaro & Zepbound (Tirzepatide) in 2026

Tirzepatide — sold as Mounjaro for type 2 diabetes and Zepbound for weight management — is the fastest-growing GLP-1 medication on the market. Its dual GIP and GLP-1 receptor agonism means more potent results, but also a more complex titration schedule: starting at 2.5mg and stepping up every four weeks through doses of 5mg, 7.5mg, 10mg, 12.5mg, and 15mg.

That titration ladder alone is reason enough to track carefully. Six potential dose levels, each lasting at least a month, means your history matters. Your provider needs to know when you titrated, what side effects appeared at which dose, and how your weight responded to each step up.

Most apps aren't built for this. Here's what actually matters in a Mounjaro or Zepbound tracker — and what sets a purpose-built GLP-1 app apart.

What makes tirzepatide tracking different

Tirzepatide has a few characteristics that make tracking more important — and more nuanced — than with other medications:

• Long titration schedule. With six possible dose levels stepped up monthly, you can be on Mounjaro for six months before reaching your maintenance dose. That's six distinct phases of side effects, weight response, and appetite change to correlate.
• Strong appetite suppression. Tirzepatide users often report dramatic reductions in food noise and appetite. Tracking nutrition helps you ensure you're still eating enough protein and not under-fueling muscle maintenance.
• Injection site consistency. Like all GLP-1 injectables, Mounjaro requires rotating sites — abdomen, thighs, upper arms — to prevent lipohypertrophy and maintain consistent absorption. A tracker with site rotation history is essential.
• Plateau and stall recognition. Weight loss on tirzepatide isn't linear. Stalls are normal. Tracking weight weekly — rather than obsessing over daily fluctuations — reveals the real trend through the noise.

What to look for in a Mounjaro tracker app

Not all health tracking apps understand GLP-1 therapy. Here's the checklist:

• Supports tirzepatide specifically — the app should know what Mounjaro and Zepbound are, and ideally support all six dose levels (2.5mg through 15mg) rather than just free-text fields.
• Titration timeline — you should be able to see your full dose history on a visual timeline, so it's clear when you went from 5mg to 7.5mg and how long you stayed at each level.
• Side effect logging — nausea, constipation, fatigue, injection site reactions. Tirzepatide side effects often peak 1-3 days after injection; logging them alongside injection dates reveals the pattern.
• Weight trend, not just weight — a weekly weight chart with a trend line is far more useful than raw daily numbers. You want to see the signal through the noise.
• Nutrition tracking with protein focus — preserving muscle on aggressive tirzepatide weight loss requires adequate protein. An app that tracks protein goals specifically (not just total calories) is more useful than a generic food diary.
• Export for your provider — your endocrinologist or prescribing provider benefits from seeing your titration history, weight trend, and side effect log. A CSV export formatted for easy sharing saves time at every appointment.

How Steady handles Mounjaro & Zepbound

Steady was built from the ground up for GLP-1 and GIP/GLP-1 users. When you set up your medication, you select Mounjaro or Zepbound, choose your current dose, and set your weekly injection day. From there:

• Injection logging captures dose, site, side effects, and any notes in a single flow. Your full titration history is always one tap away.
• Site rotation tracking shows where you last injected and helps you avoid repeating the same spot.
• Weekly reminders notify you on your injection day so you never miss a dose — and don't accidentally take it twice.
• Weight trend chart shows your trajectory week over week, filtering out daily fluctuations so you can see real progress even through a plateau.
• AI nutrition logging (Premium) lets you photograph your meal for instant macro estimates — protein, calories, carbs, fiber, fat — with a specific protein goal tracker so you hit your daily target even with reduced appetite.
• CSV export (Premium) gives your provider a complete record of every injection, weight log, and nutrition entry.

There's also a home screen widget for iPhone that shows your next injection countdown and current weight — so you never have to open the app just to check when your next dose is.

Free to try

Steady is free to download, with a 7-day trial of all Premium features. Core injection tracking, weight logging, and check-ins are free forever. Premium adds AI food logging, the supply tracker, body measurements, and CSV export for $4.99/month or $99 lifetime.
