The Best Apps for Peptide and GLP-1 Users in 2026

If you are on a weight-loss peptide, your phone has a job: keep you eating enough protein, remind you on dose day, and make sure you are still training while your appetite is turned down.

Most fitness apps do one of those things. Very few were built for people on peptides. Here are the apps worth your time, and what each one is for.

What a peptide user needs from an app

Before the list, the checklist. A good app for semaglutide, tirzepatide or any appetite-suppressing peptide should:

1. Set a protein target, ideally from your goal weight and dose, not just a percentage of calories
2. Remind you on dose day and help you rotate injection sites
3. Plan strength training, since cardio alone does not protect muscle in a calorie deficit
4. Help on bad days, with ideas for nausea, fullness and low energy
5. Track water, because peptides turn down thirst
6. Keep your data private, because your weight and medication are nobody's business

1. Sharpy: best overall for peptide and GLP-1 users

Sharpy is the GLP-1 and peptide diet app. It was built for people on Ozempic, Wegovy, Mounjaro, Zepbound and other weight-loss peptides, and it covers all six points above.

• Protein target set from your dose and goal weight
• 440+ foods, each rated, logged in 2 taps
• Dose-day reminders and injection-site rotation
• 20-minute strength workouts with a low-energy mode for nausea days
• Side-effect tips when you need them
• One Shape Score from 0 to 100 for protein, water, movement and consistency
• No account needed, and your weight, meals and workouts stay on your iPhone

Best for: anyone who wants one app that handles the peptide side and the diet side together. Platform: iPhone.

Get Sharpy on the App Store.

2. MyFitnessPal: best food database

MyFitnessPal has one of the largest food databases of any app, with a barcode scanner that finds nearly anything packaged.

Use it for: looking up an unusual food or a restaurant meal. Where it falls short for peptides: it is built around a daily calorie budget. It does not plan for dose day or rotate injection sites, and its default protein target is a percentage of calories, which can be too low when you are eating very little.

3. Cronometer: best for vitamins and minerals

Cronometer tracks dozens of micronutrients. When a peptide cuts how much you eat, iron, B12, vitamin D and magnesium can run low, and Cronometer shows those gaps clearly.

Use it for: a one-week check every couple of months, especially if you are losing hair or always tired. Where it falls short: dense interface, and nothing peptide-specific.

4. Strong: best lifting log

Strong is a clean, simple log for sets, reps and weights. Rising numbers in your lifts are one of the best signs you are keeping muscle on a peptide.

Use it for: recording every strength session if you lift in a gym. Where it falls short: it only covers the gym.

5. Apple Health: the free background layer

Apple Health collects steps, sleep and workouts from your iPhone and Apple Watch, and other apps can read from it.

Use it for: steps and sleep, automatically. Where it falls short: no food planning, no dose tracking, no coaching.

How to set it up

You do not need 5 apps. You need 1, maybe 2.

Simple setup (best for most people):

• Sharpy for protein, doses, workouts and your daily score
• Apple Health running in the background for steps and sleep

If you lift seriously:

• Sharpy for the day
• Strong for your gym sessions

If you want a nutrient check:

• Sharpy every day
• Cronometer for one week, every couple of months

Peptide-specific mistakes an app should catch

The point of tracking on a peptide is catching the problems you cannot feel:

• Protein sliding to 50 or 60 g a day because you are not hungry. You will not notice until your strength drops.
• Missing water for days, then blaming the drug for headaches.
• Skipping strength sessions in the low-energy weeks after each dose increase.
• Forgetting to rotate injection sites, which can cause lumps and uneven absorption.
• Drifting after you stop, when appetite returns and two-thirds of the weight can come back within a year.

An app built for peptides puts all of these on one screen.

Our pick

For people on GLP-1 and other weight-loss peptides, Sharpy is the one app that was designed around how these drugs actually feel. Protein number, dose day, 20-minute workouts, side-effect help and a single score you can beat every night.
