The Best GLP-1 Tracker Apps in 2026

The best GLP-1 tracker app in 2026 depends on whether you want to track the medication, the food, or both. Most apps do one side well and leave the other thin. The picks below cover the honest strengths and limits of each, including ours, so you can match an app to what you actually need.

Shotsy is one of the most established names for injection tracking. It does the medication side cleanly, with dose logging, shot reminders, weight trends, and a tidy history you can share with a clinician. The gap is food: Shotsy is not a calorie tracker, so if you also want to know whether today's meals were protein-dense enough, you end up running a second app alongside it.

Pep is another medication-focused option that leans into reminders, dose schedules, and progress tracking with a friendly tone. It is a solid companion for staying on schedule and watching your trend line. Like Shotsy, its center of gravity is the shot rather than the plate, so detailed nutrition and photo logging are not where it competes.

MeAgain sits in the broader weight and wellness tracking space, bringing habit and progress features that some GLP-1 users like for the bigger picture. It can be a comfortable home base for trends and check-ins. The trade off is depth on the two GLP-1 specifics that matter most day to day, fast food logging tuned for a small appetite and tight integration between your dose and your meals.

Across these tools the recurring theme is the split. Injection trackers are strong on the medication and weak on food, while general calorie counters are strong on food and blind to the medication. For someone on Ozempic or Mounjaro, that split means juggling two apps and never seeing the dose and the diet in one timeline, which is exactly the view a doctor asks about.

When you compare them, judge each app on four things: how fast it logs food on a suppressed appetite, whether it scores meals for protein density rather than just calories, whether it tracks your dose and side effects, and whether it keeps all of that in one place. Very few apps clear all four, and that is the gap worth closing.

Mello was built to close it. You snap a photo and the AI estimates calories and macros, then gives each meal a GLP-1 Friendly Score so you instantly know if it fits a reduced appetite. You log every injection and dose, follow side effects over time, and export a clean summary for your appointment, covering Ozempic, Wegovy, Mounjaro, and Zepbound in one app. Mello is 19.99 USD per month or 99.99 USD per year with a 3-day trial. Download Mello and scan your next meal.
