MyPep is the GLP-1 tracker for shots and pills. One simple place to track every shot and everything in between. Use MyPep with Ozempic®, Wegovy®, Mounjaro®, Zepbound®, Rybelsus®, Saxenda®, Trulicity®, compounded semaglutide or tirzepatide, and other weekly or daily injection routines. GLP-1 tracking should not feel like another job. There is shot day, low appetite, protein and water goals, side effects, weight stalls and progress photos. MyPep brings the routine together with less mental load and one place to stay on top of what matters. TRACK SHOT DAYS AND PILLS • Log GLP-1 shots and oral pills in one tap • Weekly or daily schedules with shot reminders • A shot-day checklist with times built around your shot • A countdown to your next shot • Doses left in your pen, with a heads-up before you run out PROTEIN, FIBER AND WATER • Daily protein, fiber and water goals with quick-add portions • Track what matters most when appetite is low • Log steps and workouts to help protect muscle SIDE-EFFECT TRACKER • Rate nausea, fatigue, food noise, constipation, reflux and more on a 0–10 scale • Choose which symptoms you track • Log today or fill in past days • Keep clearer notes to discuss with your healthcare provider INJECTION SITES • Pick the site on a body map when you log a shot • See which areas you used recently so you can rotate PROGRESS BEYOND THE SCALE • Weight trend, goal progress, BMI and estimated goal date • Private progress photos • Full shot history on a calendar WHY MYPEP Food apps focus on calories. Reminder apps focus on alarms. MyPep is built for the GLP-1 routine itself: shots, sites, protein, fiber, water, side effects, weight and photos together. PRIVATE BY DEFAULT • Sign in with Apple.

Peptrend draws the trend line under your weigh-ins. Body weight swings several pounds a day on water, food, and salt. A single reading is a noisy sample of a slow-moving signal, so Peptrend fits a smoothed line through your data and shows what is happening underneath it. THE TREND Choose how the line gets drawn: exponentially weighted moving average, the Hacker's Diet filter, a Kalman filter, Hull, DEMA and TEMA, rolling median, Kaufman's efficiency ratio, and more. Swipe between methods and watch the same weigh-ins redraw. Import your history from Apple Health or enter readings by hand. DOSES Log GLP-1 doses, injected or oral, and see an estimate of how much is still circulating based on that medication's half-life. Oral tablets are modeled with their own absorption, so a 14 mg tablet is not charted as 14 mg in your bloodstream. Moving to a different medication, or taking two at once? Each one keeps its own half-life and its own line on the chart. Log vials, reconstitution, injection-site rotation, and titration over time. GOAL PROGRESS Set a target weight and a date, or a steady weekly rate. A waterfall chart breaks progress down week by week, colored by the dose you were taking, so the weeks that moved are easy to tell apart from the ones that did not. ATHLETE MODE If you train, switch on Athlete Mode and a new tab charts what your watch already records in Apple Health: VO2 max, heart rate variability, resting and walking heart rate, cardio recovery, blood oxygen, exercise minutes and more. Each line is colored by the dose you were taking, so you can see the two side by side. Peptrend reads those numbers and never writes to them, and it does not claim that one causes the other. PRIVACY No account, no analytics, no advertising, no network calls. Weigh-ins live on your device and in your own private iCloud database, which we cannot read. The privacy manifest declares no collected data and no tracking. PEPTREND PRO Logging your weight and doses is free, and stays free. Pro adds the full set of trend methods, projections, energy-deficit estimates, the goal waterfall, and Athlete Mode. Seven days free, then $12.99 per month, $69.99 per year, or $99.99 once. Peptrend is not a medical device and does not diagnose, treat, cure, or prevent any medical condition, and it does not provide medical advice. Circulating-dose figures are estimates derived from published half-lives, not measurements of your blood. Decisions about your treatment belong with your prescriber.

Verdict

The call

The clearest difference is update cadence: MyPep at every 2 days against Peptrend's every 2 weeks. MyPep also leads on ratings volume (30 vs 2). Peptrend's advantage is rating (5.0 vs 4.7) and iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. MyPep sells 4 in-app purchases, starting at $9.99 per month and Peptrend sells 3 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings
