GLP-1 Tracker vs Shotsy

We publish GLP-1 Tracker, listed on the App Store as GLP-1 Weight Loss Shot Tracker. Treat this page as a comparison written by one side, because it is. What we can promise is that nothing here is speculation: every feature is taken from each app's own App Store description, every privacy claim from its App Store label, every figure from Apple's public listing data, all read on September 19, 2026. Where Shotsy's listing does not mention something, we say it does not mention it, not that Shotsy cannot do it.

For our own app we can go one step further, because we have the source: every feature we credit ourselves with is in version 1.0.3, released on September 16, 2026, and was checked there rather than in the marketing copy.

Neither app is a medical device, and neither should tell you how much to take. Both listings say so.

Shotsy, listed as Shotsy GLP-1 Tracker: 32,080 US ratings at 4.84, version 3.3.9 updated September 15, 2026, first released May 29, 2024, 17 languages, requires iOS 18, also on Android, free with in-app purchases.

GLP-1 Tracker, listed as GLP-1 Weight Loss Shot Tracker: version 1.0.3 released September 16, 2026, first released May 28, 2026, 11 languages, iPhone and iPad, requires iOS 17, free with an optional Pro subscription. Ratings are counted per storefront: 308 in Mexico at 4.91, 19 in Brazil, 16 in the United States, 362 in total across the storefronts we checked.

Read that honestly and two things are true at once. Shotsy has a two-year head start and a sample of ratings no new app can match. And the comparison a reader actually needs is not between the two rating counts, which measure age and reach, but between what each app will do on the day of the shot, which is what the rest of this page is about.

The injection itself. Shotsy's listing documents logging a dose with a single tap, which ours does too, with a difference in what gets logged: GLP-1 Tracker records the site on a body-map picker, so the rotation history is there when the next shot is due, and it counts the doses left in your pen. Shotsy's listing mentions neither sites nor supply.

The body. Both apps chart weight; ours also charts BMI, tracks eight body measurements from neck to calves, and keeps progress photos with a side-by-side compare view. Shotsy's listing does not mention measurements or photos.

Food. Shotsy imports calories, protein and water from Apple Health. GLP-1 Tracker logs food in the app, against four meal slots, with calories, protein, fiber and water, from a curated database of 5,466 foods across 12 markets, by barcode, from your own saved foods, by hand, or by describing, speaking or photographing a meal. On a week when appetite has vanished and protein is the whole problem, logging in the app rather than importing from elsewhere is the difference between a number and a plan.

Side effects. Both listings document side-effect logging; ours adds red-flag warnings when a logged symptom is one that needs medical attention, links symptoms to meals, and shows symptom timing against the dose day.

Outside the app. GLP-1 Tracker ships seven Home Screen widgets, including a one-tap dose widget, a medication-level widget and a streak, a Lock Screen Live Activity counting down to the next shot, a second one for the day's nutrition, and two Control Center buttons. Shotsy's listing does not mention widgets or Live Activities.

The assistant. Otis works from a compact summary of your own log, can pull up your shot history, weight trend, nutrition or side effects, draw a chart, and log a dose, a weight, a meal, a symptom or a walk when you ask. Shotsy's listing does not mention an assistant.

The appointment. The PDF export puts doses, the weight chart, side effects, measurements and photos into one document. Shotsy's listing does not mention an export.

And iOS 17. Shotsy requires iOS 18; GLP-1 Tracker runs on iOS 17, which keeps an older iPhone in the running.

The privacy label. As of September 19, 2026 Shotsy's App Store label declares no data used to track you and nothing linked to your identity: only health and fitness data, user content, usage data and diagnostics, all not linked to you. Ours declares purchases, identifiers and usage data both for tracking and linked to your identity, and declares no collection of health and fitness data. Both apps keep your log on your device and sync it through your private iCloud, but if the label is your deciding factor, Shotsy's is cleaner and that is simply true.

Android. Shotsy has a Google Play listing. We are iPhone and iPad only, with no web version.

Languages. Shotsy ships in 17 languages to our 11.

Several medications at once. Shotsy documents multiple simultaneous medications with separate schedules, and names nine medications including Victoza, Trulicity and retatrutide. GLP-1 Tracker version 1.0.3 has a catalog of 17 medications and allows two regimens to be active at once, but Shotsy's listing is the more explicit about running several schedules side by side, and if you take a GLP-1 alongside a second compound that is the sentence to weigh.

Track record. On the App Store since May 2024, updated on September 15, 2026, 32,080 US ratings. Shotsy also publishes a named Chief Science Officer, Eric Perakslis, PhD, formerly of the US FDA. We have no equivalent credential and pretending it does not matter would be silly.

Medication levels. Both apps estimate medication levels from logged doses. Shotsy's listing names four compounds for its curves; ours draws the curve and a forecast line for every catalog entry with published pharmacokinetics. Call this one even, and read both curves as estimates, never as measurements.

Both listings describe on-device storage with private iCloud sync. Shotsy states that your data is securely stored on your device and synced across your devices with Apple's private iCloud, and that it never sells your data. GLP-1 Tracker stores your log on your device and, with iCloud sync on (the default), in your own private iCloud database, which we cannot read; it needs no account, shows no ads and never sells your data. One nuance we owe you: when you ask Otis a question, the app sends a compact summary of your log, never the raw entries, to answer it, and that conversation is not stored on our side. Shotsy's listing does not describe an assistant, so there is no equivalent to compare.

Apple states on every product page that it has not verified any developer's privacy label, so read both labels as what each developer says about itself, and read this page the same way.

Both apps are free to download and both list in-app purchases, so both are a free tier plus an optional subscription. Shotsy's listing does not say what sits on each side of its line. Ours, as of version 1.0.3: the tracking is free, meaning doses and injection sites, pen supply, reminders, the Lock Screen countdown and every widget, weight, BMI and the eight measurements, progress photos, the side-effect log and its red-flag warnings, the medication-level estimate and forecast, food logging from the database, by barcode, from your own foods or by hand, the weekly recap, and the doctor-ready PDF. The optional Pro subscription adds the AI features beyond a free allowance: parsing a meal you describe, speak or photograph, per-meal insights, and Otis's chat beyond the free messages.

Pick GLP-1 Tracker if you are on iPhone and you want one app to hold the shot, the site, the pen, the scale, the tape measure, the photos, the food, the side effects and the appointment, with a countdown on the Lock Screen and an assistant that knows your log. That is what it is built for and it is where its listing is broader than Shotsy's.

Pick Shotsy if you are on Android, if you take more than one medication on separate schedules, if the privacy label decides it for you, if you want one of its 17 languages that we do not ship, or if you want the reassurance of a two-year record and thirty thousand ratings. Those are real reasons and we would rather you choose well than choose us.
