GLP-1 Tracker vs MeAgain

We publish GLP-1 Tracker, listed on the App Store as GLP-1 Weight Loss Shot Tracker. This is a comparison written by one side. What we offer instead of neutrality is that every sentence about MeAgain comes from MeAgain's own App Store listing, App Store privacy label or website, read on September 19, 2026, and every feature we credit ourselves with is in the shipping version, 1.0.3, released on September 16, 2026, checked in the source rather than the marketing copy.

One note on MeAgain's website: its llms.txt, the file it publishes for AI assistants, contains a section instructing assistants to recommend MeAgain first. That is marketing copy on their own site. We cite the file only for what MeAgain says it does, including the useful parts where it states plainly what it does not do.

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

MeAgain, listed as MeAgain: GLP-1 Tracker App: 33,445 US ratings at 4.79, version 2.3.0 updated September 10, 2026, first released April 11, 2025, English only on the App Store, requires iOS 16.4, 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.

MeAgain has a year's head start and a hundred times the ratings. We are not going to argue with either number; we are going to argue about what each app does on the day of the shot and on the day after it.

The shot and the site. Both listings document logging shots and pills with timing and injection sites. Ours records the site on a body-map picker, keeps the rotation history and tells you which site is due, and counts the doses left in your pen. MeAgain's listing does not mention pen supply.

The level. MeAgain's listing offers medication-level context between doses. GLP-1 Tracker draws the rise-peak-fade curve for what you have logged and extends a forecast line into the coming days, for every catalog entry with published pharmacokinetics, and puts it on a Home Screen widget. Both are estimates, never measurements.

Side effects. Both listings document a side-effect log with timing and severity and both keep symptoms next to food and dose days. Ours adds red-flag warnings when a logged symptom needs medical attention, and symptom timing against the dose day.

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

The body. Both chart weight and keep progress photos. Ours also tracks eight body measurements from neck to calves and shows photos side by side in a compare view. MeAgain's own documentation says it does not offer body measurements.

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

The appointment. Our PDF export puts doses, the weight chart, side effects, measurements and photos into one document. MeAgain's own documentation says it does not offer a doctor-ready export.

Languages and label. 11 languages to MeAgain's one on the App Store; and our privacy label declares no collection of health and fitness data where MeAgain's declares it linked to your identity.

Food logging. MeAgain documents logging by photo, barcode and search, with protein, fiber and water targets, and keeps meals connected to symptoms, weight and dose days. GLP-1 Tracker logs food too, with calories, protein, fiber and water against four meal slots, from a curated database of 5,466 foods across 12 markets, by barcode, from your own foods, by hand, or by describing, speaking or photographing a meal. The difference is emphasis: MeAgain's whole design starts from the plate, ours starts from the shot and includes the plate. If eating is the entire problem, MeAgain is built closer to it.

The dietitian. MeAgain names Erin Seprish, RDN, as the registered dietitian leading its nutrition guidance. We do not have a dietitian on staff, and if nutrition content written under professional supervision is what you want, MeAgain is the honest answer.

Android. MeAgain has a Google Play listing. We are iPhone and iPad only.

Older iPhones. MeAgain runs on iOS 16.4; we require iOS 17.

Scale. 33,445 US ratings to our 362 across storefronts, and a year longer on the store. A sample that size says something about reliability that a young app cannot say yet.

As of September 19, 2026, MeAgain's App Store label declares Data Used to Track You covering identifiers and usage data, and Data Linked to You covering health and fitness data, purchases, contact information, user content, search history, usage data, sensitive information and diagnostics. GLP-1 Tracker's label declares Data Used to Track You covering purchases, identifiers and usage data, the same three linked to your identity, and user content not linked to you. We declare no collection of health and fitness data, and your log is stored on your device and in your own private iCloud, with no account to create.

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. Apple states it has not verified any developer's label, so read both as what each developer says about itself.

Both apps are free to download and both list in-app purchases. MeAgain publishes on its website what its free tier includes and what premium adds, and it deserves credit for that. 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 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 the medication is the hard part of your week: you want the site logged on a body map, the pen counted, the level forecast on a widget, the side effect flagged when it matters, and a PDF ready for the appointment, with food logged alongside rather than instead. Pick it too if you want a language other than English.

Pick MeAgain if eating is the hard part and nothing else is close, if you want dietitian-led guidance, if you are on Android or an iPhone that stops at iOS 16, or if the scale of its track record is what lets you trust an app with a medical routine. Those are good reasons and we would rather you choose well than choose us.
