Shotsy vs JabKeeper: which GLP-1 tracker should you use?

If you're on a weekly GLP-1 injection such as Mounjaro, Wegovy, Zepbound or Ozempic, you've probably come across Shotsy. It launched in 2024, and by September 2026 it had a 4.8 rating from about 32,000 ratings on the US App Store. JabKeeper is newer and deliberately smaller, built around one idea: a private, offline diary for a single weekly injection.

They're both good at the core job of remembering your doses. They make very different choices about subscriptions, sync and scope, though, and those choices decide which one suits you. This comparison sets them side by side, including the areas where Shotsy is the stronger app.

Shotsy vs JabKeeper at a glance

In JabKeeper, the weight, side-effect, food, Apple Health and Calendar features are part of the one-time lifetime unlock. For Shotsy, the table notes which features need Shotsy+. The rest are in its free version or aren't marked as paid on its listing.

Price: subscription or one-time purchase

This is the biggest practical difference. Shotsy's free version is generous. According to Shotsy's own free vs Shotsy+ page, it includes shot logging, dose reminders, injection site rotation, side-effect logging and weight tracking with charts, with no time limit. The Shotsy+ subscription adds the estimated medication level chart, Apple Health sync and a medication-levels widget.

Apple doesn't show which price a new subscriber will be offered. On 14 September 2026, though, the US App Store listed Shotsy+ monthly options from $9.99 to $19.99 and yearly options from $39.99 to $59.99. The UK listing showed £7.09 to £19.99 a month and £29.99 to £39.99 a year. We found no lifetime option.

JabKeeper's free version is smaller: two dose records, reminders, the countdown and site rotation. A single $9.99 in-app purchase unlocks unlimited history, weight and goals, side effects, food, Apple Health and Calendar, permanently.

So the honest summary is this. If Shotsy's free features cover what you need, Shotsy costs nothing. If you want medication levels or Apple Health sync, Shotsy+ is an ongoing cost. JabKeeper is a small one-off payment for everything it offers, but it offers less. Our guide to what GLP-1 tracker apps cost runs the same maths across more apps.

Features compared

Dose logging and schedules

Both apps log the date, time, dose, injection site and notes, and both remind you when a dose is due. Shotsy covers a much wider range of treatments. Its listing names Ozempic, Wegovy (including the Wegovy pill), Mounjaro, Zepbound, Rybelsus, Saxenda, Victoza and Trulicity. It also supports custom medicines and several medicines at once, each with its own schedule. That makes it the clear choice if you take a daily GLP-1 tablet or combine treatments.

JabKeeper is narrower by design. You pick one weekly injection (Mounjaro, Wegovy, Zepbound, Ozempic or another weekly injection) and your prescribed strength from preset options. Logging then takes a few taps. It reminds you the day before at your usual injection time and again on the day. It never suggests a dose or a change.

Estimated medication levels

Shotsy+ includes a chart that estimates how much medication is in your system over time, for semaglutide, tirzepatide and some other GLP-1 medicines. Some people find it motivating. Keep in mind it's a model-based estimate, not a blood test. JabKeeper doesn't offer anything similar and focuses on what you actually recorded.

Weight, food and side effects

Both track weight with BMI and a goal. Shotsy supports stones and pounds, adds a maintenance mode, and logs many more metrics: water, carbs, fibre, body composition and blood glucose. JabKeeper records weight in kilograms or pounds. It adds a weekly pace and two goal-date estimates, one from your plan and one from your recent trend. Its food log is intentionally simple: calories and protein, with daily goals.

For side effects, Shotsy lets you add custom symptoms and chart them. JabKeeper offers seven common symptoms with a labelled 1–5 severity scale and a note. It shows how many days after your last dose each one started, and gives a four-week summary. When you log a severe entry, it suggests contacting your prescriber.

Apple Health, calendar, widgets and export

Shotsy's Apple Health connection needs Shotsy+ and imports data such as weight, calories, protein and water. JabKeeper's is included in the unlock: it reads and saves body weight and writes the calories you log. It also adds your next injection to iPhone Calendar with an alert. Shotsy offers home-screen widgets and exports to CSV, PDF and a JSON backup. JabKeeper has neither widgets nor export at the moment. If you regularly share records with a clinic, that counts in Shotsy's favour.

Privacy and where your data lives

Neither app declares any data used to track you, and neither declares data linked to your identity. The differences are in the details:

Shotsy's privacy policy also explains that US iPhone users may contribute anonymous "experience data" for trend analysis, and that you can opt out. It says Shotsy doesn't sell data or share it for targeted advertising.

JabKeeper takes the strictest possible approach: the developer never receives your diary at all. The trade-off is real. With no sync or backup, your JabKeeper history doesn't move to a new iPhone, and it's gone if you lose your phone or delete the app. Shotsy's iCloud sync avoids that. Our GLP-1 tracker privacy guide explains how to read these labels for any app.

Which should you choose?

If you're switching, note that JabKeeper can't import another app's history. Export a copy from Shotsy for your records, then set up JabKeeper with your current medicine, dose and most recent injection. Still weighing things up?
