Regimen vs Shotsy: Which GLP-1 Tracker Is Right for You?
Shotsy is a GLP-1 shot log, and a good one. Regimen tracks your Wegovy, Zepbound, Mounjaro, or Ozempic the same way, then connects the dots: the stuff that actually moves your week (food noise, nausea, energy, sleep, constipation, injection-site soreness) plus bloodwork and your estimated medication-level curve, connected by built-in pattern detection so you're not scrolling through logs to figure out why a day felt off. You can also add progress photos so you've got a real record of the journey, not just a weight graph, plus other compounds whenever you want. The medication-level curve Shotsy currently gates behind premium is free here.
Quick Answer
Choose Shotsy if a GLP-1 shot log plus built-in food and water logging is what you want, and you’d like the app that has been around longer. Choose Regimen if you want the app to interpret your week for you, GLP-1 daily markers, side effects, bloodwork, and medication-level curves, all connected by built-in pattern detection, and to keep tracking other compounds later if your routine changes.
More than a shot log
Track your GLP-1 alongside other peptides and supplements, with medication-level curves built in.
Shotsy logs your shot. Regimen logs the shot and connects the dots across your week. Track the markers that actually shape a GLP-1 week (food noise, nausea, energy, sleep, constipation, injection-site soreness) alongside your dose, and built-in pattern detection watches those markers and shows you the pattern it finds: your food noise tends to creep back around day 5, or your energy dips as the dose wears off. That’s what “understanding your journey” means here, not more charts.
And if your routine changes later (a peptide for recovery, TRT, or a supplement you want to measure) it lives in the same app, with its own schedule and reminders. You’re not stuck in a single-purpose tool the day your stack changes.

Why Regimen wins
It connects the dots across your week. Regimen turns your GLP-1 daily markers and dose history into an actual pattern you can act on, not another chart to interpret.
Depth where it matters. 50+ GLP-1-native markers, detailed side-effect tracking, and bloodwork, all mapped to your Wegovy, Zepbound, Mounjaro, or Ozempic dose history.
Medication-level curve, free. Free for your first compound in Regimen.
It grows with you. Add other peptides, TRT, or supplements later without switching apps.
Where Shotsy is strong
It has been around longer. If a GLP-1 is all you track, it’s a reasonable choice.
Built-in food and nutrition logging (calories, protein, water), which Regimen doesn’t do. If you want your shot log and your food log in the same app, Shotsy has that.
Coming from Shotsy
The thing most people worry about when they switch is losing months of logged doses. You will not.
Regimen has a one-step Shotsy import. Your dose history comes across, so the timeline you have already built keeps going instead of restarting at day one. That matters more than it sounds: the medication-level curve, the weight trend and the patterns Regimen finds all get better the longer the history behind them is, and starting over costs you that.
“I’m split-dosing and wanted a program that would allow me to enter specific days for dosing, which Shotsy doesn’t do, so I asked Google AI to compare other programs, reviewed Glapp and Regimen and MeAgain, and it looks like Regimen does what I want.” — Holly, switched from Shotsy, August 2026
“I love that we can add our full stack on this app… The app is easy to use, easy to track and I will not be renewing my Shotsy subscription after this.” — xteanee, App Store
If you are looking for a Shotsy alternative because you have started tracking something alongside your GLP-1, a peptide, testosterone or supplements, that is the case Regimen is built for, and it is the one Shotsy does not cover.
Which app should you use?
Choose Regimen if you want the app to interpret your week for you (pattern detection on your GLP-1 daily markers, side effects, bloodwork), you want the medication-level curve without paying extra, or you might track other compounds later.
Choose Shotsy if a GLP-1 is the only thing you track, you want the app that has been around longer, or you specifically want built-in food logging.

Which is better, Regimen or Shotsy?
Shotsy is a GLP-1-only tracker and it's a solid shot log.

No. Shotsy focuses on weight and basic logging. Regimen adds 50+ GLP-1-native daily markers (food noise, nausea, energy, sleep, constipation, injection-site soreness and more), detailed side-effect tracking, and bloodwork, all mapped to your dose history, with built-in pattern detection connecting the dots.

No, Shotsy is GLP-1-only. Regimen tracks your GLP-1 plus any other peptides or supplements in one app.
