Disclosure: We make GLPme. This page still names where other apps win. Shotsy remains the strongest pure dose logger for many people. If you only need injection logging, start there. Rankings are by job-to-be-done — not by who paid us (nobody did).
Choose GLPme if you want an all-in-one private iOS companion that converts compounded syringe units to mg, tracks daily protein to protect muscle mass, journals food noise, and plots half-life decay without an expensive subscription.
Choose Shotsy if you strictly want a clean Apple Health-integrated shot log for brand-name pens and do not mind paying $19.99/yr for level charts.
Choose Apple Health + Notes if you want 100% zero third-party software and are willing to calculate compounded syringe units and protein by hand.
People on GLP-1 medications rarely search for “a wellness suite.” They want to remember the shot, quiet food noise, hit protein, and walk into a twelve-minute appointment with something better than memory. No single app owns every job yet — which is why the real answer is usually a stack, and why an honest comparison beats a fake “#1” list.
Quick picks by job
Shotsy
Mature dose history, sites, and medication-first UX. Default community pick when injections are 90% of the need.
Cronometer / MFP
Deep catalogs and macros. Weak on medication context and food noise as a first-class signal.
Happy Scale
Quiets daily scale noise. Does almost nothing else for a GLP-1 journey.
Apple Health + Notes
You own the data — and the maintenance burden of the system.
GLPme
Built for the whole GLP-1 arc: compounded syringe units conversion, protein target math to prevent muscle loss, food noise tracking, half-life blood level curves, and doctor-ready summaries. Free core on iOS.

App-by-app notes
Shotsy
Recommend when the job is “did I take the shot, on what dose, in which site?” Years of polish; community defaults here for a reason.
Skip or pair when food noise is returning, protein is slipping, you are pausing or stretching doses, or you need a one-page clinician story.
If pure medication logging is your only need, we recommend Shotsy over GLPme. Winning trust beats winning every download. However, if you are looking to avoid the $19.99/year subscription or take compounded semaglutide in syringe units, explore our in-depth teardown: 5 Best Shotsy Alternatives (2026).
DoseDiary
Strong when progress is visual — photos, weight, food in a diary rhythm. Weaker when the journey becomes pause, restart, switch, and maintenance rather than a continuous “losing” diary.
MeAgain
Broad wellness and coaching can feel more supportive than a logbook. Tradeoff is sharpness: GLP-1 maintenance and clinician-ready structure are not the center of gravity.
Pep AI
Closer to peptide protocols than mainstream prescribed semaglutide/tirzepatide maintenance. Excellent for that audience; most people need a simpler daily companion.
MyFitnessPal & Cronometer
Still the deepest catalogs. Use when macros and protein grams are the bottleneck. Do not expect dose days, food-noise scores, or appointment prep. Pair with a shot logger if medication is also in play.
Happy Scale
Turns noisy daily weights into a trend you can live with. Keep it if the scale is psychologically loud. It will not replace medication or appetite tracking.
Apple Health + Notes
Perfect until the system collapses under its own templates. Most DIY stacks die when life gets busy — exactly when maintenance data matters most.
GLPme (us)
Built for the gap the stack creates: one timeline for medication context, food noise, protein, side effects, weight, and a clinician summary. Maintenance and transitions are product goals, not afterthoughts.
Where we lose: Shotsy on pure injection polish; MFP/Cronometer on food databases; Happy Scale on weight-only smoothing; Android users; longevity and review volume of older apps.
Where we fit: you already juggle three or four tools; food noise and protein matter as much as the shot; you want maintenance after goal weight and cleaner appointment prep. Details on the product page.
The four-app stack problem
Across GLP-1 communities the pattern repeats: shot app + food app + scale app + Notes. Each tool is rational alone. Together they create missing context — you cannot see that food noise rose the week protein crashed after a dose change unless one timeline holds all four signals.
The real decision is not “is app X #1?” but “which job is broken in my stack?”
- Remembering shots → Shotsy
- Macros → Cronometer / MFP
- Scale anxiety → Happy Scale
- Integration + food noise + maintenance + doctor story → GLPme or careful DIY
What almost no app does well yet
- Maintenance as the product — not a settings toggle after goal weight.
- Food noise as a first-class metric — ten-second check-ins, not only calorie diaries.
- Clinician-ready output — usable in a short visit.
- Normal dose states — stretch, taper, pause, restart, switch without treating them as errors.
- True consolidation — medication + appetite + protein + weight + notes without four logins.
Longer research note: what existing apps still miss.
How to choose in five minutes
- List every app and note you open in a normal week.
- Circle the job that fails most often (forgot a shot? no protein visibility? dread the scale? blank at the doctor?).
- Pick the specialist for that job first.
- Only then ask whether one companion can retire two or more tools.
- If you switch, export or screenshot history first — data portability is uneven.
FAQ
What is the best app for logging Ozempic or Mounjaro shots?
For pure shot logging, Shotsy is still the safest default. Add other tools when food, protein, or appointments become the bottleneck.
What is a good Shotsy alternative?
There is no single clone, but several strong alternatives depending on your needs. For compounded vial unit conversions, food noise check-ins, and free core tracking without a $19.99/year subscription, see GLPme on iPhone. For simple photo diary logging, consider DoseDiary. For weight smoothing without medication data, Happy Scale is standard. See our dedicated guide: 5 Best Shotsy Alternatives (2026).
Is there an app for food noise on GLP-1?
Most trackers still ignore food noise as a dedicated signal. GLPme treats it as a first-class check-in. Some people approximate it in Notes with a daily 1–10 score.
Do I need a paid app?
Not always. Apple Health + Notes is free. Many freemium trackers work at the free tier for basic logging. Pay when a feature changes a weekly decision — clearer protein, better trends, or appointment prep.
Who wrote this and why should I trust it?
GLPme publishes this page and discloses ownership of one listed product. We recommend competitors where they are stronger. Prices and features change; re-check store listings before you buy. Educational software commentary, not medical advice.
Free tools, no app required
If you only need one answer rather than a whole tracker, these are free and instant.
- Semaglutide unit calculator Compounded mg to syringe units
- Tirzepatide unit calculator Compounded mg to syringe units
- Titration schedule Every dose step and the date it is due
- Missed a dose What the label says to do
- Vial supply calculator When you run out, when to reorder
Tired of the four-app stack?
GLPme is one timeline for medication context, food noise, protein, side effects, weight, and doctor-ready notes. If you only need a shot log, use Shotsy. If you need the layer around the shot, try GLPme.
