Shotsy has earned a strong reputation as the default visual shot logger for brand-name GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound. Its sleek iOS widgets and estimated blood-level graphs made injection day simpler for early adopters.
However, over the past year, two massive shifts have triggered a wave of patients seeking alternatives:
- The Subscription Paywall: Features that users expected to be free — such as Apple HealthKit synchronization, long-term half-life curves, and injection site rotation — are locked behind a recurring $19.99/year ($3.99/month) subscription.
- The Compounded Dosing Reality: With ongoing FDA shortages and high brand copays, more than 50% of US patients now receive compounded semaglutide or tirzepatide from 503A/503B pharmacies (Lavender Sky, Mochi, Henry Meds). These medications are drawn using insulin syringes marked in units from vials of varying concentrations (e.g., 2.5 mg/mL, 5 mg/mL, 10 mg/mL). Shotsy is built for fixed-milligram brand pens, leaving compounded patients to guess mental math that risks severe dosing errors.
• Pick GLPme if you want free core tracking with zero subscription, take compounded medication dosed in units, want 100% on-device privacy, or need to track food noise & lean muscle mass.
• Pick DoseDiary if you only want a minimalist, low-friction injection calendar and do not need pharmacokinetic curves.
• Pick Apple Health + Notes if you want a complete DIY zero-cost stack and don't mind manually typing your logs.
• Stay with Shotsy only if you exclusively take branded pens (Ozempic/Zepbound), rely heavily on Apple Watch complications, and are happy paying $19.99 every year.

The 3 Big Reasons Patients Are Leaving Shotsy
1. The $19.99/Year Subscription Fatigue
GLP-1 medications are already financially taxing. Whether paying $1,000+/month out of pocket for brand Wegovy or $200–$350/month for compounded tirzepatide via telehealth, adding a continuous software tax just to view when your injection reaches peak concentration is frustrating. Users downloading Shotsy often find themselves blocked by paywalls for essential views like 90-day medication plots and HealthKit data syncing.
2. The Compounded Syringe Math Dilemma
The FDA has repeatedly warned patients about compounding errors where individuals accidentally injected 5 to 20 times the prescribed dose because they confused syringe units (a volume measure) with milligrams (a drug mass measure). Shotsy was designed around single-dose brand pens that click into place. When patients with compounded vials try to enter "37.5 units" or calculate what volume to draw from a 10 mg/mL vial for a 2.5 mg dose, Shotsy offers no native support. GLPme was built specifically with dual support: brand pen milligrams AND compounded syringe units with automatic concentration conversion.
3. Privacy and Medical Cloud Storage
Weight loss and metabolic health history is highly sensitive personal health information (PHI). Many users do not want their medication schedules, body weight, and symptom logs stored on third-party cloud servers. Local-first architectures, where data remains encrypted on your personal iPhone and inside Apple HealthKit without requiring a cloud username or password, provide vastly superior security.

On-Device Privacy
1. GLPme — Best Overall for Compounded Dosing & Clinical Context
GLPme was engineered to solve the exact problems that pure shot loggers overlook: managing compounded vial arithmetic, tracking return of food noise, and preventing sarcopenic lean muscle loss.
Unlike single-purpose trackers that treat injection day as a standalone event, GLPme connects your medication timeline directly to how your body responds. It models pharmacokinetic elimination curves for both semaglutide (7-day half-life) and tirzepatide (5-day half-life), records daily food noise intensity in 10 seconds, and pairs with your weight to ensure you aren't losing dangerous amounts of lean muscle tissue.
Where GLPme Wins:
- Zero subscription paywalls: Core dose logging, Apple Health sync, and half-life decay curves are completely free.
- Native Compounded Math: Automatically converts vial concentrations (e.g. 5 mg/mL, 8 mg/mL, 10 mg/mL) to U-100 syringe units.
- Food Noise Tracking: Daily 10-second check-in to monitor cravings and appetite suppression before regain occurs.
- 100% Private: Operates locally on your iPhone. Zero third-party account signups or cloud data harvesting.
- Doctor Visit Summary: Generates clean clinical timelines ready for your prescriber.
Where GLPme Is Weaker:
- iOS only (no native Android app yet; Android users can use GLPme's free browser calculators).
- Fewer gamified confetti badges than consumer fitness apps.

Clean Calendar
2. DoseDiary — Best for Simple Chronological Notes
DoseDiary provides a clean, streamlined diary interface. If you simply want a calendar view showing which day you took your shot and what side effects you felt in a text journal, DoseDiary is straightforward and approachable.
Where DoseDiary Wins:
- Simple calendar-first layout that looks like a clean daily planner.
- Easy free-text note logging for quick subjective thoughts.
- Slightly lower annual subscription price than Shotsy.
Where DoseDiary Is Weaker:

4. Apple Health + Happy Scale — Best Zero-Cost DIY Stack
If you don’t want to download any dedicated medication app, you can build a reliable free stack using native iOS tools. In Apple Health, you can set up a weekly recurring medication for Ozempic or Mounjaro, while logging your daily weights in Happy Scale (which uses moving mathematical averages to eliminate emotional scale anxiety).
Where DIY Wins:
- Zero recurring costs forever.
- Unrivaled Apple ecosystem integration and encrypted iCloud backup.
- Happy Scale has the best moving-average weight trend math in the industry.
Where DIY Is Weaker:
- Fragmented experience: Requires checking 3 different apps to see medication, weight, and symptoms.
- No pharmacokinetic decay curves to visualize when the medication is clearing your system.
- No automated doctor visit reports.

5. Shotsy — When It Still Makes Sense
We believe in honest recommendations: Shotsy remains a solid choice for a specific user profile. If you are taking standard brand-name autoinjector pens (such as standard 2.4 mg Wegovy or 15 mg Zepbound), heavily rely on Apple Watch complications to log shots from your wrist, and don't mind the $19.99/year subscription, Shotsy has a very refined interface.
Where Shotsy Excels:
- Polished iOS lock-screen and home-screen interactive widgets.
- Native Apple Watch companion app.
- Smooth visual aesthetics for brand pen titrations.
Where Shotsy Falls Short:
- Mandatory $19.99/year subscription for Apple Health sync and advanced curves.
- No native U-100 syringe unit math for compounded vials.
- Ignores food noise, lean mass preservation, and comprehensive clinician reporting.
How to Switch from Shotsy to GLPme in 3 Minutes
Switching trackers does not mean losing your hard-earned titration history. Here is the easiest migration path:
- Ensure Apple HealthKit Sync Is On: In your existing Shotsy app, verify that your previous injections were written to Apple HealthKit.
- Download GLPme: Install GLPme free from the App Store.
- Grant HealthKit Permissions: When prompted, allow GLPme to read your medication and weight history. Your historical injection timeline will populate automatically.
- Select Your Medication Format: Choose whether you are on a branded pen (mg) or a compounded vial (mg + concentration + syringe units). GLPme will handle all future conversions automatically.
Frequently Asked Questions
What is the best free alternative to Shotsy?
GLPme is currently the top-rated free alternative on iOS. It provides core injection tracking, pharmacokinetic elimination curves, food noise check-ins, and clinician PDF exports without locking features behind a $19.99/year subscription paywall.
Does Shotsy work with compounded semaglutide or tirzepatide?
Not natively. Shotsy is designed around pre-filled brand pens with fixed milligram dosages. It does not calculate syringe units on U-100 insulin syringes or adjust for custom vial concentrations (such as 2.5 mg/0.5 mL or 10 mg/mL). GLPme was built specifically with native compounded vial math to prevent dangerous dosing mix-ups.
Why does Shotsy charge a subscription?
Shotsy relies on an annual subscription business model ($19.99/year or $3.99/month) to fund ongoing server infrastructure and maintenance. While paid models are common, GLPme utilizes an on-device architecture that eliminates expensive cloud server overhead, allowing us to keep core clinical tracking completely free.
Can I track food noise in a GLP-1 app?
Most standard trackers overlook food noise completely. GLPme includes a dedicated 10-second daily check-in that tracks cravings and appetite suppression trends alongside your medication curve, helping you and your clinician identify when a dose is wearing off early.
Is my medical data kept private in GLPme?
Yes. GLPme is built on a 100% on-device privacy model. Your health data stays on your personal device and inside your encrypted Apple Health database. You do not need to register an account, and we never collect, track, or sell your personal health records.
