What is Shotsy?
Shotsy has over 100,000 downloads and a 4.8-star rating, making it the most popular GLP-1 tracking app. Aja Beckett, a software engineer, built it based on her own experience using Mounjaro. It started as a side project and now has $2.25 million in VC funding.
Shotsy App Review
The app logs when you took your injection, monitors side effects over time, and tracks weight progress. The premium subscription ($49.99/year) adds medication level estimation charts showing how much GLP-1 remains in your system between injections.
Shotsy Strengths
- All-in-one tracking: Shot logging, side effect monitoring, weight tracking, and injection site rotation in one app
- Native mobile apps: Purpose-built iOS and Android apps optimized for mobile use
- Apple Health integration: Automatically imports weight, calories, protein, and water data
- Analytics: Charts showing trends, symptom correlations, and progress over time
- Active development: Large user base with regular updates and new features
- Funded team: VC backing and a Chief Science Officer, so it's likely to stick around
Shotsy Limitations
- Premium pricing: $49.99/year subscription, recently increased from $29.99 (67% price hike)
- Paywalled features: Medication level charts, a core feature for many users, require premium subscription
- Narrow scope: Only does shot tracking; no meal planning, macro tracking, or other health features
- Limited microdosing support: Not designed for users exploring split-dosing or alternative dosing protocols
- No schedule sharing: Can't generate shareable links to show your dosing protocol to others
- Data sync issues: Users report slow data loading and multi-device sync limitations
- No retatrutide focus: Limited support for the emerging triple-agonist medication
Pricing context: Shotsy's annual price jumped from $29.99 to $49.99 after their February 2025 funding round. That 67% price hike is a big reason people started looking for alternatives.
GLP3 Planner: Free Medication Level Charts
GLP3 Planner doesn't try to track every shot you take. Instead, it focuses on pharmacokinetic visualization: showing how your medication levels change over time based on your dosing schedule. The important part: this is completely free, while Shotsy charges $49.99/year for similar charts.
Why Choose GLP3 Planner Over Shotsy
Free Drug Concentration Charts
The medication level visualization that Shotsy locks behind a $49.99/year paywall is free on GLP3 Planner. See exactly how your drug levels rise and fall between doses without paying a subscription.
Microdosing Protocol Support
Explore split-dosing schedules that Shotsy doesn't support. Model twice-weekly, three-times-weekly, or daily microdosing to see how different frequencies affect your drug levels.
Shareable Schedule Links
Generate URLs with preview images to share your dosing schedule on Reddit, in Facebook groups, or with your healthcare provider. Shotsy doesn't offer schedule sharing functionality.
Retatrutide Focus
Comprehensive support for retatrutide with titration guides, dosing strategies, and educational content. GLP3 Planner was built with the emerging "GLP-3" triple agonist in mind.
Free Medication Level Visualization
This is the type of drug concentration chart that Shotsy charges $49.99/year to access. On GLP3 Planner, it's completely free.

What GLP3 Planner Doesn't Do
To be fair, GLP3 Planner isn't a direct Shotsy replacement for all use cases. Here's what it doesn't offer:
- No injection tracking: GLP3 Planner models future schedules but doesn't log actual injections you've taken
- No side effect monitoring: No diary or calendar for tracking nausea, constipation, or other symptoms
- No weight tracking: Doesn't track your weight progress over time
- No injection reminders: Won't send notifications reminding you to take your shot
- No Apple Health integration: Doesn't sync with your phone's health data
If you need comprehensive tracking, Shotsy or Glapp may be better fits. But if you primarily want medication level visualization and schedule planning (especially for microdosing or retatrutide), GLP3 Planner delivers those features free.
Shotsy vs GLP3 Planner Features
Medication Level Visualization
This is Shotsy's headline premium feature: charts showing your estimated medication levels throughout the week. Understanding where you are in the absorption, peak, and elimination phases helps predict when side effects and hunger might occur.
Shotsy: Available only with $49.99/year premium subscription. Shows semaglutide and tirzepatide concentration curves based on your logged doses.
GLP3 Planner: Free. Uses pharmacokinetic modeling to show drug concentration over time. Supports semaglutide, tirzepatide, and retatrutide with customizable schedules and microdosing frequencies.
Winner: GLP3 Planner for offering comparable visualization completely free, with additional medications and microdosing support.
Shot Tracking and Logging
Shotsy: Core strength. Log every injection with date, time, dose, and injection site. Track rotation patterns and maintain a complete history of your actual doses.
GLP3 Planner: Different approach. Plans and visualizes future schedules rather than logging past injections. Better for understanding "what if I dose this way?" than "what did I take?"
Winner: Shotsy for comprehensive injection tracking and history. If logging actual doses is your priority, Shotsy excels here.
Side Effect Monitoring
Shotsy: Calendar-based side effect logging with symptom correlation reports. Track nausea, constipation, fatigue, and other common GLP-1 side effects to identify patterns.
GLP3 Planner: No side effect tracking. The tool focuses on pharmacokinetic visualization, not symptom logging.
Winner: Shotsy for side effect monitoring. This is a feature category where Shotsy genuinely provides value that free alternatives don't match.
Schedule Planning and Microdosing
Shotsy: Designed for standard weekly dosing. Limited support for users exploring alternative dosing protocols like split-dosing or microdosing.
GLP3 Planner: Built specifically for flexible schedule exploration. Model twice-weekly, three-times-weekly, every-other-day, or daily microdosing protocols with real-time visualization of how different frequencies affect peak-to-trough ratios.
Winner: GLP3 Planner for users interested in microdosing or alternative dosing strategies.
Sharing and Collaboration
Shotsy: No sharing functionality. Your tracking data stays within the app.
GLP3 Planner: Generate shareable URLs with automatically created preview images. When you share a link on Reddit or in a message, recipients see a visual preview of your drug concentration chart before clicking. Perfect for getting feedback from communities or showing your schedule to healthcare providers.
Winner: GLP3 Planner for schedule sharing capabilities.
Free Tirzepatide Calculator Alternative
If you're specifically looking for a free tirzepatide calculator, GLP3 Planner offers comprehensive tirzepatide dose modeling without Shotsy's subscription. The calculator shows how Mounjaro and Zepbound concentrations change based on your dosing schedule, whether you're on standard weekly injections or exploring split-dosing approaches.
Unlike Shotsy's tirzepatide tracking (which requires premium), GLP3 Planner's tirzepatide dosing calculator lets you visualize drug levels at any dose from 2.5mg to 15mg. You can model titration schedules, compare weekly vs twice-weekly dosing, and see how different frequencies affect peak-to-trough ratios, all completely free.
Semaglutide Dose Calculator Comparison
For users on Wegovy or Ozempic, both Shotsy and GLP3 Planner offer semaglutide visualization, but with key differences. Shotsy's semaglutide tracking requires a $49.99/year subscription to see medication levels. GLP3 Planner's free semaglutide dose calculator shows the same pharmacokinetic curves without any cost.
GLP3 Planner also supports semaglutide microdosing protocols that Shotsy doesn't accommodate. If you're exploring daily or every-other-day semaglutide dosing (popular in some communities for managing side effects), GLP3 Planner can model those schedules while Shotsy is designed primarily for standard weekly injection tracking.
Shotsy or GLP3 Planner: Which Is Better?
Shotsy Is Worth $49.99/Year If You:
- Need comprehensive shot logging with injection site rotation tracking
- Want side effect monitoring with symptom correlation reports
- Value Apple Health integration for automatic data import

For basic tracking without installing any apps, many users simply log injections in Apple Notes and track weight through Apple Health. No charts or analytics, but completely free and private. Works best when combined with a free calculator like GLP3 Planner for visualization.
New GLP-1 Tools in 2026
Several new tools have launched in 2026, competing directly with both Shotsy and GLP3 Planner. Here's how they compare:
GLPeak.ai
Web • Free
New AI-powered GLP-1 calculator that targets compounded semaglutide and tirzepatide reconstitution. Offers a clean interface for calculating BAC water volumes and syringe units.
How it compares to GLP3 Planner: GLPeak focuses on reconstitution math only. It doesn't model drug levels over time, show accumulation, or calculate steady state. GLP3 Planner's pharmacokinetic model shows the full picture of what happens after injection, not just how to prepare the dose.
PepCalc (iOS App)
iOS • Free • 4.6 stars (169 ratings)
Mobile-first peptide reconstitution calculator. Solves for dosage, reconstitution, BAC water, and syringe units. Clean native app experience.
How it compares to GLP3 Planner: PepCalc is a reconstitution calculator, not a PK modeler. It tells you how many units to draw but doesn't show drug level curves, accumulation, or steady-state timing. GLP3 Planner does both: reconstitution math and pharmacokinetic visualization.
Peptide Vendor Calculators (Cellgenic, Prime Peptides, etc.)
Web • Free (on vendor sites)
Multiple peptide vendors now embed reconstitution calculators on their product pages. These are basic tools: enter vial size and water volume, get units per dose.
How they compare to GLP3 Planner: Vendor calculators serve one purpose: converting mg to syringe units. They exist to reduce friction before a purchase. They don't model drug levels, show half-life curves, support microdosing, or help you understand accumulation. GLP3 Planner is compound-agnostic and has no product to sell.
2026 Competitive Landscape
| Tool | Price | Reconstitution | PK Modeling | Microdosing | Retatrutide |
|---|---|---|---|---|---|
| GLP3 Planner | Free | ✓ | ✓ | ✓ | ✓ |
| Shotsy | $49.99/yr | - | Premium only | Limited | Limited |

For free tirzepatide dosing calculation, GLP3 Planner provides the most flexible option. It supports all Mounjaro and Zepbound doses (2.5mg to 15mg), shows drug concentration curves based on tirzepatide's pharmacokinetics, and uniquely supports microdosing protocols. Shotsy also offers tirzepatide tracking but requires a $49.99/year subscription for medication level charts. For basic dose planning without visualization, GLP-1 Plotter is another free option.
Is there a mounjaro half-life calculator?
GLP3 Planner functions as a Mounjaro half-life calculator by modeling tirzepatide's ~5-day half-life in its drug concentration charts. The calculator shows how Mounjaro levels rise after injection, peak around 24-72 hours, and gradually decline based on the elimination half-life. This visualization helps you understand when you're at peak medication levels versus when levels are lowest before your next dose. Shotsy offers similar visualization but only with a premium subscription.
How do I calculate my retatrutide dose?
For retatrutide dosing, GLP3 Planner offers a free calculator specifically designed for this emerging triple-agonist medication. The standard retatrutide titration starts at 2mg weekly, increasing to 4mg, 8mg, and up to 12mg based on tolerance. GLP3 Planner's calculator models retatrutide's ~6-day half-life and supports both standard weekly dosing and microdosing protocols. See our complete retatrutide dosing guide for detailed titration schedules.
