ShotLock vs Shotsy
Updated 2026-06-11
Shotsy is a polished, well-loved GLP-1 tracker with strong nutrition features. ShotLock matches the core tracking and adds the things Shotsy doesn't have: app-blocking shot protection, cycle-phase insights, and cited clinical-trial benchmarks.
Shotsy helped define the GLP-1 tracker category, and it remains an excellent app. This comparison sticks to what each app publicly offers today — including where Shotsy is genuinely ahead.

Frequently asked questions
Does Shotsy block apps like ShotLock does?
No. As of our last verification, Shotsy offers reminders and notifications. ShotLock is the only GLP-1 tracker we know of that can block all non-system third-party apps until your dose is logged, using Apple's Screen Time framework.
Do both apps estimate medication levels?
Yes — both Shotsy and ShotLock model estimated GLP-1 levels from your logged shots. ShotLock adds cycle phases on top: named stages of your week with typical side-effect context drawn from published trials.
Can I switch from Shotsy to ShotLock?
Yes. Set up your medication, schedule and current dose in ShotLock (about a minute), then log your most recent shot so your level curve and protection schedule start accurately. See our switching guide for the full checklist.
