The GLP-1 tracker that does more than log your shot. Track every dose, see your estimated medication levels between shots, and watch your weight progress — all in seconds a day, no account required. ShotLock works with Zepbound®, Mounjaro®, Wegovy®, Ozempic®, Rybelsus®, Saxenda®, Victoza®, Trulicity®, Foundayo®, compounded semaglutide and tirzepatide, retatrutide, GLP-1 pills, and custom medications. TRACK EVERY DOSE IN SECONDS • One-tap logging for weekly shots and daily pills • Injection site rotation with smart "next site" suggestions • Dose history, pain levels, notes, and on-time streaks • Supply tracking so you always know how many doses you have left SEE WHAT'S IN YOUR BODY • Estimated medication level curves built on published pharmacokinetic research for each medication • Know your phase at a glance: Absorbing, At Peak, or Declining • Built-in Research Library with every study we rely on — no made-up numbers PROGRESS YOU CAN SEE • Weight tracking with goal progress, synced with Apple Health • Compare your results against published clinical trial data • Progress photos with onion-skin alignment for perfectly matched before-and-afters • Turn your journey into a shareable time-lapse video • Daily check-ins for side effects, cravings, energy, and mood — with insights that connect how you feel to where you are in your dose cycle WIDGETS AT A GLANCE • Shot Clock — a live countdown to your next dose, right on your home screen • In Your Body — your medication curve and current phase, no app open required • Streak Shield — your on-time streak and doses remaining, with a refill warning before you run out NEED A STRONGER REMINDER? (OPTIONAL) I built ShotLock because I take semaglutide and have ADHD — notifications were too easy to swipe away, and I kept missing shot day. So ShotLock includes something no other tracker has: an optional mode that locks your distracting apps at shot time until you log your dose. • Completely optional — most people use ShotLock as a classic tracker and reminder • Calls, messages, and essential system apps always stay available • Emergency unlock for when life happens • For those of us who need it: no more "I'll do it later" YOUR DATA, YOUR RULES • No account. No email. We create an anonymous identifier with nothing tied back to you • Your health data stays on your device • Switching apps? Import your dose history from other GLP-1 trackers in minutes • Export anytime: PDF summary for your doctor, CSV, or full backup Want ShotLock to track or sync something it doesn't yet? Request it on our roadmap right from the app — we ship fast. Available in English, Spanish, Portuguese, German, Japanese, Swedish, Danish, and Norwegian.
