Injectly is the simple, yet powerful way to track your injectable medications. No ads, no subscription, and no tracking — just free help for staying on top of your regimen. Log every injection, set reminders that match your cadence, and review your history in a calendar or list. No account is needed for any of this. A free account with Apple or Google syncs your data across devices and unlocks advanced scheduling, such as on/off cycles and custom intervals. For supported medications, the Insights tab turns your logbook into a serum concentration view: an estimate of current and projected levels from the doses you've logged and your weight, how close you are to peak, and how much of the last dose is still active. Your health data is always yours: never sold, never used for advertising, and you can export or delete it anytime. Whether you're managing peptides, prescriptions, or personal health therapies, Injectly helps you log every injection, stay on schedule, and understand what's happening between each dose. Enjoy!
