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. No account is needed to log injections, set daily or weekly reminders, and view your history and Insights. Create a free account with Apple or Google to sync across your devices and to unlock advanced scheduling — cycles, titration (warm-up), and custom interval reminders. 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 exactly what's happening between each dose. Enjoy! For supported medications, the Insights tab turns your logbook into a live serum concentration dashboard. Injectly automatically pulls in the applicable medication you've been using, calculates current and projected levels based on your logged dose history and weight, and shows how close you are to peak along with how much of the dose remains active. Features: • Log each injection with dose, medication, date, time, route (SubQ/IM/IV), and injection site so you always have a searchable history — and can rotate sites. • Save and reuse custom protocols for peptides, prescriptions, or personal therapies in a couple of taps. • Reminders that match your cadence — daily, weekly, or specific weekdays — with multiple reminders per protocol and the dose amount shown right in the notification. • Cycles: run on/off schedules (weeks on, weeks off) with reminders that follow the cycle automatically. (free account) • Titration / warm-up: ramp a dose up or down over time, with a reminder for each step. (free account) • Custom interval reminders: schedule doses every X days and keep long-horizon reminders firing on time. (free account) • Review past and upcoming injections in the calendar or list view, with quick swipe actions to edit or delete. • Serum Concentration Insights: visualize past and future concentration curves, see percent-of-peak and remaining dose, and review pharmacokinetic details for select medications. • Blend protocols: create protocols for multi-peptide vials, see the per-ingredient dose breakdown for every injection, and get concentration insights for each individual constituent. • Medication Glossary: browse details for all supported medications in one dedicated view. • Your data, your control: export everything to CSV and delete your account and data anytime. • Available in English and German.
