NJECTION App by Elias Sparagis Plan your medicine injection by tracking the spot of each dose and be notified for it. How it works? * Register using one of the supported social providers. Apple, Google login is currently supported. * Follow the required steps and fill the information needed to create a schedule for the injections. The wizard will run once and it is mandatory for using the app to complete it. * After completing the wizard the app creates for you a detailed plan for the injection containing information about the date and time, the body part, the zone (high, middle, low) and the depth of the needle in case of using an injection pistol. * By default notifications are enabled and you will be notified before each injection. Each notification displays an image of the exact spot of the injection. We developed this app with the intention to be helpful. Help us make it better. Your feedback is extremely valuable to us.

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.
