Injectly vs Cycle

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!

Cycle is the cleanest way to track peptide, TRT and hormone protocols — every injection, dose, lab result and health metric in one private, data-driven interface. Built for people who want clarity instead of clutter. Most protocols live in scattered notes, spreadsheets and memory. Cycle turns them into structured signal: log in seconds, then watch trend graphs, half-life decay curves and consistency scores make the patterns impossible to miss. WHAT YOU CAN TRACK - Compounds & doses — log every injection, dose and protocol with structured fields built for compounds, not generic notes - Half-life decay curves — visualize pharmacokinetic decay per compound so you can see what's actually in your system - Lab results & bloodwork — store and trend bloodwork over time; spot what's drifting before it becomes a problem - Health metrics — weight, blood pressure, mood and symptoms on one timeline - Daily checklist — a guided flow makes consistent logging effortless - Streaks & consistency — subtle feedback reinforces the habit without the noise INSIGHTS THAT ACTUALLY MEAN SOMETHING - Pharmacokinetic decay modeled per compound - Trend lines for weight, blood pressure, mood and symptoms - Consistency scores across any time window - Compare protocols side by side over time HOW IT WORKS 1. Set your protocol — define compounds, doses and frequency 2. Log with the checklist — injections, weight, BP, symptoms and labs in about 12 seconds a day 3. Read your insights — trends, decay curves and consistency scores translate raw entries into meaning BUILT FOR PRIVACY Your health data is personal, and Cycle is designed to keep it that way. By default your data is stored locally on your device. If you choose to sign in, your data is encrypted in transit and securely backed up so it can sync across your devices. We never sell your data and never share your health information with advertisers. FREE TO START Download and track for free.
