Peptide Log: Injection Diary

The Apple-grade injection companion. Log every shot, plan your own protocols, track lab markers, sync to Apple Watch and export a PDF for your doctor. 100% private.

Peptide Log is the iOS-native companion for keeping a personal injection routine organized. Built for iPhone, Apple Watch, and the Lock Screen, it brings your injection log, protocol planner, lab tracker, and a simple dilution helper into one premium experience with full Light and Dark mode.

— INJECTION LOG — Every shot, in one tidy timeline. Record what you took, the amount, and the site (abdomen, thigh, glute, deltoid — left and right). Quick-log re-runs your last entry in a single tap. The built-in site rotation suggests the next site automatically, so you never overload one spot.

— YOUR OWN PROTOCOLS — Plan your routine from scratch. You set the name, the amount, the frequency, and the duration — there are no presets and nothing is suggested for you. Every value is yours. The dashboard shows your next entry across all active protocols on one screen.

— DILUTION HELPER — A simple mixing-math aid. You enter the powder amount, the solvent volume, and the amount you want, and it returns the draw volume plus the equivalent marks on your insulin syringe (U-100, U-50, or U-40). It is pure arithmetic on the values you type — it never recommends a substance or an amount.

— LABS TRACKER — Log your own lab results — Total T, Free T, Estradiol, SHBG, Hematocrit, PSA, lipids, TSH, and more. Native Swift Charts plot every marker over time with a reference-range overlay so you can spot trends at a glance.

— TRENDS WITH HEALTH DATA — Optionally overlay weight, sleep, resting heart rate, and HRV from Apple Health on top of your timeline to see how your routine lines up with the metrics you care about.

— WIDGETS + APPLE WATCH — Home Screen and Lock Screen widgets show your next entry in real time. The Apple Watch app lets you quick-log from your wrist, with a complication that tracks weekly progress.

— PDF EXPORT — Generate a clean, professional PDF summary of your injection log and labs to share with your physician.

— PRIVACY-FIRST — Everything stays on your device. Optional iCloud private sync (CloudKit) keeps your iPhone, iPad, and Apple Watch in sync — never our servers. Zero analytics. Zero trackers. Zero accounts.

— LIGHT & DARK — Full Light and Dark mode, with System auto-switch.

— IMPORTANT — Peptide Log is a personal tracking and educational tool. It does not provide medical advice, does not recommend any substance or amount, and is not a substitute for professional care. Always consult your healthcare provider before starting, modifying, or stopping anything. The dilution helper performs only basic arithmetic on values you enter — always verify any measurement yourself.
