• Syringe types U-100, U-50, U-40, U-30, and 1-5 mL Luer-Lock options
• Visual syringe draw guide, syringe-unit input mode, and water auto-calc
PROTOCOLS & SCHEDULES
• Save, duplicate, favorite, search, and drag-sort protocols and schedules
• Inline edits with instant recalculation
• Create schedules from saved protocols with start/end dates
• Multiple dose times per day with flexible cadences: daily, weekdays, every N days/weeks, or monthly
• Advanced titration ramps: ramp up/down by a set amount to a final dose
• On/off cycling windows for any medication
• Multiple schedules per protocol, color-coded and sortable
• Dose reminders with optional time-sensitive notifications
CALENDAR, LOGGING & ADHERENCE
• Calendar view plus pending doses list
• Log scheduled or as-needed doses with injection site, method, notes, and timestamps
• Custom injection sites with last-used hints
• Mark doses done, missed, or skipped
• Adherence metrics and streak tracking
• Log history with protocol filters
INVENTORY & SUPPLIES
• Track vials, pens, pills, and syringe supplies with remaining meter, manual adjustments, and percent remaining
• Runout estimates based on schedules or log history
• Low-stock alerts and container details (size, strength, lot/batch, source, storage, dates)
• Syringe supply inventory with auto-decrement and optional medication auto-refill tracking
INSIGHTS
• Biometrics dashboard for weight, body fat, sleep, resting heart rate, blood pressure, fasting glucose, HbA1c, testosterone, IGF-1, mood, energy, hunger, libido, and recovery
• Trend charts with 7/30/90/180/365-day views, baseline tracking, and weekly weight-change insights
• Manual entries, Apple Health import, and custom metrics for symptoms, side effects, labs, and more
• Dose overlay charts connecting logged doses, titration changes, and protocol timelines with biometric trends
• Medication levels dashboard with half-life curves, dose markers, steady-state estimates, and time-in-target insights
• Protocol filters and response summaries to compare medications with changes in weight, sleep, blood sugar, mood, hunger, and more
BACKUP, SYNC & SHARING
• Optional iCloud sync across devices
• Import backups for protocols, schedules, logs, injection sites, inventory, and insights data
• Export protocols, schedules, logs, and dose history to JSON, CSV, or PDF
• Automatic local backups with restore points
PERSONALIZE
• Dark, light, system, or custom themes with accent and tint options
• Locale-aware decimal input and haptic feedback
• "Party mode" celebrates consistency with glitter and accolades
• Use offline without an account; iCloud sync optional
PRIVACY
• We collect no user data.

This is a fabulous tool for dosing calculations, protocols, and schedules. The reminder feature is great and very adaptable. Dosing can be edited ‘on the fly’ and the feature showing doses per vial/amount left per vial are great features. It has been very beneficial and the app is very ‘feature rich’ in my opinion. A huge plus - it is updated and improved often!
Great Calculator / Tracker
BigBonanza7
Really does a great job! When you get a few of these going it can be hard to keep track and the app is a lifesaver when you forget what you planned to do. Even if you are not using the scheduler it is nice to be able to look at each Pep to see what the dose / volume is supposed to be.
Developer Response
Thank you for the kind words and review BigBonanza! If you have feature requests or run into any issues please send feedback through the app and I’m happy to address them.
Just the app I’ve been looking for
MAFlyBoy
I finally found a peptide tracking app that isn’t overly complicated and does exactly what I need it to do. Track my peptides, allow me to schedule them and remind me to take them. Makes reconstituting easy as well.
Developer Response
Thanks so much for the review and kind words! If you find you are missing any features or running into issues please send me feedback through settings and I’m happy to address them. That was definitely my goal to make the app intuitive and easy to use. Half life and biometric support coming soon.
Great App!

Great app! Very easy to use. Have tried a lot of the other peptide apps and this one has been the best by far. Simple way to organize and calculate peptides efficiently within the app. Layout is clear and intuitive. Support is top notch and very quick with their responses.
• Goals! Insights gets a major upgrade with biometric goals, milestone celebrations, local notifications, an All Goals view, a manual entries browser, and Today widget snapshots that spotlight your latest achievement.
• Archive Protocols! More flexible and easier to manage protocols, with archive and restore support that keeps history intact, explicit next-dose dates, hidden archived schedules, and more reliable recovery after sync or restore.
• Tracking in Insights is more powerful and more personal, with quick custom metric creation, built-in estrogen tracking, and clearer goal editing that makes progress easier to understand at a glance.
• Medication levels are easier to trust and tune with new Half-Lives screens in Protocols and Insights, per-medication half-life overrides, and broader built-in support including B12 and NAD+.
• Apple Health integration is broader and easier to follow, with more import coverage, clearer permission and sync status, and background refresh to help keep Insights current.
• Inventory is smarter about timing, with expired and expiring-soon warnings, expiration reminders, catch-up alerts for missed warnings, and safer forecasting for the dates that matter.
• Cycling schedules now give you a better heads-up, with optional alerts before a cycle restarts and before an off-cycle is about to end.
• Sync, restore, and import are more resilient across protocols, inventory, biometrics, goals, and half-life settings, helping prevent duplicate data, bad merges, and older records from overwriting newer changes.
• Dose logging, editing, and exports feel more polished, with Scheduled Log Dose defaulting to the current time again when needed, clearer next-dose timing, visible syringe calibration, preserved syringe calibration in history exports and imports, row-level peptide removal in protocol editing, and more helpful validation guidance throughout.
