PERSONALIZE
• Dark, light, system, or many custom themes
• Locale-aware decimal input and haptic feedback
• Celebration effects for consistency milestones
• Use offline without an account; iCloud sync optional
PRIVACY
• Use without creating an account
• Personal tracking data stays on device unless you enable iCloud sync

Important: PeptideCalc.io is an informational utility only. It does not diagnose conditions, prescribe treatment, recommend medications, recommend dosages, choose schedules, or determine whether any dose is appropriate. Always verify values independently and consult a qualified healthcare professional before making medical decisions.
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!
Incredible value and updated frequently

Easier to use than all the others and no subscriptions! Developer is very responsive to feature request and continually updates the app. I’m loving the new insights and half-life and biometric features. Thanks for making this!
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.
Game Changer
Walnut desk
I couldn’t keep my schedule straight and continuity is important, now I can keep 4 schedules straight, manage my vial inventory, titrate and reconstitute without thinking about it and keep all my dosing correct and accurate without thinking about. Thank for developing this app, it’s been a game changer for me.Sincerely, Roman
### What's New
Minor bug fixes
### Schedule & Sync
- Legacy hidden deleted schedules from the old delete path are cleaned up so offline deletes are less likely to return after iCloud sync.
- Cloud Sync status and feedback diagnostics now separate active and inactive protocol and schedule counts, making archived protocols and paused schedules easier to verify.
- Shifting a dose on an every-few-weeks schedule now keeps the future cadence anchored to the day you actually logged.
- iCloud protocol sync now avoids writing back incomplete local protocol data when the local protocol store did not load cleanly.
### Insights
- Goal setup now warns when the selected target direction would immediately mark the goal complete, and keeps that warning visible while editing.
### Backups & Diagnostics
- Automatic backups now avoid creating misleading restore points when protocol data failed to load.
### Stock
- Stock can now track insulin pen needles alongside syringe supplies.
