PepMinder
Private peptide tracker: dose math, reminders, no account
PepMinder works out how many units to draw, shows it on a syringe diagram, reminds you on the schedule you set, and logs every dose with a body map. No account, no cloud: it all stays on your phone. Free on Android.
Hi Product Hunt 👋 I'm Tim, the solo developer of PepMinder.
I started it because I kept second-guessing my own reconstitution math and forgetting when I'd mixed a vial. Every tracker I tried wanted an account and a cloud sync for what should be private health data. So PepMinder has neither. There's no sign-up and no server. Everything lives on your phone.
What it does:
- Works out the units to draw and shows the fill line on a 30, 50 or 100-unit syringe
- Reminds you on the schedule you set, including dose steps that change by week, and lets you mark Taken, Snooze or Skip from the notification
- Logs every dose with a front and back body map showing days since each site was used
- Counts down your vial supply and warns before a mixed vial expires
- New in this version (Pro): an estimated level curve from your logged doses, using a half-life you enter
What it won't do, on purpose: suggest doses, protocols or half-life values. It's a calculator and a log. Those decisions belong with you and your provider.
For the developers here: it's Flutter, local-first SQLite through Drift, and exact alarms rebuilt from the database on every start. Before this release I ran a full regression that found and fixed about 150 bugs, mostly around reminders, time zones and daylight saving. The suite is now over 4,300 automated tests, and CI fails on any screen that overflows at large text sizes.
It's free for 2 peptides. It's Android-only for now; iOS is in progress.
I'd love blunt feedback: what would make you trust (or not trust) an app like this with your health data?
