Free peptide tracker
Dosaly is a free app for keeping track of peptide vials, doses and reminders: it does the syringe math, knows what's left in every vial and works offline on your phone.

What it keeps track of
- Vials
- The amount, the water you added, the concentration and what's left after each dose.
- Doses
- Your schedule, with Taken, Snooze, Skip and a note for each dose.
- Reminders
- A notification when a dose is due, with quiet hours and as much or as little detail as you like.
- Supply
- The day each vial runs out, with a heads-up 14, 7 and 3 days before.
- How you feel
- A 30-second daily check-in, with trend charts.
- Bloodwork and notes
- Lab results per marker, and a private journal.
Why it's different
It installs from the browser and opens with no signal, logging doses offline and sending them when you're back. The math is shown, not hidden. It never recommends a dose or a compound, never sells anything and keeps no ad trackers.
