Los Angeles – September 11, 2026 -- Peptide Tracker, a free iOS and Android app for logging peptide protocols, has rolled out three updates -- versions 2.15.0 through 2.17.0 -- adding split-dose tracking, a fully custom compound library, and new organization tools at no cost.
The app now supports doses drawn from two separate vials
When a single vial doesn't hold enough liquid for a full dose, users can split the draw across two vials, with the app guiding them through each vial's own syringe markings. The dose history log then reflects the split accurately. The setup process also now asks how a dose is measured before showing matching units, reducing mix-ups between drug amount and syringe marks.
Users can build custom compounds from scratch, including blends of up to five components
A new Custom Compounds section under Settings > Profile lets users rename, edit, add notes to, or delete compounds, or build entirely new ones. Compound search has also improved, matching names like "SS-31" or "AOD-9604" regardless of hyphenation.
Dose history now logs by the actual day a dose was taken, not the scheduled day
Doses logged after midnight count toward the prior evening, with a faint marker showing the original planned date. Users can also manually move a logged dose to a different day.
Discarded vials and ended protocols can now be restored
Version 2.16.0 lets users undo an accidental discard of a vial or supply from its detail screen without affecting doses already logged. Ended protocols can be shifted back to paused status and resumed later.
Protocols now get color-coding and a choice of week start day
Version 2.17.0 lets users assign each protocol one of eight colors, making protocols easier to distinguish across the Today, Stack, and dose history views. Active protocols can be reordered, with that order staying consistent throughout the app. Users can also set their week to start on Sunday or Monday, a feature the company says is useful outside the U.S.
"These updates come directly from how our users actually run their protocols," said Kevin Miller, Co-Founder and CEO of Peptide Tracker. "Doses don't always come from one vial, compounds aren't always in our library by default, and everyone organizes their stack differently."
All three updates are live now, free to use, with no subscription or paywall. Peptide Tracker launched in May 2026 and has since surpassed 50,000 downloads and logged over 748,000 doses, with an average App Store rating of 4.91.
