Track every dose. Trust your protocol.
DoseFlow is a private, on-device tracker for peptides, hormones and research compounds. Decay curves, vial math, site rotation, lab overlays — designed for people who care about precision.
Everything you need. Nothing you don't.
Built around the metrics that actually matter — half-life decay, adherence, vial economics, site rotation. No social feed. No ads. No cloud.
Decay curves, live
Pharmacokinetic modeling per compound. See exactly what's active in your system at any moment.
Reconstitution math
Vial size, BAC water, target dose — get exact draw volumes in IU. No mental math.
Smart site rotation
Track where your last injection went and get a suggested next site automatically.
Adherence at a glance
30-day grid view of every protocol. Know which compounds you're nailing.
Vial economics
Doses remaining, cost-per-dose, low-stock alerts. Know what to reorder, when.
On-device, always
Your data never leaves your phone. No accounts, no servers, no analytics.
Information density, without the noise.
Every screen designed around one question: what do you actually need to see right now?
Pharmacokinetics that read like a dashboard.
7-day history, 2-day projection, current load percentage and your dosing pattern overlaid. Switch to vial mode for reconstitution; switch to history for an audit log.
- Live half-life decay curve with future projection
- Adherence percentage per compound
- Tabbed view: Chart · History · Vial · Info
Plan a cycle. Watch it unfold.
See every dose laid out — past, present, and projected. Switch from calendar view to cycle view to see your active protocol as a single timeline.
- Color-coded compound dots on every day
- Cycle progress with start/end dates
- Projected calendar for upcoming months
Lab values. Body metrics. Correlated.
Toggle "Overlay dosing" to see exactly how your protocol changes lined up with your bloodwork. Track weight, body fat, testosterone, IGF-1 — and watch the curves move together.
- Body metrics with 30-day delta
- Lab markers with reference ranges
- Overlay your dosing schedule on any chart
Set up in under two minutes.
Add the compounds you're running. Log each dose with a tap. The rest is automatic.

"Finally an app that treats peptide tracking with the same rigor as a lab notebook. The decay curves are exactly what I wanted."
"The reconstitution calculator alone is worth the download. I haven't done a single math mistake on a vial since switching."
"Privacy-first means a lot when you're tracking sensitive data. Knowing nothing leaves my phone is the reason I stuck with it."
Stop guessing. Start tracking.
