Precision tracking,
total privacy.
Log every dose, manage vial inventory, and design multi-compound protocols — for peptides, TRT, supplements, and aesthetics. Stored locally on your iPhone, always.
Built to remove the guesswork
Draw with precision
An interactive syringe helper shows you exactly where the plunger should land — no more eyeballing a 0.3 mL draw.
See what's working
Weight, measurements, and labs plotted against every dose — so you can actually see whether a protocol is doing anything.
Never run out mid-cycle
Every vial's remaining volume, tracked automatically as you log doses, with low-stock alerts before you're caught short.
Designed for clarity, built for precision
Every screen is crafted to make managing your protocol effortless. See Vialr in action.
Get started in minutes
No complicated setup. Just download, add your peptides, and start tracking.
Add Your Compounds
Choose from a built-in library of peptides, hormones/TRT, supplements, nootropics, and aesthetics — or add custom compounds with concentration and reconstitution details.
Design Your Protocol
Set doses, frequency, on/off cycles, injection sites, and titration. Preview multi-compound cycles with a visual timeline and estimated blood-level curves.
Log, Track & Learn
Log each dose with one tap. Vialr tracks vial volume and site rotation, logs your bloodwork and body metrics, and surfaces the correlations that matter.
Built for privacy
Your data is yours. Vialr has no server to sell it from, breach, or hand over — because there's nowhere for it to live except your phone.
Stored on your device
Every dose, vial, and lab result lives in your phone's local database. Nothing is transmitted anywhere by default.
No account required
Open the app and start tracking. No sign-up, no email, no login screen standing between you and your data.
Backup stays yours
Turn on encrypted iCloud backup and it goes to your own private iCloud — there's no Vialr server for it to pass through.
Export whenever you want
A full JSON export of everything, any time. Your history isn't locked to the app.
