Vialy is a personal tracking and calculator tool for adults using prescribed peptides. It handles the math so you do not have to. Free. No ads. No subscriptions. No in-app purchases. RECONSTITUTE WITH CONFIDENCE Scrub the BAC water amount and watch the dose, the concentration, and the syringe units update live. No more squinting at a calculator app between hand washes. PLAN YOUR PROTOCOL Build phases with custom durations, scheduled days (daily, 5-on-2-off, weekly, or anything custom), dose in milligrams, multiple dose times per day, and a grace window for missed doses. Vialy keeps track of where you are in the protocol and what is next. LOG INJECTIONS Tap to log a dose from a body map. Vialy remembers each site you have used and warms up the map with halos so rotation becomes automatic. No spreadsheet required. TRACK YOUR VIALS Each vial shows the doses remaining, the estimated days until empty, and the cost. Plan-backed vials are sorted by soonest-empty first; as-needed vials get their own simpler view. Archive a vial when it is retired and the stats stay with it. PEPTIDE REFERENCE LIBRARY A built-in catalog of common peptides with mechanism notes, half-life, storage guidance, common side effects, and contraindications. This information is for context only and is not medical advice. DOSE REMINDERS Optional local notifications at your scheduled dose times, plus a heads-up when a vial is running low so you have time to reorder. EXPORT YOUR DATA JSON or CSV from Settings, anytime. Your data is yours. PRIVATE BY DESIGN - Sign in with Apple only - no passwords, no third-party logins - No tracking, no analytics, no advertising - No HealthKit access, no location, no camera, no contacts - Account deletion is one tap; your data is removed from our servers IMPORTANT Vialy is not a medical device and does not provide medical advice. It does not replace your clinician. All doses are entered by you for personal reference only. Always follow the guidance of a licensed clinician who has prescribed your protocol.

Verdict
The clearest difference is in-app purchases: Vialy at none against Strength Pilot's 3. Vialy also leads on update cadence (every 2 days vs every 5 days). Strength Pilot's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.
