The precise tracker for real protocols.
Caliper does the reconstitution math, logs every dose, and keeps your stack, schedule, and trends in one calm, private place — so you can manage your protocol with confidence.
Caliper organizes your data — it doesn't recommend a dose, schedule, or outcome.

No more vial math in your head.
Compounded vials don't come dose-ready. You reconstitute the powder, then have to work out exactly how far to draw for your dose. Get it wrong and you're off by a lot.
Enter your vial strength, how much bacteriostatic water you added, and your dose. Caliper computes the exact draw — in units and milliliters — and shows you the mark to pull to.
- Works for any concentration and any compound
- Reads out in both insulin units and mL
- Save a vial once, reuse its concentration every time
Caliper does the arithmetic on the numbers you enter — it doesn't recommend a dose, schedule, or outcome.

Illustrative example. Caliper does the arithmetic on the numbers you enter — it doesn't recommend a dose. Always confirm against your vial and your provider.
Calculate, log, and watch the loop close.
The same simple rhythm every dose — so staying precise takes seconds, not spreadsheets.
- 01
Calculate your draw
Enter your vial strength, your water, and your dose. Caliper computes the exact draw in units and mL — no mental math at the counter.
- 02
Log the dose
One tap logs it. A live countdown shows when the next dose is due, and an “active in body” readout estimates how much is still working, based on each compound’s half-life.
- 03
Watch your trends
Weight, side effects, and dose changes line up on one timeline — so the patterns in your own data are easy to see, all on your device.
Everything your protocol needs, nothing it doesn't.
From the first reconstitution to your long-run trends — precise, private, and built for how people actually run stacks.
Flexible scheduling
Daily, several times a day, specific weekdays, every N days, or on/off cycles like 5-on / 2-off. Match how your protocol actually runs.

Multi-compound stacks
Track several compounds at once, each with its own schedule and concentration — your whole stack in one view.
Inventory & runway
Log vials (with reconstitution and use-by dates) and pens, then see how many days of supply you have left — so you reorder in time.
Progress trends
Weight over time with your goal and dose-change markers overlaid, so shifts in your own data are easy to spot.
Side effects & Insights
Log symptoms alongside your dose changes. An on-device Insights view surfaces patterns — and always points you to your provider.

Dose reminders
