Your vials
A week after you mix a vial, it’s a clear bottle in the fridge with none of the numbers on it. This keeps them: each vial’s concentration, the units per draw, how many doses are left, and how many days until the discard date. Tap once per draw and it counts down, and send the discard date to your own calendar so you get reminded.
Want a nudge before a discard date?
Your vials stay in this browser. That does not change. Leave an address and you’ll hear when new measurement tools publish, and get discard-date reminders as soon as reminders launch.

How this works
Everything here is saved in this browser using its local storage. There’s no account and no server, and none of it is ever sent anywhere. That’s the feature: the list is yours and stays on your device. The trade-off is the honest one: it lives in this browser only, so clearing your history or switching devices starts you fresh.
The discard date defaults to 28 days, the in-use window on bacteriostatic-water labeling; adjust it per vial to match your own reference. Need to add one? Run a calculation and tap “Save this vial.”
