The important part is that it surfaces whichever comes first — running out or aging out — because a vial with doses left but past its window is just as much a "replace now" as an empty one.
In plain terms: it watches both the count and the calendar, and warns you on the earlier of the two.
Where vials come from
Save a calculator result to a vial, or add one manually. Either way, every subsequent draw and depletion is tracked automatically.
Inventory is a premium feature; the core dose-logging loop is free. It tracks what you have — it does not advise on obtaining anything. Open Zyra Labs to set up a vial.
Frequently asked
How does the app know when a vial will run out?
It derives the run-out date from the vial’s remaining doses and how often you log doses from it. It also tracks the reconstitution date so it can flag whichever comes first — running out or aging out.
What does a vial record hold?
The compound, its concentration, and total doses; the reconstitution date for the age window; and remaining doses, which decrement each time you log from it.
