A tracker app for Android
The calculator works out the number. The app is for remembering it.
This site already does the arithmetic. What it cannot do is remember what you did last Tuesday, which vial it came from, or when that vial was first punctured. That is the app: a log you keep on your own phone.
What it will do
Record a shot in two taps. Compound, amount, injection site, date and time. The things people currently keep in the Notes app, a spreadsheet, or nowhere.
Track vials, not just shots. When a vial was reconstituted, how much is left in it, and how long it has been open. The 28-day clock on bacteriostatic water and the shorter clock on the mixed solution are two separate clocks, and both are easy to lose track of.
Show you your own history. A calendar of what you actually did, and a rotation view for injection sites. Your data, exportable, deletable.
Work offline, without an account. Same as the calculator.
What it will not do
It will not tell you what to take, how much to take, how often, or whether any of it is safe or legal for you. It will not suggest a protocol, generate a schedule, or fill in a dose you did not enter yourself. There is no version of this app that gives dosing advice — not as a feature, not later, not by request.
That is a deliberate line rather than a temporary limitation. Software that recommends a dose for a person to inject is a different category of product with a different set of obligations, and we are not building that.
Get it
Dose Tool is on Google Play for Android. It is a paid subscription with a free trial on the yearly plan; the price is shown in the app before you subscribe. The calculator on this site stays free and needs nothing from you.
In the meantime, the reconstitution calculator and the cheat sheet are free and need no account.
