Stop second-guessing your mixing math. Type what went in and the total volume, and Reconstitute shows the concentration instantly. Convert units without thinking, save the calculations you need again, and keep a private log of your entries. Everything stays on your iPhone.
Free to download. First Pro month just $0.99. No ads, no account.
The math you redo every week, the numbers you scribble on sticky notes, the "wait, which one was it?" moments. Reconstitute catches all of them.
Type the solute quantity and the total volume. The mg/mL result appears while you type, plus mcg/mL, g/L and mg/L. No napkin math, no calculator app juggling.
mcg to mg, mL to µL, and back. One tap to flip direction. The mental gymnastics of moving decimal points is now the app's problem, not yours.
A few taps to record an entry: a label, an amount note, the date, the location. Weeks later you will actually know what you wrote down and when.
The logbook answers it at a glance: every location you record, ordered by least recently used, built entirely from your own entries. Your memory gets a backup.
Name a calculation, add notes, and reopen it next time instead of redoing it. Duplicate a record, tweak one number, done. Share any record as a clean image.
Sync with iCloud, add home-screen widgets, log from your Apple Watch, and export anything as CSV or PDF. Pro unlocks six accent themes with matching app icons. Light or dark, bigger text if you want it, and haptics that make every tap feel right.
You could keep using a notes app, a calculator, and your memory. Here is why people stop doing that.
Results update live as you type, computed on your iPhone at full precision. Open the app, get the number, get on with your day.
No account to create, no ads, no analytics, no tracking. Your entries are yours. Delete the app and everything is gone.
The calculator, the converter, and unlimited saved records cost nothing, forever. Pro exists only for the logbook power users.
Liquid-glass design, Dynamic Type, alternate icons, haptics. It looks and behaves like Apple built it.
Every calculation tool is free with no limits. Pro is for the logbook: when three entries stop being enough, unlock all of it.
Prefer yearly? $9.99/year, which works out to about $0.83/month.

It performs general solution-concentration math: a solute quantity (mcg, mg or g) divided by a total solution volume (µL, mL or L) gives the resulting concentration, shown in mg/mL and equivalent units. It also converts between metric mass units and between metric volume units.
No. Reconstitute does not determine, recommend, or verify medication dosages, and it must not be used to decide how much medication to take or administer. Always follow the instructions of a licensed healthcare professional and the official product labelling.
A private, personal record. You type your own entries: a label, an optional amount note, a date, and an optional location in your own words.

On your device, full stop. There are no accounts and no analytics. Subscriptions are processed by Apple; we never see your payment details. Deleting the app deletes your data.
