Today

One calm list for the whole day.

Everything due at the same time sits in one row. Morning vitamins? One tap on Take all. Injections keep their own row, because each one deserves its own moment.

  • Grouped by morning, noon, evening and bedtime, at times you set
  • Take, Take all and Snooze; tap a taken row to undo
  • Reminders arrive on time as notifications from your iPhone itself
  • The next dose glows amber when it's due, and only then
The Today screen: Next 8:00 AM Morning card with Take all, and the day's doses grouped by time.

Vial math

Peptide math, made visual.

Enter the powder in the vial and the bacteriostatic water you add. Doselight works out the concentration, shows the exact units on your syringe, then animates the draw so you can match it line for line.

  • Your syringe: 0.3, 0.5 or 1 mL insulin (U‑100), 1 mL tuberculin or 3 mL
  • Readability at a glance: lands on a mark, between marks, or below the smallest mark
  • A water suggestion that puts your dose on a whole unit
  • The vial's remaining amount drops with every dose you log
Mix a vial, syringe step: 250 mcg is 5 units, and the 0.3 mL insulin syringe is the best fit.
The draw screen: Draw to 2.5 units on a 0.3 mL insulin syringe, with a Mark as taken button.

  • Mixed and use-by dates; the 28-day default is yours to change
  • Stock that counts down as you take it
  • Refill and last-dose reminders before you run out

Questions, answered

Is Doselight medical advice?

No. Doselight is an organiser and a calculator. It doesn't diagnose, prescribe or recommend doses. Follow your label and your prescriber, and double-check every calculation before you use it.

Where is my data stored?

Only on your iPhone, in a local database. There is no account and no server, and nothing is sent to us. Reminders are scheduled on the device, too. Privacy policy →

Which syringes does it support?

U‑100 insulin syringes of 0.3 mL, 0.5 mL and 1 mL, a 1 mL tuberculin syringe and a 3 mL syringe. Doselight shows your dose in the marks of the one you pick.

Can I track vitamins and protein powder, too?

Yes. Pills, capsules, softgels, gummies, powders (by scoop or gram) and liquids or drops all work, with stock counts and refill reminders.

Is there an Android version?

Not yet. Doselight is made for iPhone first. News will appear on this site.

When can I download it?

Doselight is in beta on TestFlight right now and is coming soon to the App Store.
