Features
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
- Mark a dose Taken or Snooze it right from the notification
- A gentle follow-up 30 minutes later if a dose is still open, if you like
- The next dose glows amber when it's due, and only then
Vials
Your vial, the way you mixed it.
Record what's on the label and what you did: the powder, the water you added, when you mixed it and how long it keeps. Enter the amount to draw from your prescriber or product label, and the draw screen shows exactly that on your syringe, line for line. The numbers always come from you; Doselight keeps them and reminds you.
- Your syringe: 0.3, 0.5 or 1 mL insulin (U‑100), 1 mL tuberculin or 3 mL
- The draw you entered, shown on that syringe's own marks
- Already using a vial? Add it with the day you mixed it and about how much is left
- What's left in the vial goes down with every dose you log

An example of a record, not a recommendation. Doselight never suggests or derives a dose: the amount to draw is always what your prescriber or product label tells you.

Injection sites
Rotate sites without keeping notes.
Each time you log an injection, tap the spot on a simple body map. Doselight remembers where you went and points out the site you used longest ago, so rotating takes no thought.
- Front and back: abdomen, thighs, upper arms and glutes, left and right
- Suggested next: the site that has rested longest
- Recent sites on every vial, and on each dose in History
- Rather not record it this time? Choose Don't record
Sites
- Abdomen
- Thighs

Cabinet
Know what's left before it runs out.
Every vial shows what remains, when you mixed it and when to use it by. Pills, softgels, gummies, powders and liquids keep a running count, with a nudge to refill in time.
- Milligrams and doses left in each vial
- 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
Does Doselight calculate my dose?
No. Doselight is a log and a reminder. You enter your dose and the amount to draw exactly as your prescriber or the product label gives them; Doselight shows that amount on your syringe, reminds you on time and keeps the record. It never suggests, derives or checks a dose.
Is Doselight medical advice?
No. Doselight is an organiser, not a medical device. It doesn't diagnose, prescribe or recommend anything. Follow your prescriber and the product label.
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 →
Can I move my data to a new iPhone?
Yes. Settings → Your data → Back up saves a file wherever you choose, such as Files or iCloud Drive; Restore from backup on the new iPhone brings everything back. You can also export your history as a CSV spreadsheet.
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. The amount you enter is shown 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.
