Why Dosei

The math and the memory, handled.

Protocols ask you to do arithmetic in your head, remember what was due, and keep track of what is left in each vial. Dosei takes that load off your shoulders without ever taking the decision out of your hands.

Without a system

Scattered and uncertain

Notes apps, spreadsheets, and mental math. It is hard to know what was logged, what is planned, and how much is left.

With Dosei

Organized and in your control

One calm place for calculation, logging, schedules, and inventory. You enter everything and make every call. Dosei keeps it accurate and in order.

Features

Designed to be precise, private, and calm.

A home screen that reports, not nags

See today's due doses, mark them taken in one tap, and review your own adherence over time. No streaks. No gamification.

  • Today's due doses with one-tap "Mark taken"
  • A 30-day adherence figure from your own logs
  • A 7-day activity chart and an 8-week adherence trend

Schedules and reminders, kept honest

Plan your doses and get notified when one is due. Logging is one tap. The plan and the record are kept separate, so what you intended never gets confused with what happened.

  • Plan doses and receive reminders
  • Log with one tap, with each dose marked taken or pending
  • Schedules (plan) and logs (reality) stay distinct

  • Concentration and doses remaining at a glance
  • Lot and expiry recorded per vial
  • Restock and expiry alerts from your own dates

  • All medications in one stack, filterable by category
  • Strength, draw volume, and units at a glance

FAQ

Questions, answered.

What can the Smart Calculator do?+

It detects what you are solving for — reconstitution, dose, or unit conversion — and shows the result large, along with the concentration in mg/ml and how many doses a vial holds. You can save a result as a preset to reuse later. It is free and unlimited, with no account.

Do I need an account to use Dosei?+

The Smart Calculator works with no account at all. When you want to log doses, plan schedules, and sync across devices, sign in with Apple or Google. Your sign-in stays the same everywhere you use Dosei.

Can I track any medication?+

Yes. You add each medication yourself — name, form, category, and color tag — so your records match exactly what you use. You stay in control of every entry, and Dosei handles the math and the memory around it.

Can I track more than one person?+

Yes. Switch between profiles for several people from one account, with a simple switcher. Pro includes 2 profiles and Family includes 5, with viewers per profile.

How does Dosei protect my privacy?+

Sign in with Apple or Google, keep your data in secure cloud sync, and lock the app behind Face ID or Touch ID. There are no ads, and nothing is sold. The Smart Calculator needs no account at all.

Which devices are supported?+

Dosei is a native app for iOS 16 and later, and Android 9 and later. The same account and data sync across both.

Is this medical advice?+

Dosei is a logging and calculation tool. It records what you enter and does the math; it does not provide medical advice and is not a substitute for a clinician. Every decision stays with you and the people you trust to advise you.
