How it works
From weight to ml, no mental math
The calculation you'd do by hand on shift, on a single screen with a big result.
- 1
Weight
Enter the patient's weight in kg.
- 2
Dose
The dose in mcg, mg or g per kg, and whether it's the daily total or the amount per dose.
- 3
Interval
How often: 4, 6, 8, 12 or 24 h with one tap, or any interval you need.
- 4
Formulation
As the bottle says: “4 mg in 5 ml” or “8 %”.
Result
2.5 ml per dose
Volume per dose shown big, plus mg per dose and per day. A daily dose is split evenly across the interval.
Features
Built for the shift
Formulations in % or ml
- “4 mg in 5 ml” or “8 %”.
- Shows the math: 8 % = 8 g in 100 ml = 80 mg/ml.
- Accepts a decimal comma or point.
Per day or per dose
- Choose whether the dose is the daily total or the amount per dose.
- Dose in mcg, mg or g per kg.
- Small amounts are shown in mcg.
Saved formulations
- Save your medications with a name, dose, interval and concentration.
- Then pick one and enter only the weight.
- Search, edit or delete them anytime.
Save formulations
One payment, no subscription
Manual calculation is free and unlimited. To save your own formulations, there's a one-time in-app purchase.
Save formulations
- Create and edit named formulations.

- Restored with your App Store account if you reinstall.
USD 1.99 · one-time
The final price depends on your country and is set by the App Store. If the purchase is no longer active, your formulations stay: you can still view, use and delete them.
Privacy
No patient data
Dosis Kids has no server and no accounts. It doesn't store patient data: the weight you enter is used to calculate and isn't saved.
