Results are shown in large, readable numbers, and the input fields are arranged so volume, time, and IV set settings are easy to recognize and tap. This helps you check the key values without unnecessary steps during busy clinical work.

On Apple Watch, you can quickly change infusion volume, administration time, or IV set, then follow the calculated rhythm with sound or haptics. Changes made on either device are synchronized automatically, including updates made on Apple Watch while your iPhone is not immediately at hand.

Sound and vibration rhythm checks help you confirm the calculated drip interval by feel. Multiple timers can support infusion and observation timing, and the drip quick chart lets you compare common reference values at a glance.

The free version includes the core drip calculation features. Pro unlocks custom drip factors, more records and timers, unlimited sound/vibration rhythm checks, and customization options. Pro is a one-time purchase, not a subscription.

Available in 33 languages, with support for iPhone, iPhone Duo, iPad, and Apple Watch.

This app is a reference tool for calculating drip count and drip volume. It does not replace medical decisions, treatment decisions, physician instructions, or facility protocols.
