In fifteen seconds
The whole gesture, at a glance.
1 · Enter volume and duration
2 · DROPP computes the rate
3 · Screen and Apple Watch beat the rhythm
4 · Match the drip, then start tracking
5 · Time remaining tracks itself
6 · The end reaches you — wherever you are
You know this moment
- The formula you know by heart — redone between two call bells.
- The clamp set by eye, recounted at the slightest doubt.
- Several end times to hold in your head, all shift long.
It isn't a question of skill. It's a load — and DROPP carries it.
Three gestures
Calculate
Volume and duration instantly become drops per minute, seconds per drop and mL/h. Drop factors 10, 15, 20 and 60 gtt/mL — this demo is set to 20. Nothing to memorize, nothing to redo.
Try it
Outside the plausible range — the app refuses to beat an absurd tempo.
Match
The scene beats the computed tempo — visible, felt on the wrist, audible if you turn it on (a discreet tick, no louder than a click, that respects silent mode). Adjust the clamp until unison: when the drip chamber's drop falls together with DROPP's, you're there.

Carry on
Time remaining tracks itself. A pre-alert warns you five minutes before the end, and reminders adapt to the duration — a midpoint mark for a one-hour infusion, regular checkpoints for one that runs through the night. The end no longer rests on memory alone.
Dropp Pro · Apple Watch
Everything, without reaching for your iPhone.
Start an infusion from the crown. Track it, pause it, find it by its label — Bay 3, Chair 5, Infusion A — without ever typing. Your wrist beats the tempo while you match the drip, and its alarms ring even if your iPhone stayed in your locker.
Dropp Pro · Double Tap
One gesture, without touching the screen.
Pinch your thumb and index finger twice: depending on the screen, DROPP starts the infusion, pauses it, resumes it, or acknowledges an alert. Hands full, hands gloved — the Apple Watch's native gesture answers at the wrist, no contact needed.
Apple Watch Series 9 or later.
Dropp Pro · Tap Mode
Watch a rhythm. Tap it. Read it.
Reproduce an observed rhythm by tapping the screen: DROPP shows its frequency per minute — no stopwatch, no mental math. For a drip rate, the reading also gives mL/h, enough to reset the clamp with confidence. On iPhone and on your wrist.
Try it
Dropp Pro · Simultaneous infusions
Every infusion: its label, its time, its alarm.
Place labels, never names — Bay 3, Chair 5, Hallway 2. The label is optional.

Straight answers
What stays free?
Unlimited calculations, the visual tempo, tracking for one infusion, and the end alarm — no ads, no account, no time limit.
Does DROPP work offline?
Yes, entirely. Everything is computed and stored on the device; no connection is ever needed.
Is the iPhone required with the Apple Watch?
Yes — the Watch app comes with the iPhone app and installs through it. After that, wrist alarms ring even if the iPhone is off or out of range.
Which drop factors are available?
10, 15, 20 and 60 drops per milliliter — the factor can be changed at any time in Settings.
What is Tap Mode for?
Reproducing an observed rhythm by tapping the screen to read its frequency per minute — and, for a drip rate, its mL/h. No stopwatch, no mental math.
Does DROPP replace a pump or a control device?
No. DROPP is an aid for calculation, rhythm and tracking. It measures nothing, decides nothing, and substitutes for no device or protocol.
Which versions are compatible?
iOS 17 or later, watchOS 10 or later.
