One tap to start
Hit start at bedtime. Plunio does the rest.
“Are the nights getting better? I can’t remember”
“I’ll check plunio!”
“How bad was last night?”
“I lost count of how many times I got up!”
“Was last night better or worse?”
“They’re all blurring together”
“I think the nights are getting better”
“Are they though?”
“How many times did he wake up?”
“At least four… I think?”
An objective record of disrupted nights for parents.
Plunio listens in the background and gives you a clear summary - how many times the baby cried, for how long, and when.
It keeps track so you don't have to, you've got enough to do!
Track trends over weeks and months to see objectively if changes in routine are making a difference.

Plunio listens
An on-device machine learning model identifies crying and logs the timestamp, duration, and intensity of each event. No input needed. Up for a feed or settling? One tap logs calm awake time too.

Quick answers.
Does Plunio record audio?
No. Sound is analysed in real time and immediately discarded. No audio files are ever created or stored.
Does it need internet?
No. Everything runs on the device. It works in airplane mode.
Is it a baby monitor?
No. Plunio is a logging tool that gives you data after the fact. It is not an alert system or a replacement for direct supervision.
Can I log time my baby was awake but not crying?
Yes. Tap once when they wake for a feed, change or settling, and again when they're back asleep — or add it the next morning. Calm awake time shows alongside crying in summaries, history, and exports.
Can I share the data with a sleep consultant or GP?
Yes. One tap exports a two-page PDF sleep report — an overnight sleep map, night-by-night trends and plain-English observations — plus CSV for anyone who wants the raw numbers.
What if I change phones?
Back up your full history to a file you control and restore it on the new phone. Still no accounts and no cloud — the file never leaves your hands.
What devices does it work on?
Android phones running Android 8.0 or later.
Why did you make this?
I've got two kids and another one on the way, I remember how hard it is to know if nights are really getting better or worse!
Sleep-deprived brains forget.
Plunio doesn't.
