Live demo
One puff. Auto logged.
No tapping, no remembering. You puff, ExCap blinks, your phone gets the news.
Animation: a puff on the vape, the ExCap LED blinks, a Bluetooth signal travels to a phone, the ExHale app logs one more puff and Reddington cheers.
Tap the stage to puff againOrigin story
Same chip. New boss.
Every ExCap started out working for Big Vape. Then Reddington got hold of one.
Big Vape HQ
The Loyalty Cap
Big Vape built a little cap for every vape. It phoned home each puff, so InHale always knew when to offer "just the one" more.
Top shelf, corner office
One small heist
Reddington swiped one off the top shelf of Dreadington's corner office. He hates heights. He did it anyway.
Now
Ex-Big Vape. Ex-loyal.
He rewired it with a fork and flipped its loyalty. Now it's called ExCap, and it only reports to you.
How it works
Four steps. One click.
2
Pair it once
Open the ExHale app and hold ExCap close. It remembers your phone from then on.
3
Puff like normal
You draw through ExCap's own mouthpiece. A tiny pressure sensor feels every puff.
4
Watch your log
Each puff lands in your ExHale log with its time and length. No buttons. No typing.

Logs every puff
Counts each puff the moment it happens, with when and how long. Your log fills itself in.
Works offline
Phone left at home? ExCap keeps your puffs in its own memory and syncs the next time you're close.
USB-C charging
Charges over USB-C, right on the device. Design target: weeks per charge, about an hour to full.
Snug, tuned grip
A soft TPU grip insert holds it on. We're tuning the fit with test prints now, so tell us what you vape and we'll aim for it.
Pocket sized
A round puck about 25 mm across that sits over the mouthpiece. Goes where your vape goes.
Counts puffs. That's it.
Counts puffs. That's it.No microphone, no camera, no location. Just puff counts and times, sent to your ExHale app.
CAD model
Inspect it in 3D
The real round 3 prototype, loaded from the same CAD files we print. Spin it, pull it apart, then click it onto the vape.
Prototype - shape will changeLoading the 3D model...Real ExCap round 3 CAD: PETG body and cap, TPU grip insert, cover and skirt. Exploded shows the electronics inside: an nRF52840 Bluetooth module, a BMP581 pressure sensor, a 30 mAh battery, a buzz motor, the limit lock shutter, USB-C and the on-vape switch. The vape is a plain reference shape built from measurements, never printed.
New in round 3
New in round 3Round 3 power-ups
Big Vape built a loyalty cap. Reddington rewired it with a fork, then kept going.
Buzz at your limit
Buzz at your limitHit your daily limit and it buzzes. A tiny vibration motor, no screen to check.
Limit lock
Prototype featureA tiny magnetic shutter can close the airway at your limit, so the next puff is hard work. It's a nudge, not a safe: ExCap still comes off by hand.
USB-C on board
Charges over USB-C, right on the device. Same cable as everything else.
Rinse-clean mouthpiece
Rinse-clean mouthpieceThe mouthpiece comes off and rinses clean. The electronics stay sealed in a dry core.
Knows when it's on
A tiny switch knows when it's clipped on, so it only counts real puffs.
One shape, many vapes
One shape for round, rectangular and wedge-style disposables with a flat-oval mouthpiece. A soft grip holds it on: push on, pull off.

FAQ
FAQQuestions, answered
Will it fit my vape?
ExCap is one shape for round, rectangular and wedge-style disposables with a flat-oval mouthpiece. We're tuning the fit with test prints now, so tell us what you vape when you join.
Do I need the ExHale app?
Yes. Your puffs show up in the ExHale app. ExCap has no screen, just a tiny LED that blinks when it counts and a motor that buzzes at your limit.
What if my phone isn't nearby?
No problem. ExCap keeps your puffs in its own memory and syncs them next time your phone is in range.
How do I charge it?
With a USB-C cable, right on the device. Design target: a few weeks per charge and about an hour to full. We'll share real numbers once the prototype is tested.
Does it change how I vape?
You draw through ExCap's mouthpiece instead of the vape's, and your vape works like it always does. ExCap only listens for the puff, unless you switch on the limit lock.
Does it track where I am?
No. It counts puffs and when they happened. No location, no microphone, no camera.
How much will it cost?
How much will it cost?The price is still TBD. Waitlist players hear it first, before Batch 01 opens.
