What's New in OnlyCat

6.1.0

August 28, 2026

A fresh look, pet profiles with stats, and OnlyCat on your wrist. ALMOST EVERY SCREEN REFRESHED We've revisited nearly every screen in the app with one goal: make it more usable, more approachable, and give it a fresh lick of paint. The event viewer got the biggest overhaul: videos open in a smooth slide-up card with a filmstrip along the bottom, so you can swipe straight between recent events — perfect for reviewing a night's comings and goings. Skip through in 5-second steps, save a still frame while paused, or rotate into fullscreen. PET PROFILES & STATS Every pet now has their own profile — add a photo, and it appears across the app. Each profile comes with a new stats view built from their real activity: • Comings and goings, peeks and blocked entries, with trends over time • Prey attempts — including how many days it's been since the last one • Their daily rhythm: busiest hours, favourite day of the week, average trips per day • A monthly transit chart to see long-term patterns emerge You can also add pets by entering their microchip number manually — handy for enrolling the whole household. ONLYCAT ON APPLE WATCH Our new watchOS app puts OnlyCat on your wrist: review the latest events and switch door policies without reaching for your phone. VIDEO IN NOTIFICATIONS Event notifications can now play video right there in the notification — see who's at the flap without even opening the app. AND PLENTY MORE • Door policy rules now support microchip read timeouts • New notification toggles for denied passages • Remote unlocks now show as extra detail on events in the activity feed • The detection feedback tool has been improved, to better guide reporting of incorrectly identified events • A badge on the Devices tab lets you know when your payment plan needs attention • Times and dates now follow your language and region settings • Improved crash reporting and dozens of smaller fixes and clean-ups

User reviews

App lets it down.

First things first, we love our OnlyCat cat flap. To date, it has stopped Nala bringing in 4 mice and 2 birds.
The reason I gave 4* instead of 5* is the app. Some of the wording of the alerts is confusing and you can’t do a great deal with the app.
It would be good to have some of the functionality seen on other well known brands:
- Clearer alert message. (“Cleared for Entry”, when an unknown cat approaches the cat flap does nothing for your blood pressure!)
- Filtering by cat name.
- Summary of each cat’s status (in or out) on a separate screen of the app
- indicating the cat has looked through the flap, rather than having gone through it
- Better use of the eInk display. Just having the word “Ready” displayed is a waste of real estate. Perhaps have a display of which cat is in and which is out (as shown in some of the early advertisements).
As I say, we love our OnlyCat. Just a few tweaks of the app and device itself would make it even more amazing.

Better than Sureflap

Roughly a week in using the OnlyCat cat flap and App. On the first night we prevented a mouse and a bird being brought in by our cat so the A.I. definitely works! The app allows various ways to control the entry and exit options and there are further improvements expected in the use of the e-ink screen which currently shows connection status but will hopefully soon show whether a cat is in or out. Highly Recommended

Only Cat smart cat flap

This has given us so much peace of mind, we’ve had it now for at least 8 months, it’s a brilliant bit of kit. We’ve had several detections but thankfully no live or dead mice, shrews or birds to chase / recover from around the house.

Works great

App works really well with the door. Set-up was super easy. I'm looking forward to having more options in the push notifications menu.

Gute Klappe, (noch) schlechte App

Das Konzept der Klappe ist super, aber die App (ios) ist noch sehr verbesserungsfähig
