Ratings and Reviews

Great service but the app UX could use some work.


Kato is an invaluable tool and asset for teams. This app works flawlessly 95% of the time with push notifications only failing once every few days. The user interface and experience can definitely be improved. Right now though it gets the job done and does it well. Kato is the future!

Best, most productive chat platform

Reid Elliott

My young company has rifled through several other chat platforms in our fist three years looking for something agile, smart, fun and developer friendly. Kato is everything we need and is an absolute joy to use in browser, on desktop, or on mobile.

Great communication tool

Homer Homie

We have used it extensively for our startup. We have 9 people in the team and it works marvelously. I tried out Slack because of the buzz but Kato is much better overall in terms of flexibilty and security
