What's New in OtO Lawn

4.1.0

October 10, 2026

Keep an eye out for in-app tips and announcements highlighting new features and how to get the most out of them.

User reviews

Works, but only if you have a single device.

Update 9/2026:
This is the most confusing app ever. Nice update guys.

Previously:
I really like the app, it works great for setting the zones…surprisingly well. That said, once you get more than one zone it doesn’t coordinate timing across zones. Water pressure requires only one zone run at a time, and with four oto devices, each with multiple zones, it’s a nightmare to coordinate this timing without overlap. Please improve scheduling support.

Fantastic product

Love it sooo much

Simple to set up and runs very quietly

I have a odd shaped lawn with flower beds on three sides. The OTO was able to set up a program to water my front using four different zones. It seems very efficient.

Buggy app

The weather sensing functionality doesn’t work, sometimes it doesn’t water according to the schedule and you’re not notified. Now you can’t even water manually because their backend systems are faulty.

Love OTTO

It is a great tool and saves me so much time and worry.
