The OTO was able to set up a program to water my front using four different zones. It seems very efficient. ### 1/5 — Buggy app *2026-08-11, version 4.0.6* 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. ### 5/5 — Love OTTO *2026-08-11, version 4.0.6* It is a great tool and saves me so much time and worry. ### 5/5 — Best purchase! *2026-08-10, version 4.0.6* It has been so simple to use and we love it!! Couldn’t be happier. We have one for the backyard and one for the front yard ### 3/5 — New scheduling update is confusing *2026-08-08, version 4.0.6* I liked the app better when you could set watering frequency based on each output. The scheduling system is confusing and was implemented poorly ### 5/5 — My best buy this summer! *2026-08-08, version 4.0.6* Fast to install and very easy to use! Love it! ### 5/5 — Great product! *2026-08-06, version 4.0.6* So easy to use ### 5/5 — Great sprinkler *2026-08-06, version 4.0.6* All I had to do was set 4 points and the sprinkler did the rest. ### 5/5 — great app *2026-08-03, version 4.0.6* Love the OTO, fully automatic ## Frequently asked questions about OtO Lawn ### What does the OtO Lawn Companion App do?
