Terrible app ### 5/5 — Great app and hardware *2024-09-14, version 2.4.1* We love our OpenSprinkler. We’ve used it since 2018 and it’s been reliable and easy to use. I also love the open API - I use it to prevent false alarms on my water leak sensor. ### 1/5 — App could’ve been so good *2024-03-26, version 2.4.0* I use this everyday in multiple greenhouses & I love how I can customize it down to the second with patterns but everything else seems so old school. You having to be on Wi-Fi to interact with the device is a huge hinder. The app also refreshes & updates super slow, if I want to stop a zone from running if I accidentally run the wrong one then I have to wait a good 20-30 seconds before it updates & I can stop it. ### 1/5 — Incompatible with voiceover *2022-10-10, version 2.2.5* I have been using this app for several years and voiceover compatibility has always been a bit of an issue. With the current version it is impossible to edit an existing program or create an new one. Disappointing. ### 5/5 — Great app and controller *2022-06-11, version 2.2.5* Reliable and super easy to use, makes setting up and running different sprinkler programs simple. ### 2/5 — Update deleted my OS sites (update: Twice now) *2021-04-12, version 2.2.4* This app has been fantastic for years. It managed two openSprinkler sites perfectly. then this last update deleted both sites and appeared to require a new login. I had to recreate the site settings. overall not a happy update experience. Review Update please let me know exactly many more of these fun updates i can expect that delete all my site info - 2nd in two weeks! yay! ### 3/5 — Loses Settings on Updates *2021-04-12, version 2.2.4* I set this up for my 75 year old Dad and it worked great last season. Recently, I keep having to re-add his two controllers to the app because it’s losing its configuration on app updates (presumably). He can’t do this (I’ve made an instruction document with screen shots since I’m 300 miles away to try to help); he is so frustrated. So yeah, kind of wishing I’d gone with some plug-n-play commercial system now with a better phone app. Also, the UI could be better. ### 3/5 — Won’t connect to controller *2021-04-10, version 2.2.4* Now it won’t connect to the controller. I’m able to log in using safari but it keeps saying to check IP/port and try again. ### 4/5 — I love the app I love the sprinkler controller. *2021-04-10, version 2.2.4* Even though I love this app and this device, twice now in one week we have had two updates (thank you I think), but twice now I need to reconnect to my devices connection info has been lost and I’m starting over again. Please if your going to update it again, can you figure out how to update it with out losing my connections and forcing me to start over. Thank you. ### 1/5 — Latest update *2021-04-04, version 2.2.2* What did you do?!?! Used to log in flawlessly no matter where I am. Now I get password error UNLESS I first VPN into my home network.... Why did you change things?!?! Please undo this change you made. I travel a lot and do not want to VPN just to use your app ## Frequently asked questions about OpenSprinkler ### What does the OpenSprinkler app do?
