No network connectivity

After the current update, it does not find the OpenSprinkler server any more. Sorry guys, you should better test your software before releasing it. Not my favorite any more after that experience.

Terrible connectivity

Constantly crashes and fails to connect with my system. Terrible app

Great app and hardware

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.

App could’ve been so good

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.

Incompatible with voiceover

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.
