We support any Android phone or iPhone with SIGNL4.
The minimum iOS version to run SIGNL4 is iOS 15. On Android devices the minimum OS version is 8 to run SIGNL4.
SIGNL4 mobile app version 3.14.0 requires iOS 15 or higher and as a result, we will stop supporting iOS 14 or lower on February 1st 2024
Please, note that certain devices (e.g. from Huawei) do not support push messaging via Google FCM and do thus not work with SIGNL4.
SIGNL4 can run on tablets but is not optimized for this form factor. Also, push messages are currently not supported on Apple iPad.
