AppMachine supports both Android and iOS. We try to keep our apps compatible with as many older versions as possible, but eventually older OS versions will drop off.
AppMachine apps can not only be published as both native iOS and Android apps but also as a Progressive Web App (PWA). iOS apps are available for devices running iOS 13 and newer. Android apps can be run on devices running OS 8 or newer. PWAs can be launched in your device's browser and have the look and feel of a native app.
Please note that performance may vary on older Android and iOS devices. Older OS versions are the most often the cause for issues, but in some cases outdated hardware can cause problems as well.
Please contact our support department if you have any questions about the supported devices and OS versions: email@example.com.
