Browser and Device Support
Date: 06 October 2022
This document applies to any development by clock that is deployed as website or as a native application on iOS and / or Android:
- For Websites, see the Browser section for which browsers are supported and on what operating systems / platforms
- For native apps on iOS and / or Android, see the Devices section for specific phone and software levels
We endeavour to ensure our sites work as expected in all modern browsers. The browser automatic upgrade process ensures that the majority of users will be using the latest versions. As a result of this, we test each in their current major release, and one version prior.
All browsers have varying levels of support for advanced features such as CSS animation and HTML5 APIs. Where possible, we will provide suitable fallbacks for browsers which don’t support these features.
We can extend support for specific browsers and devices on an ad-hoc per-client basis.
Older Versions of Supported Browsers
The browsers and devices listed are the versions we actively test in and maintain the codebase for. Older versions of Chrome, Firefox, Safari, and Edge should behave as expected but may contain minor functional or visual differences.
Third Party Browser Apps
Browsers such as Chrome or Opera Mini for iOS, Firefox for Android, or in-app browsers are not covered in the scope of our standard support list. Whilst these should work as expected, we can offer extended support to test projects using these browsers. Due to the large range of third-party browsers available, feature support may vary per-browser.
Operating System Variants and Versions
We assume that the supported versions of the outlined browsers behave identically on all versions of an operating system or device - i.e. we expect Chrome 41 to behave the same on Windows 11 and Windows 7, as we expect Safari 15.6.x to behave the same on any iPhone with iOS 16.x installed on it.
We only test on the latest versions of these operating systems however.
Desktop Browsers Support
Mobile Browsers Support
Latest Versions refers to the latest stable version and the version immediately before that.
We endeavour to ensure our apps work as expected on both Android and iOS. The general version release cycle for each platform varies - with iOS devices usually having automatic updates whereas vendors are responsible, but not obliged, to release new versions of Android.
This software variation introduces a substantial amount of support burden, but the Android device variation increases this.
As such, currently we build and test for a variety of flagship devices running the latest versions of operating systems available for those flagships. We are however limited by the support provided by our development tools.
We currently support iOS 16.0 or newer and all devices that are officially supported by Apple to run it.
Android 9.0 (API 28) or newer.
Underlying Application Support
While the officially supported versions are listed above, the underlying application, utilising no features of newer operating systems, can support iOS 12.4 and Android 5.0 (API 21) or newer.
