+Older versions or other browsers might work, but are untested and unsupported. We'll try to to keep Nightscout compatible with older iPads (e.g. Safari on iOS 10.3.4), but note that those devices are not supported by Apple anymore and have known security issues. Debugging these old devices gets harder due to Apple not supporting debugging the old devices on Macs that have been updated. Some features may not work with devices/browsers on the older end of these requirements.
