Cheap LED message notification options for iphone (and Android)
The iphone has no front notification LED but this also applies to most Androids when in pocket/bag. What are some cheap (under £10) devices that will notify of new messages using LED, ideally multi colour (RGB) options that can be set up? It can be an device (smartwatch, fitness tracker, etc.) but additional features are not really valued. I really just need something that will light up or blink repeatedly until acknowledged.
