Good devices but poor app
The BP monitor is OK but the software works on fixed periods such as month or year. So if you want to see the current trend say over the past 15 days you are out of luck. You can only see the trend for calendar periods. This makes the app pretty useless for trends.
Air purifiers. They work ok. But the developers seem to be obsessed with making the devices beep for every action. So if you set the timer to switch off at night it wakes you up. Additionally the interface is fiddly. You can’t see the status of all devices in a category at one time. You have to open up each device to see what is going on. I think my 2 star rating is generous, this is because the devices are themselves not bad. The software is very poor on nearly all counts.
It’s a shame I can’t see other reviews.
