I see the Time number is really basic too

you can’t even add a widget unless you pay

literally can’t do anything unless you pay
Gianna243Gianna243

Get ready to pay

Useless. Can't even test features like the advertised widget without signing your life away. Wish I hadn't installed it as it's now polluting my list of previously installed app. Don't be misled by the admittedly pretty icon - because that's all you get.

Not worth an ongoing subscription

Just no. This is pretty cool, but there are free apps with the same basic functionality. I’d even pay a one-time charge, but I’m sure as heck uninterested in paying month-by-month for what’s effectively a nominally useful gadget that I’m not likely to use daily. The useful things this app does are accomplished by the built-in clock. Give us a break with this saas nonsense.
