### 5/5 — Time

*2026-05-04*

I see the Time number is really basic too

### 1/5 — you can’t even add a widget unless you pay

*2026-04-27, version 1.7.3*

literally can’t do anything unless you pay

### 1/5 — Get ready to pay

*2026-04-11, version 1.7.3*

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.

### 1/5 — Not worth an ongoing subscription

*2026-04-04*

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.

### 5/5 — improvement

*2026-04-01, version 1.7.3*

I am deaf and hard-of-hearing, may I have a vibrator to wake me up in the morning?

### 5/5 — Beautiful, simple, intuitive

*2026-03-16, version 1.7.3*

This is a beautifully designed, simple and intuitive world time app. I've always preferred a quick swipe action to change and see the effect on multiple world times. Usually this means swiping a world map, but having the swipe action simply on a clock face instead - genius idea. And implemented well.

### 5/5 — Amazing

*2026-01-25, version 1.7.3*

Well thought out app, great for managers

### 1/5 — Can’t add cities after purchase

*2026-01-19, version 1.7.3*

I purchased full price years ago when the price was low and now that the app has upgraded the app asks me to pay the full price again. I tried restoring the purchase but does not work. I am hoping they will honor a past full purchase.

### 3/5 — Wish it had better widgets

*2026-01-17*

This all does a great job showing multiple timelines- I LOVE the 24 hour clock showing all the zones I’ve selected. I just wish I could get that on my lock screen or as large widget. Maybe I’m missing something?

### 5/5 — The best Timezone helper

*2025-12-05, version 1.7.3*

I can't praise this app enough. Its user interface is second to none, and even the free version is brilliant and has everything you need to stay on top of your time zones. I decided to purchase the yearly subscription because I want to support the talented developers of this fantastic time zone converter. I hope you do the same because these guys deserve to be paid. Finally, a unique and truly helpful app that solves a big problem.
