No Option to Move Local Timezone Column Like the Others

The is a really good app that is slightly short of being great.

Currently, the Local timezone column is anchored at the top and cannot be moved. The option to move the Local Timezone column as we see fit instead of it anchored at the top of the Edit panel is crucial, we are able to move other timezones freely so local should not be excluded. And, a sort feature that organizes the columns by timezones, by timezones would be awesome and a different background highlight option to apply to each timezone would be a Chef’s kiss.

Enhancement Requests:
- Ability to move Local timezone like the others.
- Ability to sort Timezones by Timezones.
- Background highlight option for each timezone.

Simple to use

Just a great simple little app. Easy to use particularly when working with people across multiple time zones!

A Must Have for all Travelers

Such an easy way to stay on track with meetings in various time zones

A no frills efficient and well done App.

This is a great little app. I work with and in multiple timezones and this app has saved me on multiple occasions. Spend the $20 and compensate a good developer.

Great app - nasty adverts!

Love this app and have used for years! Unfortunately recently the advertising banner at the bottom on the free version has photos of penises, nude butts and lingerie!
I get the need to sell advertising to fund the free version but there should be some control over what customers see given the app is rated for 4+ age categories!
Nasty 😞
