DecsTheBest ,


I just recently started using this app due to COVID-19, so I can see what time I should be awake to play with them. I highly recommend this app if you want to figure out times and dates. This app has saved my life countless times. It is also quiet easy to use and is really simple. Sometimes the best apps are the super, simple ones. The one thing I have a problem with is, it took me a while to actually figure out what did what. So if it is possible developers, Mind adding a tutorial for people who are just discovering this app so they know how to use this app really quickly and see how amazing it can. Sincerely, A Fan.

Simple and effective

I have been using this app for over a year to help plan my work interactions with multiple countries on multiple continents. It is simple, efficient and effective. The way it allows you to pick a specific time and then lines up the others for visual view is very useful. And being able to save multiple views is handy depending on your use, E.g. personal or work. In addition, the multi-platform setup and integration with my google calendar allows seamless transition between devices. The only drawback is the login system can be a bit cumbersome if you need to setup on a new device.

Purchased version is worth every cent!

I use this App regularly as I converse with people around the world for work. This App gives me a clear insight into the best (& worst) time to call/text people. I first used the free version but for a small price I now have multiple time zones and can organise them how I wish. I also use the web-based version and screenshot my time versus my guest's time so we’re all on the same page.
The one improvement I’d ask for is an easier way to select time “chunks” on the web version.
Brilliant, simple, clear app. Love it!
