Early Review

Just got this app and I’m exploring right now. So far, so good. I got this because i want to learn Celsius and convert it to Fahrenheit. So far it is doing the job rather well and has some good extras. Very easy to follow on iPad but a little more work on iPhone. I just need to make sure I won’t be charged separately for my iPhone, iPad and MacBook Air.
Ok, I have had it a few days now and have learned to move through it. I’m very pleased.
Good job! Thank you

Best multi unit weather app

Well done adding radar maps.

Excellent app for comparing Fahrenheit and Centigrade

I love this app. It has helped me transition from F to C!

Great WX App

I got this app solely because it also showed Celsius. I have grown to really like it. The way it displays the info is concise and helps me quickly check out the day and coming week. Great app!

So handy

This has totally replaced the regular weather app for me. Lovely interface on the phone and super helpful for someone like me who is trying to convert from F to C.
