What’s New

Version 1.3

This time we added Swedish localization! So make sure to tell all your Swedish friends. We also improved the performance of the watch app, gave the monthly average temperature charts a bit more breathing room in places where the average high temperature reaches 100°, and improved dynamic type support.

Coming soon: Mercury for iPad and additional weather sources.

Love the line design for reading weather, super quick and easy way to get a feel for the upcoming conditions. For a new app there’s lots of potential - though definitely a few things that hopefully will be added soon: radar, humidity widget for the Lock Screen being two.

The only bug I’ve found so far is the current temp for the Apple Watch widget showing in Celsius instead of Fahrenheit.

Looks great; kinda buggy

I like the design and limited features. The weather items in the app are mostly what I use in my other weather app. Overall opinion: lots of attention to detail in the design; less in the functioning of the app. I'm using v1.1.4.

Main issues: It's slow to update weather in the app and in widgets/complications. App doesn't use background app refresh (not showing in my list). App is now forgetting that I have a subscription and switched all my widgets to demo mode; had to open the app settings to verify subscription; then widgets switched back. Watch app's name appears as a variable/key instead of app name in the complications lists (never seen that before). I had to reinstall the watch app for the complications to work. Also, my subscription shows as "Clear" instead of "Mercury"; who is Clear? I'd totally use this app if the polish applied to the design was applied to how it functions.

Imitation is the sincerest form of flattery

I wanted to give a small, young indie team a shot, but I ended up disappointed.

The app tries really hard to be a new Weatherline (RIP), but it does it poorly:
It’s more chaotic and less readable. It doesn’t offer any customization which results in scrolling and scrolling and scrolling - a poor use of screen space.
It’s got a very in your face design, which is not going to be everyone’s cup of tea (I’m not a fan), so the lack of themes or any adjustability hurts Mercury a lot.

Also, the price. It costs just slightly less than Carrot, but it doesn’t offer any additional data sources. If you’re relying only on WeatherKit, you should price your product accordingly. But really, you should just offer more providers.

It definitely takes guts to take on the already good stock weather app and phenomenal Carrot. I respect that.

Having said that, I don’t think Mercury will be successful. It’s just too far behind and I don’t think it will ever be able to catch up.
As a huge fan of Shark Tank and an *anonymous* AppStore reviewer I can’t help myself: you should take this app behind a barn, shoot it and then burn it.

I can see you’re talented devs, but I doubt this weather app is the best use of your talent.
