Does it work outside US? Receiving a "Something went wrong..." popup when trying to register my phone number... (Singapore)

NUM 2.0 features a whole new cute User Interface with sound effects and music. On iPad it has a competitive 1vs1 mode. If you have an Apple Watch, install it to train your brain in your commute time. Thanks Piet for the hunt!

Really like the app icon and the widget design, especially when the iOS World Clock doesn't have a widget (yet).

Really like the game play and the design. Though the animations can be even better if there's highlighted state for the buttons. Sound effects are also nice, everything fits together.

Love the design. Especially the app icon, simple enough which doesn't make me feel 'stressed' when looking at something related to Work, has a feeling that it's embedded nicely next to the iOS Messages icon.

If you're stuck, here's a tip: divide, divide and divide until you get there. To be honest, I don't have a perfect solution either, I know there are a lot of insane math freaks out there that can solve level 46+ in seconds.
