Round-faced smartwatches like the Moto 360 and the soon-to-come LG G Watch R may look pretty, but aside from its shape, not much differentiates it from the more common square-faced ones. But of course developers would have to eventually create apps that would specifically look good and be functional as well on round smartwatches. Wear Tip Calculator may be one of the first to do so, and while its function is simple enough, it is pretty useful if you dine out often and have trouble computing tips.

Based on its name, what the app is used for is pretty self-explanatory. Yes, there are people who have a hard time computing what amount of tip should be left, even more so, when there are several of you splitting the bill. Wear Tip Calculator just has two-three simple steps for you. First, you input the total bill of your meal. Then, you add the tip, by choosing which percent of the bill you want to leave for your server. A bonus function is if you’re dining with friends or colleagues. Indicate how many of you are splitting the tip so it will compute how much each one of you have to contribute.

Aside from its functionality, the app truly takes advantage of the circular design for the Moto 360 and the G Watch R, as you swipe through the steps. The app will also work with the more common square Android Wear devices, but of course it would look a bit different and not as cute.

Wear Tip Calculator is free from the Google Play Store. But if you want that added function of dividing the tip, you would have to make a one-time in-app purchase of $1.
