has released a funny tool focused on the eggs you can receive at PokéStops, and how much weight you might lose when you hatching them.

Start by entering your weight, decide which type of egg you want to hatch, and it will calculate your total calorie burn, how far you traveled, and your total weight loss potential.

The calculator also tells you how long it will take to hatch your egg so you can plan out your workouts, and lets you modify your speed so you can use it if you want to run instead of walk:

Use our calculator to quickly figure out how many calories you’ll burn while hatching particular eggs and also how much weight you could lose in the process. Choose the type of egg you found, enter the number and grab the results. You can also do reverse calculations — figure out how many eggs you should hatch to lose, say, 1 pound. Or check how many eggs you can hatch while walking at particular speed (consider running too!)
