GO Hatch Eggs is a free iPhone app developed by Marco Contino. Designed for gamers who want to hatch eggs in games faster and more efficiently, this app tracks your speed and sends you a notification when you are moving too fast to hatch eggs.

Whether you're running or biking, GO Hatch Eggs helps you maintain the optimal speed for egg hatching. The app recommends a speed threshold of 10.5 km/h, but this threshold can be customized by the user. When you exceed the recommended speed, the app sends you a notification with a custom sound, alerting you to slow down without the need to constantly check your device.

It's important to note that continued use of GPS running in the background can significantly decrease battery life. However, GO Hatch Eggs automatically powers down location services if you haven't moved for a while, helping to conserve battery power.

With GO Hatch Eggs, gamers can now hatch their eggs faster and more efficiently, allowing them to progress in their games with ease.
