Momo Pocket is an app that lets you make convenient payments at hundreds of different stores using just your Android. And not only that, it also gives you access to exclusive discounts in some of those stores.
First of all, you need to register on Momo Pocket. When you do, you receive a user account number for Momo, which you can use to make payments through your device. This account number is completely independent from your usual bank account number.
The interface in Momo Pocket is pretty intuitive, and lets you both make payments and search for discounts in different shops, as long as they're near your location. For now, the app only works in Spain, and focuses especially on the south of the country.
Momo Pocket is an app with a lot of potential. With a few extra features and by expanding its services a little more, it could get quite a lot better.
