My Cafe Card Checker is a free iPhone app developed by Yuya Sakai. It falls under the category of Business & Productivity, specifically in the Finance subcategory. This app allows users to conveniently check the remaining balances of their prepaid cards for various cafes.

If you've ever thought, "I wish I could easily check my cafe card balances on an app" or "I want to see all my cafe cards in one place," then this app is perfect for you. With My Cafe Card Checker, you can quickly start using the app if you are already registered on the web services of the supported cafes (coffee shops).

The app currently supports checking the balances of prepaid cards for Dotour Coffee. Please note that starting from this version, support for Tully's Coffee has been excluded. Additionally, the app automatically deletes saved information for your security.

Key features of My Cafe Card Checker include the ability to check the balance of prepaid cards for each cafe, toggle the display of additional card information, automatically update information upon app launch (can be turned off), access the web services of each cafe through Safari, receive push notifications from the developer, display a widget, and access a guide on how to use the app.

Please note that using this app requires registration with one of the supported web services, such as "My Dotour - Dotour Value Card" provided by Dotour Coffee.
