Remember That is a simple note taking app that was developed while I was co-owner of Colorize. Like CheckSite, this was a product that we created on the side in addition to creating media for customers.
Nowadays it seems like there are a million apps for taking notes. Back in 2011, most of these apps tended to be either overly basic or overly complex, especially on Android. This lead to us try and fill the niche of a note taking app that is simple, yet still has some reasonable features such as mutiple lists, sync between devices, and notifications.
Remember That started out as an Android app, but was eventually ported to an iOS app, a Mac app, and a web version. All of these can still be downloaded from their respective app stores, the links are also available from the product page at the Colorize website.
