SimpleLog Pro is a simple note taking app. It is designed for quick entry of notes with a minimal amount of screen touches. Everything is kept locally so there is no need for an internet connection. Just start the app, select a category, and start typing.
Log entries can be grouped into different categories. Each category can also have a unique template that is loaded when a new entry is selected. An example is the "Gas/Mileage" category that come pre-installed. Every time a new "Gas/Mileage" entry is created, "Odometer:" and "Gallons:" is automatically added to the note.
