Requirements: Android 3.0 and up
Overview: LectureNotes is an Android app for note-taking by handwriting on the screen, in particular with a stylus.
It is designed having a user at university (or at school) in mind, for instance a lecturer who is using it for preparing her/his lecture or even for actual teaching (by writing on the device and projecting the screen content for the audience) or a student who is using it for taking handwritten notes during a lecture. However, it has found many users outside academia, for instance businessmen who use it for sales presentation or artists who use it to create sketches and drawings.
Its major target devices are tablets with Android 3.0 or later (the development is done on a Lenovo ThinkPad Tablet with an N-trig stylus, a Samsung Galaxy Note 10.1 with an S-pen, and a Nexus 7 with an Adonit and a Wacom stylus). The basic functionality should work on all devices with Android 3.0 or later, but some which are hardware-dependent such as pressure sensitivity might not.
NOTE: There is a free trial version to test if the app is right for you. The free trial version is fully functional with the exception that the number of notebooks is constrained to two, with no more than eight pages per notebook.
If you encounter a problem with the app, please report it to me by email (devel [a] acadoid.com), I will do my very best to fix it quickly. The same holds true for suggestions and feature requests, please send them to me by email, as I cannot respond to a review in the market.
