Looking for 3 tablet apps.
1) Looking for a very simple photo sorting app, to help me sort large volumes of photos into neat categories. Basically, it would feature a normal image browser that lets me slide left and right to change pictures, but it would also have a simple overlay on the bottom or side with 4-6 user created categories and a delete button. Touching the category would move that photo to the folder associated with the category simply with no confirmation, and automatically move to the next image. If delete is pressed, the file is deleted (Or moved to a temporary "trash can" type folder that is emptied upon user request or at the end of the sorting session) and the next picture is displayed. The idea here is to be a very quick, single touch commands with no extra confirmation steps. To accommodate a larger amount of sort categories, they could be tree based. IE, a Sports category button could open 4 or 5 Specific sports related categories.
Also, if a photo is moved to a category folder with a duplicate name, both images should be displayed side by side with very basic file information (perhaps simply the image resolution), for simple verification of duplicates, an option of which file to keep and which to delete if they are duplicates (the resolution information helps you select the best quality one to keep), and the option to append a few random characters to the filename if they are not duplicates, and continue with the file move operation.
All of this needs to be simple and fast - other apps exist for this type of categorization, but it involves far too much slow navigation through menus and unnecessary confirmation steps. What I desire is for 95% of this process to be simply tapping the category, next image comes up, tap category, next image, don't like this one - tap delete, next image comes up.. etc. etc. The only time I get a popup is when a duplicate filename is found. I don't know how fast the files can actually be moved to the category folders, and hopefully that would be handled in the background without slowing down the sorting process. If it would significantly impact performance, perhaps instead of actually moving the files - it just makes a log of what needs to be moved, then every 500 or 1000 pictures you could press the "make it so" button, and it processes the log of needed file moves.
2) I want a typical virtual piano app that lets me assign an audio file for each key, for simple multi-sample playback. Extra points if it is able to stretch that audio sample across a few keys, playing back at the correct pitch.
3) I am looking for a music notation app that lets me write down simple melodic or harmonic ideas for composing. Something similar to the "simple note entry" method in Finale - select the note length, plus any accidentals, dots, or ties from a grid type menu and tap the note on the staff where I want to add it. I don't need a great deal of complexity, though some simple automation for barlines, spacing, and zooming in and out on a handful of staves would be needed. Extra bonus points if it can playback using midi.
I know there are iPad apps for music notation and custom sample based keyboards, but Android is seriously lacking in this department.
