So, here is a bare-bone list of apps that I personally used and found to be actually useful to guitarists:

4. Ear Tuner :

5. Reverse Chord Finder Free :
Tap in notes on the virtual fretboard and search for all chord names that match the shape you entered. Quite indispensable to me especially when figuring out names of uncommon chords from shapes played on the guitar.
File size : 7.7 Mb - This is quite a heavy app in terms of file size but there isn't anything else on the app store to match.

6. SoundForm Signal Generator :

Basic clarifications:
- All apps listed above have varying requirements and should be compatible with most current systems.
- All of them have been used by myself and found to live up to their claims
- All of them are free to download and use (some have built-in ads though).
- Efforts have been made to choose apps with the smallest file sizes for functionality on offer.
- All details and specifications are described as they were at the time of writing this post (20th August 2013).
- Apps that are actually browsers for tab/chord websites have been excluded.
