- Gaia (for offline maps)
- Backcountry navigator (another offline map app)
- Amazon appstore
- Quick Settings (just in case this reveals some settings)
- Kindle reader
- Runkeeper (there are others but this is what I'm using)
- Google Earth (IF your phone can run it)
- Firefox (for webgl etc, again, if your phone can run it)
- Barcode scanner (to read the 2d barcodes you see)
If you have some suggestions, post a comment.
