Nail Art Gallery (by Tattoos) – Last, but not least, this app was included for any Blackberry users that may still be around. Unfortunately, the app is only a photo gallery, but it offers hundreds of professional, high quality photos for inspiration. Most of the designs are done by nail technicians. The only downside is that the load time can take longer than expected.
This app is free and available through Blackberry App World.
