Písničky-Akordy is a free Android app developed by JOOMY that allows users to browse a database of songs and search for them just like they would on their mobile device. The only requirement is an internet connection. However, the main advantage is the ability for registered users to browse their favorite songs and songbooks without an internet connection. Although an internet connection is necessary to log in and download songs to your mobile device, once downloaded, you no longer need an internet connection. This means that you can create your own songbook at home on your computer, log in on your mobile device, wait for the songs to download, and then head out on a weekend hike with all your favorite songs and chords at your fingertips, regardless of internet availability.
