Mind Stories provides regularly updated guided meditation tracks by Buddhist monks. By listening to their guides and meditating along, you can find better concentration and feel relaxed at the same time. Click the meditation tab and scroll to the "Meditation Guides" section, you will find albums that are suitable for your need.

Each album contains tracks that are typically sorted by their length. A limitation is that the app needs an Internet connection each time you play the track. Each play will also re-download the track, which may result in adding the amount of required Internet traffic. Clicking the small arrow-down icon before the minutes will download a track in advance. This will save the connecting time and the traffic the app may require.
