Good for a specific task – Beyond Meditation Review

I have bounced among binaural beats apps and services for years now but I'm still quite the novice. That's why I'm revising my review and am bringing it down a notch. I could tell instantly that this app is a good one-- I love that it allows users to access multiple frequency levels and that many of the ambiance tracks are free. The in-store purchases are reasonable ($1.99 for a new frequency/wave level). It worked well for me during a couple meditation sessions and helped me get through writer's block and conquer insomnia. But the tracks are too short (30 minutes). I'm not great at meditating for a long time, but I can imagine it would be irritating to have the track end too soon. I'm also frustrated that it doesn't offer beta and gamma waves for the ADHD/depressive brain. So, in short, it's a good tool for a calming session, but it's not intended for focus and concentration.
