Ratings and reviews

Initially, for over a year, was awesome. Played perfectly. Last 2 updates though, changed something. It crashes within 1 to 2 songs. Deleted. Reinstalled. Worked a couple of times, then started crashing again. Deleted again. Not 100% sure if it's their update and/or Samsung's not playing, literally, well together. Too bad. It was a great non ad-intrusive app.

No, I do not use DSP enhancing. I have "Internal decoding" unchecked. --- @2020-10-11: Still the best, but unlike other music/radio players, it noticeably heats up all the devices on which I have used it (Pixel 3, Xperia Z5 Compact, Nokia X2DS). --- about @2020-04: I have been using its PC version for many years. Excellent player. The big pro: folder player + radio. This is a very rare combination. The only con: no sleep timer. Ah, v1.08 got a sleep timer. Now 1By1 is really #1 - functional, no frills, thin program - just a role model.

Best music app ever. I've been using it in my computer for donkey's years, never bothering with any of those fancy apps/programs; I just see them as a waste of time. Great to now see this on Google. I initially had to download an earlier version from the 1by1 website. As I say, I've used nothing else and never will. Top marks to the developers for this. 5 stars, easily.
