# One vs NebulaBuds

The clearest difference is rating: NebulaBuds at 4.4 against One's 2.3. NebulaBuds also leads on ratings volume (16K vs 188) and update cadence (every 2 weeks vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. One sells 10 one-off in-app purchases and NebulaBuds sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

NebulaBuds holds the better App Store score, 4.4 against 2.3. That said, the two scores are not equally well evidenced: NebulaBuds has 16K ratings behind it against 188, so its average is the more settled of the two. Written reviews point the same way: 14% of One's written reviews are positive against 25% of NebulaBuds's.

One ships an update monthly, NebulaBuds every 2 weeks. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
