# GoodEar Pro vs Open Studio Jazz

GoodEar Pro and Open Studio Jazz both sit at 4.8 stars, but that hides the real split: 100% of Open Studio Jazz's written reviews are positive against 77% of GoodEar Pro's. Open Studio Jazz also leads on update cadence (every 5 days vs every 4 weeks) and monetization model (free with in-app purchases vs paid). GoodEar Pro's advantage is ratings volume (166 vs 7). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. GoodEar Pro sells 4 in-app purchases, starting at $2.99 per month and Open Studio Jazz sells 4 in-app purchases, starting at $39.00 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for GoodEar Pro against 4.7 for Open Studio Jazz. That said, the two scores are not equally well evidenced: GoodEar Pro has 166 ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 77% of GoodEar Pro's written reviews are positive against 100% of Open Studio Jazz's.

GoodEar Pro ships an update every 4 weeks, Open Studio Jazz every 5 days. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
