# GoodEar Pro vs Synesthesia

The clearest difference is rating: GoodEar Pro at 4.8 against Synesthesia's 2.3. GoodEar Pro also leads on review sentiment (77% vs 38%) and ratings volume (162 vs 16). Synesthesia's advantage is in-app purchases (none vs 4) and iOS requirement (8.0 vs 13.0). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. GoodEar Pro sells 4 in-app purchases, starting at $2.99 per month. Synesthesia asks for nothing beyond the download.

GoodEar Pro holds the better App Store score, 4.8 against 2.3.
