# Open Granular vs Isomorphic Keyboard

The clearest difference is review sentiment: Isomorphic Keyboard at 100% against Open Granular's 57%. Open Granular's advantage is rating (4.5 vs 3.5) and ratings volume (13 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Open Granular holds the better App Store score, 4.5 against 3.5. Both are backed by a comparable volume of ratings — 13 and 4 respectively.
