# IQ Glassy vs Gridzen

The clearest difference is in-app purchases: Gridzen at none against IQ Glassy's 7. Gridzen also leads on review sentiment (100% vs 67%) and rating (5.0 vs 4.5). IQ Glassy's advantage is ratings volume (168 vs 1). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. IQ Glassy sells 7 one-off in-app purchases. Gridzen asks for nothing beyond the download.

Gridzen holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: IQ Glassy has 168 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 67% of IQ Glassy's written reviews are positive against 100% of Gridzen's.
