# SolarWriter vs Type Book

The clearest difference is rating: Type Book at 5.0 against SolarWriter's 3.8. Type Book also leads on update cadence (weekly vs every 5 months) and iOS requirement (9.0 vs 15.6). SolarWriter's advantage is ratings volume (16 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SolarWriter sells 1 one-off in-app purchase and Type Book sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Type Book holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: SolarWriter has 16 ratings behind it against 1, so its average is the more settled of the two.

SolarWriter ships an update every 5 months, Type Book weekly. The most recent releases landed on September 10, 2026 and June 24, 2026 respectively.
