Traditional screens are fantastic everywhere but outside, especially on a sunny day. E-ink screens work well, but e-readers like the Kindle are difficult to type on and don't support external keyboards. SolarWriter gives you the best of both worlds. SolarWriter runs on your iOS device and acts as a hub between your keyboard and your e-reader. You type on the keyboard, and the text appears on both on the iOS device and on the e-reader's screen (via its web browser). Take advantage of your Kindle's (or other e-reader's) e-ink screen to put your thoughts on paper even outside, with no need to transcribe later. Write at parks, on beaches, in backyards... anywhere you wanted to but couldn't. Save files on your device, or share through email, SMS, and more. Detailed instructions for setup are included inside the app.

Verdict
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.
