# SolarWriter vs BYOK Studio

The clearest difference is rating: BYOK Studio at 5.0 against SolarWriter's 3.8. BYOK Studio also leads on review sentiment (100% vs 64%) and monetization model (free vs free with in-app purchases). SolarWriter's advantage is ratings volume (16 vs 2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. SolarWriter sells 1 one-off in-app purchase and BYOK Studio sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

BYOK Studio 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 2, so its average is the more settled of the two. Written reviews point the same way: 64% of SolarWriter's written reviews are positive against 100% of BYOK Studio's.

SolarWriter ships an update every 5 months, BYOK Studio every 5 weeks. The most recent releases landed on September 10, 2026 and September 15, 2026 respectively.
