# SolarWriter vs Buno Maker

The clearest difference is rating: Buno Maker at 5.0 against SolarWriter's 3.8. Buno Maker also leads on update cadence (every 9 days vs every 5 months). SolarWriter's advantage is ratings volume (16 vs 1) and iOS requirement (15.6 vs 17.0). 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 Buno Maker sells 5 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Buno Maker 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, Buno Maker every 9 days. The most recent releases landed on September 10, 2026 and September 6, 2026 respectively.
