# Washboard vs sumFX

The clearest difference is rating: Washboard at 5.0 against sumFX's 4.4. Washboard also leads on price ($1.99 vs $9.99) and update cadence (every 3 months vs every 6 months). sumFX's advantage is ratings volume (12 vs 1) and review sentiment (55% vs 43%). On ads, in-app purchases, monetization model and device support there is nothing between them.

Washboard costs $1.99 and sumFX $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Washboard holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: sumFX has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of Washboard's written reviews are positive against 55% of sumFX's, so the app with the better star average is not the one people write more warmly about.

Washboard ships an update every 3 months, sumFX every 6 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
