# Toolbox PRO vs Flying Ruler

The clearest difference is rating: Toolbox PRO at 4.5 against Flying Ruler's 4.1. Toolbox PRO also leads on update cadence (fortnightly vs every 2 months) and ratings volume (3.5K vs 186). Flying Ruler's advantage is review sentiment (86% vs 62%) and price ($1.99 vs $3.99). On ads, in-app purchases, monetization model and device support there is nothing between them.

Toolbox PRO costs $3.99 and Flying Ruler $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Toolbox PRO holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Toolbox PRO has 3.5K ratings behind it against 186, so its average is the more settled of the two. Written reviews complicate that: 62% of Toolbox PRO's written reviews are positive against 86% of Flying Ruler's, so the app with the better star average is not the one people write more warmly about.

Toolbox PRO ships an update fortnightly, Flying Ruler every 2 months. The most recent releases landed on November 10, 2026 and November 6, 2026 respectively.
