Verdict
The clearest difference is rating: Ref Tools at 3.9 against Embraco ToolBox's 3.0. Ref Tools also leads on update cadence (every 6 weeks vs every 4 months) and ratings volume (52 vs 6).

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Ref Tools holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Ref Tools has 52 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 58% of Ref Tools's written reviews are positive against 100% of Embraco ToolBox's, so the app with the better star average is not the one people write more warmly about.
Ref Tools ships an update every 6 weeks, Embraco ToolBox every 4 months. The most recent releases landed on September 19, 2026 and September 10, 2026 respectively.
