# EE ToolKit vs Unit Converter

The clearest difference is review sentiment: EE ToolKit at 90% against Unit Converter's 25%. EE ToolKit also leads on ads (none vs shown) and ratings volume (1.4K vs 7). Unit Converter's advantage is update cadence (weekly vs every 3 months) and rating (4.9 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. EE ToolKit sells 1 one-off in-app purchase and Unit Converter sells 10 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Unit Converter holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 90% of EE ToolKit's written reviews are positive against 25% of Unit Converter's, so the app with the better star average is not the one people write more warmly about.

EE ToolKit ships an update every 3 months, Unit Converter weekly. The most recent releases landed on September 23, 2026 and September 20, 2026 respectively.
