# Ad vs Unit converter

The clearest difference is rating: Unit converter at 4.9 against Ad's 3.9. Unit converter also leads on in-app purchases (none vs 1). Ad's advantage is ads (none vs shown) and update cadence (every 3 months vs every 24 months). On price and device support there is nothing between them.

Both are free to download. Ad sells 1 one-off in-app purchase. Unit converter asks for nothing beyond the download.

Unit converter holds the better App Store score, 4.9 against 3.9. Both are backed by a comparable volume of ratings — 56 and 14 respectively.

Ad ships an update every 3 months, Unit converter every 24 months. The most recent releases landed on November 4, 2026 and November 6, 2026 respectively.
