# Converter vs Unit Ease

The clearest difference is in-app purchases: Converter at none against Unit Ease's 1. Converter also leads on ratings volume (897 vs 72). Unit Ease's advantage is update cadence (every 4 weeks vs every 2 months) and iOS requirement (13.0 vs 15.6). On price, rating, review sentiment and ads there is nothing between them.

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

That said, the two scores are not equally well evidenced: Converter has 897 ratings behind it against 72, so its average is the more settled of the two. Written reviews are what separate them: 94% of Converter's written reviews are positive against 95% of Unit Ease's.

Converter ships an update every 2 months, Unit Ease every 4 weeks. The most recent releases landed on October 18, 2026 and October 16, 2026 respectively.
