# Convert vs Unit Converter

The clearest difference is rating: Convert at 5.0 against Unit Converter's 3.7. Convert also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Unit Converter's advantage is update cadence (every 4 days vs every 5 weeks) and ratings volume (3 vs 1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Convert sells 2 one-off in-app purchases and Unit Converter sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Convert holds the better App Store score, 5.0 against 3.7. Both are backed by a comparable volume of ratings — 1 and 3 respectively. Written reviews point the same way: 60% of Convert's written reviews are positive against 50% of Unit Converter's.

Convert ships an update every 5 weeks, Unit Converter every 4 days. The most recent releases landed on September 10, 2026 and September 12, 2026 respectively.
