# Unitly App vs Conversion Calculator

The clearest difference is in-app purchases: Unitly App at none against Conversion Calculator's 1. Unitly App also leads on rating (5.0 vs 4.8) and iOS requirement (13.0 vs 17.0). Conversion Calculator's advantage is ratings volume (157 vs 1) and update cadence (every 5 weeks vs every 5 months). On price, ads and device support there is nothing between them.

Both are free to download. Conversion Calculator sells 1 one-off in-app purchase. Unitly App asks for nothing beyond the download.

Unitly App holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Conversion Calculator has 157 ratings behind it against 1, so its average is the more settled of the two.

Unitly App ships an update every 5 months, Conversion Calculator every 5 weeks. The most recent releases landed on October 8, 2026 and October 9, 2026 respectively.
