# Fing vs Dev Calc

The clearest difference is rating: Fing at 4.6 against Dev Calc's 2.0. Fing also leads on ratings volume (116K vs 2) and chart position (#106 vs unranked). Dev Calc's advantage is review sentiment (60% vs 35%) and iOS requirement (13.0 vs 16.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fing sells 7 in-app purchases, starting at $0.99 per 3 months and Dev Calc sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Fing holds the better App Store score, 4.6 against 2.0. That said, the two scores are not equally well evidenced: Fing has 116K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 35% of Fing's written reviews are positive against 60% of Dev Calc's, so the app with the better star average is not the one people write more warmly about.

Fing ships an update every 4 weeks, Dev Calc every 2 months. The most recent releases landed on September 25, 2026 and June 4, 2026 respectively.
