# Programmer Calculator vs APP下载

The clearest difference is review sentiment: APP下载 at 100% against Programmer Calculator's 42%. APP下载 also leads on in-app purchases (none vs 3) and iOS requirement (11.0 vs 14.0). Programmer Calculator's advantage is rating (4.6 vs 2.0) and ratings volume (32 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Programmer Calculator sells 3 one-off in-app purchases. APP下载 asks for nothing beyond the download.

Programmer Calculator holds the better App Store score, 4.6 against 2.0. That said, the two scores are not equally well evidenced: Programmer Calculator has 32 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 42% of Programmer Calculator's written reviews are positive against 100% of APP下载's, so the app with the better star average is not the one people write more warmly about.

Programmer Calculator ships an update fortnightly, APP下载 every 9 days. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
