# Algorithms vs C++ Shell

The clearest difference is monetization model: Algorithms at free against C++ Shell's subscription. Algorithms also leads on update cadence (every 3 weeks vs every 3 months) and rating (4.5 vs 4.2). C++ Shell's advantage is ratings volume (224 vs 8) and iOS requirement (11.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Algorithms sells 3 one-off in-app purchases and C++ Shell sells 1 in-app purchase, starting at $4.49 per month. Whichever you choose, the download price is not the number that matters.

Algorithms holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: C++ Shell has 224 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 79% of Algorithms's written reviews are positive against 58% of C++ Shell's.

Algorithms ships an update every 3 weeks, C++ Shell every 3 months. The most recent releases landed on September 18, 2026 and September 21, 2026 respectively.
