# Algorithms vs LeetCard

The clearest difference is review sentiment: Algorithms at 91% against LeetCard's 54%. Algorithms also leads on ads (none vs shown) and rating (4.7 vs 4.5). LeetCard's advantage is update cadence (every 2 days vs every 6 weeks). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Algorithms sells 1 one-off in-app purchase and LeetCard sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Algorithms holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 101 and 80 respectively. Written reviews point the same way: 91% of Algorithms's written reviews are positive against 54% of LeetCard's.

Algorithms ships an update every 6 weeks, LeetCard every 2 days. The most recent releases landed on October 8, 2026 and October 9, 2026 respectively.
