# Algo Demo vs LeetCode

The clearest difference is in-app purchases: Algo Demo at none against LeetCode's 2. Algo Demo also leads on iOS requirement (13.0 vs 16.0). LeetCode's advantage is ads (none vs shown) and update cadence (fortnightly vs every 4 months). On price and device support there is nothing between them.

Both are free to download. LeetCode sells 2 in-app purchases, starting at $35.00 per month. Algo Demo asks for nothing beyond the download.

Algo Demo ships an update every 4 months, LeetCode fortnightly. The most recent releases landed on October 25, 2026 and October 28, 2026 respectively.
