# Algorithms vs NL

The clearest difference is in-app purchases: NL at none against Algorithms's 3. NL also leads on iOS requirement (12.1 vs 15.6). Algorithms's advantage is chart position (#112 vs unranked). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Algorithms sells 3 one-off in-app purchases. NL asks for nothing beyond the download.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 18, 2026 and September 1, 2026 respectively.
