# Optimal Coffee Extraction vs Single Origin

The clearest difference is price: Optimal Coffee Extraction at Free against Single Origin's $0.99. Optimal Coffee Extraction also leads on in-app purchases (none vs 1) and review sentiment (80% vs 67%). Single Origin's advantage is update cadence (every 9 days vs monthly) and rating (4.5 vs 4.3). On ads and device support there is nothing between them.

Optimal Coffee Extraction is free to download; Single Origin costs $0.99 up front. Single Origin sells 1 one-off in-app purchase. Optimal Coffee Extraction asks for nothing beyond the download.

Single Origin holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Single Origin has 99 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 80% of Optimal Coffee Extraction's written reviews are positive against 67% of Single Origin's, so the app with the better star average is not the one people write more warmly about.

Optimal Coffee Extraction ships an update monthly, Single Origin every 9 days. The most recent releases landed on September 29, 2026 and October 11, 2026 respectively.
