# Cloud Outliner vs Zero

The clearest difference is rating: Zero at 5.0 against Cloud Outliner's 4.5. Zero also leads on in-app purchases (none vs 1) and review sentiment (100% vs 80%). Cloud Outliner's advantage is ratings volume (751 vs 2) and update cadence (every 6 months vs every 22 months). On price, ads and device support there is nothing between them.

Both are free to download. Cloud Outliner sells 1 one-off in-app purchase. Zero asks for nothing beyond the download.
