# Outliner vs Backlog Studio

The clearest difference is review sentiment: Backlog Studio at 100% against Outliner's 77%. Backlog Studio also leads on rating (5.0 vs 4.7) and update cadence (every 2 weeks vs every 2 months). Outliner's advantage is ratings volume (66 vs 1) and device support (4 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Outliner sells 3 in-app purchases, starting at $3.99 per month and Backlog Studio sells 2 in-app purchases, starting at $29.99 per month. Whichever you choose, the download price is not the number that matters.

Backlog Studio holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Outliner has 66 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 77% of Outliner's written reviews are positive against 100% of Backlog Studio's.

Outliner ships an update every 2 months, Backlog Studio every 2 weeks. The most recent releases landed on October 21, 2026 and October 28, 2026 respectively.
