# Sleek vs Outliner

The clearest difference is ads: Outliner at none against Sleek's shown. Outliner also leads on ratings volume (66 vs 6) and device support (4 vs 1). Sleek's advantage is rating (5.0 vs 4.7). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sleek sells 3 in-app purchases, starting at $1.99 per month and Outliner sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Sleek 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 6, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 11, 2026 and October 21, 2026 respectively.
