# Arc+ vs WindowDraw

The clearest difference is review sentiment: WindowDraw at 100% against Arc+'s 50%. WindowDraw also leads on update cadence (every 2 weeks vs every 4 months) and rating (4.9 vs 4.6). Arc+'s advantage is monetization model (free vs freemium) and ratings volume (113 vs 7). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Arc+ sells 1 one-off in-app purchase and WindowDraw sells 3 in-app purchases, starting at $9.90 per month. Whichever you choose, the download price is not the number that matters.

WindowDraw holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Arc+ has 113 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 50% of Arc+'s written reviews are positive against 100% of WindowDraw's.

Arc+ ships an update every 4 months, WindowDraw every 2 weeks. The most recent releases landed on September 22, 2026 and September 19, 2026 respectively.
