# Time Lines vs Overlap

The clearest difference is in-app purchases: Overlap at none against Time Lines's 1. Overlap also leads on ratings volume (849 vs 8) and rating (4.8 vs 4.5). Time Lines's advantage is update cadence (weekly vs every 3 months) and review sentiment (80% vs 67%). On price, ads and device support there is nothing between them.

Both are free to download. Time Lines sells 1 one-off in-app purchase. Overlap asks for nothing beyond the download.

Overlap holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Overlap has 849 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 80% of Time Lines's written reviews are positive against 67% of Overlap's, so the app with the better star average is not the one people write more warmly about.

Time Lines ships an update weekly, Overlap every 3 months. The most recent releases landed on October 3, 2026 and October 16, 2026 respectively.
