Verdict
The clearest difference is update cadence: Time Lines at weekly against Calcbot 2's every 2 months. Time Lines also leads on review sentiment (80% vs 60%) and iOS requirement (13.0 vs 15.0). Calcbot 2's advantage is ratings volume (11K vs 8) and rating (4.7 vs 4.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calcbot 2 sells 1 one-off in-app purchase and Time Lines sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Calcbot 2 holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Calcbot 2 has 11K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 60% of Calcbot 2's written reviews are positive against 80% of Time Lines's, so the app with the better star average is not the one people write more warmly about.
Calcbot 2 ships an update every 2 months, Time Lines weekly. The most recent releases landed on October 13, 2026 and October 3, 2026 respectively.
