# AR鲁班尺 vs DeadLineTodo

The clearest difference is price: DeadLineTodo at Free against AR鲁班尺's $0.29. DeadLineTodo also leads on update cadence (every 3 days vs every 4 months). AR鲁班尺's advantage is rating (4.9 vs 4.5) and ratings volume (82 vs 2). On review sentiment, ads, in-app purchases and device support there is nothing between them.

DeadLineTodo is free to download; AR鲁班尺 costs $0.29 up front. AR鲁班尺 sells 7 in-app purchases, starting at $4.99 per month and DeadLineTodo sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

AR鲁班尺 holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: AR鲁班尺 has 82 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 94% of AR鲁班尺's written reviews are positive against 100% of DeadLineTodo's, so the app with the better star average is not the one people write more warmly about.

AR鲁班尺 ships an update every 4 months, DeadLineTodo every 3 days. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
