# Calculator + vs Timberlog

The clearest difference is ratings volume: Calculator + at 10K against Timberlog's 34. Calculator + also leads on update cadence (every 4 days vs every 2 weeks). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Timberlog sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Calculator + against 4.7 for Timberlog. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 34, so its average is the more settled of the two. Written reviews split almost evenly too, at 85% and 86% positive.

Calculator + ships an update every 4 days, Timberlog every 2 weeks. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
