# Construction Master Pro Calc vs Chippy Tools

The clearest difference is rating: Construction Master Pro Calc at 4.8 against Chippy Tools's 4.5. Construction Master Pro Calc also leads on ratings volume (40K vs 905) and chart position (#46 vs unranked). Chippy Tools's advantage is update cadence (every 8 days vs every 3 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Construction Master Pro Calc sells 12 in-app purchases, starting at $3.69 per month and Chippy Tools sells 9 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Construction Master Pro Calc holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Construction Master Pro Calc has 40K ratings behind it against 905, so its average is the more settled of the two.
