Verdict

The call

The clearest difference is rating: Construction Master Pro Calc at 4.8 against Time and Expense Center's 4.2. Construction Master Pro Calc also leads on ratings volume (40K vs 9) and chart position (#43 vs unranked). Time and Expense Center's advantage is review sentiment (83% vs 60%). On price, update cadence, 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 Time and Expense Center sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Construction Master Pro Calc holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Construction Master Pro Calc has 40K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 60% of Construction Master Pro Calc's written reviews are positive against 83% of Time and Expense Center's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Construction Master Pro Calc ships an update every 3 weeks, Time and Expense Center every 5 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
