# Right Angle vs Construction Calc Pro 7

The clearest difference is review sentiment: Right Angle at 73% against Construction Calc Pro 7's 25%. Right Angle also leads on ads (none vs shown) and update cadence (every 5 days vs every 2 months). Construction Calc Pro 7's advantage is rating (4.3 vs 3.9) and iOS requirement (15.6 vs 26.0). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Right Angle sells 9 in-app purchases, starting at $2.99 per month and Construction Calc Pro 7 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Construction Calc Pro 7 holds the better App Store score, 4.3 against 3.9. Both are backed by a comparable volume of ratings — 30 and 28 respectively. Written reviews complicate that: 73% of Right Angle's written reviews are positive against 25% of Construction Calc Pro 7's, so the app with the better star average is not the one people write more warmly about.
