# Estimation Calculator vs iTrix

The clearest difference is rating: iTrix at 4.5 against Estimation Calculator's 3.3. iTrix also leads on ratings volume (6.7K vs 10). Estimation Calculator's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. iTrix sells 5 one-off in-app purchases. Estimation Calculator asks for nothing beyond the download.

iTrix holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: iTrix has 6.7K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 75% of Estimation Calculator's written reviews are positive against 42% of iTrix's, so the app with the better star average is not the one people write more warmly about.

Estimation Calculator ships an update every 2 months, iTrix every 6 weeks. The most recent releases landed on October 3, 2026 and October 26, 2026 respectively.
