# VisualMind vs Petroleum Engineering+

The clearest difference is rating: Petroleum Engineering+ at 5.0 against VisualMind's 4.5. VisualMind's advantage is ratings volume (3.3K vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. VisualMind sells 9 in-app purchases, starting at $13.99 per 7 days and Petroleum Engineering+ sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Petroleum Engineering+ holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: VisualMind has 3.3K ratings behind it against 1, so its average is the more settled of the two.

VisualMind ships an update every 3 weeks, Petroleum Engineering+ monthly. Both last shipped on September 23, 2026.
