Verdict
The clearest difference is rating: Mechanical Formula at 4.7 against Engineering HandBook's 4.0. Mechanical Formula also leads on ratings volume (34 vs 4). Engineering HandBook's advantage is in-app purchases (none vs 1) and update cadence (every 2 weeks vs every 4 months). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Mechanical Formula sells 1 one-off in-app purchase. Engineering HandBook asks for nothing beyond the download.
Mechanical Formula holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Mechanical Formula has 34 ratings behind it against 4, so its average is the more settled of the two.
Engineering HandBook ships an update every 2 weeks, Mechanical Formula every 4 months. The most recent releases landed on October 2, 2026 and October 6, 2026 respectively.
