Verdict
The clearest difference is rating: Mechanical Engineering Toolkit at 4.8 against Aisome's 3.5. Mechanical Engineering Toolkit also leads on ratings volume (64 vs 2). Aisome's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, review sentiment, update cadence 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 Engineering Toolkit sells 1 one-off in-app purchase. Aisome asks for nothing beyond the download.
Mechanical Engineering Toolkit holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: Mechanical Engineering Toolkit has 64 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 57% of Mechanical Engineering Toolkit's written reviews are positive against 50% of Aisome's.
Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 16, 2026 and October 2, 2026 respectively.
