Verdict
The clearest difference is review sentiment: MechTab at 89% against U's 0%. MechTab also leads on rating (4.1 vs 3.0) and ratings volume (16 vs 2). U's advantage is iOS requirement (11.0 vs 15.0). On price, update cadence, ads and in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
MechTab holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: MechTab has 16 ratings behind it against 2, so its average is the more settled of the two.
