Verdict

The call

The clearest difference is review sentiment: T&M Mobile at 100% against Ugly's Electrical References's 47%. T&M Mobile also leads on price (Free vs $12.99) and iOS requirement (15.0 vs 17). Ugly's Electrical References's advantage is ratings volume (1.5K vs 6) and rating (4.4 vs 4.2). On update cadence, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Ugly's Electrical References holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Ugly's Electrical References has 1.5K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 100% of T&M Mobile's written reviews are positive against 47% of Ugly's Electrical References's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

T&M Mobile ships an update every 2 months, Ugly's Electrical References every 3 months. The most recent releases landed on October 24, 2026 and November 1, 2026 respectively.
