Verdict
The clearest difference is review sentiment: FrackCalc at 100% against Intelex Mobile's 17%. FrackCalc also leads on rating (5.0 vs 2.1) and update cadence (weekly vs monthly). Intelex Mobile's advantage is price (Free vs $9.99) and ratings volume (113 vs 1). On ads, in-app purchases and device support there is nothing between them.
