Verdict

The call

The clearest difference is review sentiment: Mobile Master at 72% against Test Pro's 13%. Mobile Master also leads on rating (4.5 vs 3.6) and monetization model (free with in-app purchases vs subscription). Test Pro's advantage is ads (none vs shown) and iOS requirement (10.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.
