Verdict

The call

The clearest difference is ads: iFIT Personal Trainer at none against Specimen's shown. iFIT Personal Trainer also leads on ratings volume (1.4K vs 1) and chart position (#135 vs unranked). Specimen's advantage is rating (5.0 vs 4.7). On price, update cadence, in-app purchases and monetization model there is nothing between them.
