Verdict
The clearest difference is rating: Prolon Focus at 4.5 against Wrench's 3.0. Prolon Focus also leads on ratings volume (85 vs 2) and review sentiment (67% vs 50%). Wrench's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement there is nothing between them.
