Verdict
The clearest difference is in-app purchases: Promptoll at none against DevBox's 1. Promptoll also leads on ads (none vs shown) and chart position (#195 vs unranked). DevBox's advantage is update cadence (every 3 days vs fortnightly). On price, device support and iOS requirement there is nothing between them.
