The clearest difference is update cadence: OpenMHz at every 9 days against ALERT FM Toolkit's every 13 months. OpenMHz also leads on chart position (#79 vs unranked). ALERT FM Toolkit's advantage is iOS requirement (12.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.
