Verdict
The clearest difference is in-app purchases: CallStart at none against High Frequency Highway's 10. CallStart also leads on iOS requirement (10.0 vs 17.0). High Frequency Highway's advantage is update cadence (every 9 days vs every 42 months) and chart position (#189 vs unranked). On price, ads and device support there is nothing between them.
