Verdict
The clearest difference is in-app purchases: TriGoTriFree at none against Right Triangle's 8. TriGoTriFree also leads on iOS requirement (7.0 vs 15.0). Right Triangle's advantage is update cadence (every 3 weeks vs every 5 months). On price, ads and device support there is nothing between them.
