Verdict
The clearest difference is in-app purchases: ChartLogs at none against Finance Prediction's 5. ChartLogs also leads on update cadence (every 9 days vs monthly). Finance Prediction's advantage is ads (none vs shown) and iOS requirement (8.2 vs 18.0). On price and device support there is nothing between them.
