Verdict
The clearest difference is in-app purchases: Deun at none against Expense Trail's 2. Deun also leads on iOS requirement (15.6 vs 18.0). Expense Trail's advantage is ads (none vs shown) and update cadence (every 9 days vs every 5 months). On price and device support there is nothing between them.
