Verdict

The call

The clearest difference is in-app purchases: 투다 at none against OneDayQuestion's 3. 투다 also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). OneDayQuestion's advantage is update cadence (every 4 days vs every 2 weeks). On price, review sentiment and device support there is nothing between them.
