Verdict

The call

The clearest difference is review sentiment: OnefuncPlan at 67% against ToDo Calendar Pro's 20%. OnefuncPlan also leads on ads (none vs shown) and update cadence (every 4 days vs every 2 months). ToDo Calendar Pro's advantage is rating (4.2 vs 4.0) and device support (4 vs 2). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
