Verdict
The clearest difference is in-app purchases: Category Tally at none against Time Calculator ×'s 4. Category Tally also leads on ads (none vs shown) and update cadence (every 2 days vs every 6 months). Time Calculator ×'s advantage is device support (3 vs 1) and iOS requirement (15.6 vs 18.2). On price there is nothing between them.
