Verdict

The call

The clearest difference is in-app purchases: MindMatrix at none against TaskTetra's 1. MindMatrix also leads on ads (none vs shown) and update cadence (every 5 days vs every 15 months). TaskTetra's advantage is iOS requirement (16.0 vs 18.5). On price and device support there is nothing between them.
