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