Verdict

The call

The clearest difference is in-app purchases: Calculator at none against Excel One's 1. Calculator also leads on ads (none vs shown). Excel One's advantage is update cadence (every 2 days vs every 6 months). On price, device support and iOS requirement there is nothing between them.
