Verdict

The call

The clearest difference is price: UniPilot at Free against Probability's $1.99. UniPilot also leads on update cadence (every 5 weeks vs every 3 months). Probability's advantage is in-app purchases (none vs 1) and iOS requirement (14.0 vs 17.0). On ads and device support there is nothing between them.
