No lives. No second chances. If you're looking for an app that goes easy on you, this isn't it.

Verdict

The call

The clearest difference is ads: Protocol66 at none against LeanBudget's shown. Protocol66 also leads on iOS requirement (18.0 vs 26.0). LeanBudget's advantage is update cadence (every 6 days vs every 2 weeks). On price, in-app purchases and device support there is nothing between them.
