Verdict

PromoGrind wins on value at every price point. The free tier alone beats ProfitDuel's paid tier on calculator count. The paid layer is still the lower-cost option, but the honest comparison today is free calculators and tracking live now, with live scanning and AI rolled out only as backend services are activated. That still leaves PromoGrind as the stronger value play for a budget-conscious grinder.
