# Qualifier Plus IIIx/fx vs Mortgage Calculator +

The clearest difference is monetization model: Mortgage Calculator + at free with in-app purchases against Qualifier Plus IIIx/fx's subscription. Mortgage Calculator + also leads on update cadence (every 3 weeks vs every 10 months). Qualifier Plus IIIx/fx's advantage is rating (4.9 vs 4.6) and review sentiment (89% vs 68%).
