WHEN DOES IT MAKE SENSE TO SWITCH FROM SIMPLE DIAGNOSIS?
Four reasons people leave.
Decision triggers, not marketing. If two or more apply, your shortlist starts with the apps named below each card.
Pricing has outgrown your usage
If your usage of Simple Diagnosis has crossed a pricing-tier breakpoint, per-unit cost is usually where alternatives diverge most clearly.

Yoast SEO – Advanced SEO with real-time guidance and built-in AISupport response has slowed you down
Support quality is the hardest thing to read from a listing, and it is the most common reason a switch gets made. Read the most RECENT reviews on each alternative's profile rather than the lifetime average — recency is what tells you how the app is supported today, and trailing review velocity is the freshest signal AppRanks tracks.
