Product Gap Review

Use when stepping back to ask "what's actually missing here?" — not for bugs, for whole-product blind spots.

User journey

• First-time user landing → does the value prop register in 5 seconds?
• Sign-up friction — how many fields, how many emails, any captcha?
• First win — what's the smallest moment of "this works"? Is it surfaced?
• Return user — is there a reason to come back tomorrow?

Trust signals

• Real social proof (testimonials, counts, logos) — or vapor?
• About/Pricing/Contact present and honest?
• Legal: ToS, Privacy, refund policy?
• Security visible (HTTPS, no mixed content, no exposed keys)?

Conversion path

• Primary CTA visible above the fold on every page
• Pricing page exists and is unambiguous
• Checkout / signup works on mobile
• Empty states guide the user (not just blank screens)

Retention hooks

• Email capture before payment?
• Notification/digest opt-in?
• Onboarding sequence (even just 1 email)?
• Reason to log back in (new content, streak, social)?

Operational

• Support channel (email at minimum) listed
• Status page or way to communicate outages
• Refund / cancel flow doesn't require email war
• Logs/analytics let you debug a user complaint without screen-share

Differentiation

• One sentence answer to "why this vs. competitor X"
• One thing you do that they don't (or do better)
• One thing they do that you skipped on purpose — and you can defend it
