Throttling detection
iGuard compares your evening speeds against your overnight speeds, day after day. When prime-time performance consistently drops below 80% of what your line does at 3am, that's a pattern — and iGuard flags it.
Breach quantification
Every test is measured against the plan speed you're paying for. iGuard tells you exactly what percentage of your tests fell short — "below plan speed on 47% of tests" is a fact, not a feeling.
Refund estimation
When the shortfall is persistent, iGuard estimates the refund your own measurements suggest you could pursue — a starting point for the conversation with your provider.
Private by design, not by promise
Your measurements are stored only in your browser. The free tier has no code path that uploads them anywhere — a claim you can verify, not just trust.
