FREEWhat's in your fleet?
Add the models your team uses. We'll find the security-update deadlines.
Only model-level data. No serial numbers, employee names, or device access.
Can't find a model? Type it in. We flag what we can't verify-we never invent a date.
Evidence in.
Guesswork out.
A support policy is not a crystal ball.
We match exact models to published manufacturer commitments and US release months. Dates are policy-derived planning boundaries, not guarantees of a final patch. iPhone release history is evidence of past updates-not a fixed future deadline.
The coverage score is supported handsets past your horizon ÷ handsets with verified dates. Unverified handsets are excluded from both sides and shown separately. A high score is not proof that your entire fleet is covered.
AI only drafts the plain-language briefing. It never assigns support dates. Re-checks revisit the cited sources; a failed confirmation marks affected models Unverified instead of guessing. Preparation help only. Phone Lifespan is not a certification body, assessor, or insurer. Manufacturer support does not prove that a handset is patched. Verify OS patch levels in your MDM and regional SKU / carrier terms before purchase.
