Evidence

The homepage establishes subject browsing and free downloads across named mobile and connected devices, enough for a specific listener workflow at 60. It does not establish client parity or advanced controls.

Limits: AI review of saved source passages. No hands-on test, human approval or automatic-provider checker receipt.

Unconfirmed details may be unassessed, absent from the pages checked or temporarily unreadable. A missing price does not mean the service is free.

Sources and checks

Supporting pages for product usefulness, site facts, prices and separate website checks. Each record keeps its own date. Reading a page does not establish how well the product performs in use.
