Search the phrase and you get a mixed bag: broker-built widgets and third-party trackers, wildly different in what they actually track.
- Pick the broker for its fees first, then enjoy the widget; do not invert that - The receiving broker's app has the freshest status, since it submits the ACATS request - iOS versus Android is cosmetic (widgets, notification styles, login type); the data underneath is identical - Demand stage timestamps, an estimated completion window, and a clear flag when action is needed - Most transfers take several business days; that is plumbing, not a problem
