Mapper opens Google Maps links, directions, addresses, and map thumbnails from Safari directly in Apple Maps, so you can stop copying and pasting addresses. Key features: - Redirect Google Maps links, addresses, direction buttons, and map thumbnails directly to Apple Maps. - Support every Google domain (google.com, .co.uk, .ca, etc.) on iOS and macOS. - Smart fallbacks: if Mapper can’t resolve a link, you’ll land on the Google Maps web app and then automatically redirect to Apple Maps. - Zero data collection: Mapper only scans for map links on Google search pages and never stores personal or location data. How it works: - Install Mapper and enable the extension in Settings → Safari → Extensions. - Browse to Google in Safari. - Tap any map link, directions button, or thumbnail. - Mapper grabs the address or search term and opens Apple Maps with a single tap. Mapper is built and maintained by a solo indie developer, ensuring it stays lightweight, reliable, and up-to-date. If you love Mapper, please consider leaving a rating or review.

Responder.ai is free to download; Mapper for Safari costs $1.99 up front. Responder.ai sells 5 in-app purchases, starting at $4.99 per 7 days. Mapper for Safari asks for nothing beyond the download.
Responder.ai holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Responder.ai has 3.9K ratings behind it against 612, so its average is the more settled of the two. Written reviews complicate that: 9% of Responder.ai's written reviews are positive against 67% of Mapper for Safari's, so the app with the better star average is not the one people write more warmly about.
Responder.ai ships an update every 2 months, Mapper for Safari every 3 days. Both last shipped on October 27, 2026.
