Hey Product Hunt! 👋
I built MacKeymapper because I kept losing focus every time I switched apps on my Mac.
Cmd+Tab always felt like a speed bump — scan, click, miss, repeat.
The idea hit me when I saw my old iPhone sitting unused on my desk. What if that screen
always showed exactly the apps I need, ready to tap instantly?
A few things I'm proud of:
- iOS 16+ support — most "retired" iPhones work perfectly as a dedicated Mac controller
- Zero server involvement — purely local network, so it works offline via iPhone hotspot too
- The free tier is genuinely useful (4 app shortcuts, not a fake limit to force upgrades)
🎁 Launch offer for Product Hunt:
The first 500 people get Premium free (unlimited apps + no ads + custom wallpaper).

Would love to hear what apps you'd put on your iPhone controller.
Happy to answer any questions!
