A private second brain that lives entirely on your iPhone. Capture a thought, a name, a moment — then ask for it back in plain words. Nothing ever leaves the device.
Whatever you'd hate to forget — write it here. Watch it file itself away.
No folders, no tags, no homework. Hark organizes the moment you let go of it, and brings it back the way you'd think to ask.
Text, voice, a screenshot, a link. One tap and it's kept.
“That café Sara mentioned.” Hark understands time and context.
Capture in one, ask in the other. It keeps up either way.
Tap a question — watch it answer from memories that never left your phone.
Hark runs on Apple's on-device intelligence. No account, no cloud, no sync you didn't ask for. Your second brain stays where it belongs.
Today you ask, and Hark answers.
Soon, it won't wait to be asked.
ما قِيلَ مرّةً، يبقى.
Free to start. Nothing to sign up for. Just your iPhone and everything you'd rather not forget.
Requires iPhone 15 Pro or later · iOS 26+
