CavernRemember What Matters.
Cavern helps you capture small things worth remembering, then review them effortlessly through a beautifully designed iPhone widget.
Type one thought. Cavern turns it into study cards, schedules reviews automatically, and brings them to your home screen when it's time to remember.
How Cavern Works
A simple flow designed around effortless memory practice.
Capture
Type a fact, idea, name, date, or phrase you want to remember.
Transform
Cavern uses AI to turn that input into clean study cards and multiple prompt styles.
Review
See cards in the home screen widget, reveal the answer, and mark whether you remembered it.
Retain
Spaced repetition schedules the next review so memory strengthens over time.
Study from your home screen.
Most memory apps ask you to sit down and start a session. Cavern brings review into the flow of daily life.
When a card is due, it appears right on your home screen, ready for a quick reveal. Tap to see the answer, then mark whether you remembered it with a simple "Got It" or "Forgot" action.
