About Rabbit Hole: Deep Dives
Everyone knows the feeling. One interesting question at midnight, and suddenly it's 2 a.m. and you've learned things you'll be telling people for weeks. Rabbit Hole is built for that feeling on purpose. It's a short-form deep-dive reader for the strange, the unsolved, and the quietly fascinating. Browse the Stack, one rabbit hole at a time, or scroll the List. Every card is an invitation to fall in. Tap a topic and you drop through layers, from the Surface, to Deeper, all the way down to The Abyss, the parts that keep you up at night. You choose how far you go. This is curiosity as a place you can actually visit, without an algorithm dragging you toward outrage. Come for one thing you didn't know. Leave with ten. WHAT'S INSIDE - Two ways to browse: Stack, one rabbit hole at a time with a swipe between sections, or List, a scrolling feed of cover cards - Unsolved, unsettling, and genuinely fascinating topics - Tap to fall in and read in layers: Surface, then Deeper, then The Abyss - You control the depth. Skim the surface or go all the way down - Clean, focused reading with nothing pulling you toward the next outrage DECKS - Research (free forever): deep dives into published research, each one cited to its sources - History: the moments, people, and turning points behind the world you know - Mysteries: the unsolved, the unexplained, and the questions with no easy answer Rabbit Hole is for the curious. The people who read the plaque, follow the footnote, and keep asking one more question. If that's you, this is your feed. Just don't blame us for the time. WHAT TO KNOW Research is free forever, with no limit. Mysteries and History give you five full rabbit holes plus a preview, then Rabbit Hole Plus unlocks everything. Rabbit Hole Plus is sold two ways. Lifetime is a one-time purchase: it does not renew and there is nothing to cancel. Monthly is an auto-renewing subscription with a free trial for eligible customers; payment is charged to your Apple Account at confirmation of purchase, or at the end of the free trial, and it renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings. Prices are shown in the app before you buy.

What’s new
Version 1.0.1 · Updated October 28, 2026
Two ways to browse. Stack is new and opens first: one rabbit hole fills the screen. Swipe up for the next one and sideways to change section. Each section picks up where you left off. Tap a card once to open the whole story in a sheet: the art, every layer, and for Research holes, the paper it comes from. Keep falling into the next hole, then swipe down to land back on the one you were reading. List is the scrolling feed you know, one tap away with the List | Stack switch at the top. More to read for free: History and Mysteries now open with five full rabbit holes instead of two. Research is still free forever. Holes you have read get a small Read mark and keep their place, so the order no longer shifts as you read. Card text now shows in full, and every tab keeps its title in a compact bar at the top. Settings has a new Reset Stack option that sends every section back to its first card.
