Now you can create and study cards on your Mac, and they'll seamlessly sync with Omen on iOS.

‡‡ Spaced Repetition

Omen will notify you at the optimal study times. Simply add your cards and obey Omen's commands, then clutch your skull in agony as your brain swells with knowledge.

‡‡ Ad Hoc Cards

If you stumble upon a useful piece of information, painlessly flashcardify it without undertaking the rituals of categorization. Decks are optional, so add cards ad hoc—from Omen itself or any app with a global hotkey—to a continuous stream of knowledge.

‡‡ Smart Card Creation

Vocabulary Definitions — Easily create cards from vocabulary words.

Shortcuts — Create cards with your voice via HomePod, Apple Watch, etc. Or create new cards from custom shortcuts in the Shortcuts app.

‡‡ Interleaved Practice

Studying cards from different decks in the same session makes for more effective memorization. All due cards are interleaved and studied on the gorgeously animated study screen.

‡‡ iCloud Backup/Sync

Synchronize and backup your cards seamlessly in the background between your different iOS and macOS devices.

‡‡ Pulchritude

Relish the gorgeous, tenebrous dark mode. Reel in ecstasy when studying on the deeply satisfying study screen. Pledge your eternal soul to the cool icons!

This is a very pretty and what looks to be a very functional app. I was wondering if there could be a dedicated settings menu with notification tweaks? I assume your algorithm is good but could be fun to have multiple settings of more crunch time oriented study weeks and more relaxed study weeks? Perhaps not? Also as an iPad user I would love if I could draw on the app or hand write. Just an idea, I don’t know how difficult it would be to implement but could be cool! Thank you for developing the app!

Also could you add folders? To organize my decks? After this coming semester I would like to catalog my old decks into a S’19 folder and that addition would greatly improve the look/feel and usability of the app!

all is great amazing interactions

but i wish i can return to the next line when i create a card
and i want to decide which deck to study cause sometimes i just want to store the cards and study them later. Not all cards need to learn.

Great and Simple!

Saw the promo on reddit, so I gave it a shot. Everything is simple, clean, and very well done. Like other comments I’ve seen, I’m definitely waiting on new themes!!

Will there be an upscale iPad version as well?
