## What is Omen?

‡‡ 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 either Omen, the home screen, or from another app —to a continuous stream of knowledge.


‡‡ Smart Card Creation

Vocabulary Definitions — If the front of your card is found in the dictionary, a cute little dictionary button will appear in the toolbar. Tapping this will reveal a list of definitions. Selecting a definition from the list will set the selected definition as the card’s back and add the card to the Vocabulary deck.

Table Imports — When browsing a website with a table, tapping the Add to Omen action extension lets you import the contents of the table as a deck, selecting one column for the front of each card and another for the back.

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. Simply tap “Study” and all due cards are interleaved and studied on the gorgeously animated, haptic feedback-enhanced study screen.


‡‡ iCloud Backup/Sync

Synchronize and backup your cards seamlessly in the background between your different iOS 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!

### 4/5 — Great! Until Montery 12.1

*2021-12-17, version 2.6*

I love(d) using this app for my flashcards, until the MacOS Monterey 12.1 update. Now, each time I open the app, it crashes.

### 3/5 — Fantastic app!

*2021-12-06, version 2.7*

What a beautiful and fantastic FlashCard app! Unfortunately it’s got a ton of bugs, and there is no way to contact the developer.

If the bugs are fixed, I will edit this review. I’d love to keep using it, but it’s slowly become unusable.

### 2/5 — Used to be much better on ios13 at some point.

*2021-05-19, version 2.7*

Can’t expect much from a free app but the author doesn’t want to fix the existing issues. Submitted quite a few of them for the previous versions of the app. They promised to fix them. The update bumped the minimum os version and I literally updated to 14 for this app. It still occasionally crashes(eg launch the app, open search..) The issue when the header becomes transparent… etc
I remember  messaging the dev with the question about the status of these issues, asking if they were resolved. But got no response.. Perhaps it’s better to switch to Anki. Animations are good though.

### 5/5 — all is great amazing interactions

*2019-06-28, version 1.1.0*

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.

### 5/5 — Questions

*2019-06-13, version 1.1.0*

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!

### 5/5 — Amazing!

*2019-05-19, version 1.1.0*

The UI/UX of this app is just perfect, can’t wait to see where it goes next. Keep it up, Kit!

### 5/5 — Great and Simple!

*2019-05-18, version 1.1.0*

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?
