A simple and effective Spaced repetition app. The app helps you to remember 100% of the important things you read - without any effort!

The app uses a scientifically supported spaced repetition algorithm to make sure you remember what you read. After adding a text (e.g., a quote or fact) you wish to remember, the app will then remind you about it according to a specific interval. It will keep reminding you until you have programmed the text into your long term memory.

According to science, you will only remember 20% of what you read after 30 days. This means that you will forget 80% of the personal development books you read. That is a lot of valuable information, time and money wasted!

The key to remembering is reviewing in intervals. The painful way to do this is to go back to your old books and review them all, one by one, month after month.
Seriously though, who has time for that?

Since we're personal development enthusiasts and techies ourselves, we asked: how can we develop something that maximizes memory with minimum effort? After researching the scientific literature for effective review strategies, we created Spaced - a simple app that helps you remember 100% of the important things you read - without any effort.

Spaced repetition is a scientifically proven learning technique that seeks to solve the problem of forgetting. It works by reminding you of important information at the moment you are about to forget it.

The theory of Spaced Repetition suggests an optimal repetition schedule for maximizing learning and memory. According to memory expert and author Piotr Woźniak, the perfect schedule is defined by two insights:

1. Intervals should be as long as possible to obtain the minimum frequency of repetitions, and to make the best use of the so-called spacing effect, which says that longer inter-repetition intervals, up to a certain limit, produce stronger memories
2. Intervals should be short enough to ensure that the knowledge is still remembered

By spacing out your learnings according to a specific repetition schedule, you will be able to learn faster and remember it longer. That is why spaced repetition has been referred to as “one of the most powerful methods for remembering what you learn” (Carrey – How we learn).

Perhaps one of the best and easiest-to-use apps on the market is the Spaced Repetition app for iOS. With the app, you can add any learning you want to remember, and the app then takes care of the rest. The app will automatically remind you according to a perfect Spaced repetition schedule. All you have to do is activating push notifications, and you’re all set. It has never been easier to hack your brain!

Transferring files/memos

Hi! I’m having trouble transferring my memos from my previous phone to my new one. As far as I remember, I was not asked to create an account on my first device so now I do not know how to do it. I wish you had an option to check the account or something similar.

PS: I’m using the same icloud id from before

Good Idea, Execution Lacking

The concept behind this app is solid, but the app’s execution of it is very minimal. The app doesn’t strike me as much more than the iOS Notes app with preset timed reminders for each entry — maybe not worth the $3 price tag that is revealed when you try to make more than a handful of entries.

I would find this app more useful with the incorporation of custom-timed reminders (and similarly the option of temporarily “silencing” certain entries), for more short-term and/or pressing memorization needs, and the option of uploading graphics for when the item to be memorized is visual.

Annoying notifications

Spaced is a simple app that makes it easy to set up reminders for spaced repetition.

Unfortunately, it also generates useless, content-free notifications daily whether or not it has a reminder for you. Unless I'm missing some setting, the only way to prevent this is to deny the app access to the notification center, which ruins the point of the app.

If it didn't spam my notifications, this would be a four or five stars app. As it is, I ended up deleting it--useless notifications are one of my pet peeves.
