Remember anything. Forever. Start by creating your own cards for what you want to remember. Ukulele chords, mathematics, or your friends’ birthdays. Question on the front and answer on the back.

Love it. ### 5/5 — Ask for update *2024-12-21, version 1.4.5* Please update the app to be available to sync with iCloud and other devices, I spent a lot of time on making flash cards and I’m worried to lose them ### 4/5 — bugs when editing cards *2023-11-30* I'm using an iphone and I cannot edit the cards' content I have created before. Also would be nice if I can adjust the font size and alignments. In all it's a good app. I especially like that I can change the color of the texts and it's very helpful to memorize the words. ### 5/5 — Finally *2023-09-24* To who ever made this app U made my life so much easier I’ve been looking for a flash card app with a leitner box type system for reviewing it many many thanks man this was exactly what I was looking for ### 5/5 — Amazing app *2022-11-22, version 1.4.4* Much better than anki, which is confusing ### 5/5 — Really useful *2022-09-01, version 1.4.3* I found this because of nicky case's article thing and its everything you could possibly need for spaced repetition, lots of helpful features and thank you for making it free and easy to use. ### 5/5 — Good stuff *2022-02-26, version 1.4.3* Very nice start. With a couple more functions this app would be amazing. 1, Optional text sizes would help optimize use of card space. 2, Creating card sets/categories would all users to organize their material. Pretty cool as is tho. ### 4/5 — Thanks + Request *2022-02-06, version 1.4.3* one of the most user-friendly apps available online for STR. So practical and easy to understand, but I wish I could paste lines that I copy from elsewhere! It’s a shame that this app lacks such a simple thing! ### 4/5 — Can Font size be bigger？ *2021-07-18, version 1.4.3* I love your app it’s very user friendly, however is it possible to adjust the font size bigger? That would be perfect！ Thanks for creating this app. ### 4/5 — This is a very good app. Pencil support please. *2021-07-14, version 1.4.3* This is a very sleek app and does just what it I supposed to do. Would be perfect if it supported Apple Pencil. Thank you for a very good app. ## Frequently asked questions about Spaced Repetition by Wärn ### How does Spaced Repetition by Wärn help me remember things?

Fixes an issue which made it difficult to paste text onto an empty card. 2. Fixes an issue which made it difficult to resize small text. ### 1.4.3 — 2021-03-27 In the previous version I tried to fix a crash on launch that a user was experiencing. While I did find and fix a crash, it was actually not the crash the user was having. So I went digging again. With the help of a crash report that the user shared with me I was able to find another problem with the code – and now it’s fixed! So if you were experiencing a crash on launch this version should hopefully fix it. If you still experience any issues with the app please feel free to contact me at carlolof@johanneswarn.com ### 1.4.2 — 2021-03-23 I heard from a user for whom the app had started to crash on launch. I believe I have found, and fixed, the issue that was causing the app to crash for them. Hopefully the app will be a bit faster for everyone else as well as a result. ### 1.4.1 — 2020-10-01 In this version I have fixed two iOS 14 issues that were introduced in the previous version (1.4.0). 1) When swiping cards they would animate into a very weird shape. This no longer happens. 2) When setting a custom time for reminders the time picker was a weird size. It has now been changed to it’s previous and intended size. Let me know if you find any other issues, and good luck with your learning.
