📝 About this app
The VokabelBox is a vocabulary trainer with which you can learn your vocabulary in a structured and lasting way.
The VokabelBox is limited to 50 words for testing. If you want to learn more vocabulary, you can remove the limit at any time by purchasing an in-app-purchase.
Learn your vocabulary with three different exercises:
- Exercise
- Vocabulary test
- Card box
With the exercises, you playfully add new words to your vocabulary. You either have to choose the correct translation from a series of suggestions, find the correct word pair, choose the initial letter or put the letters of the translation in the correct order. Your learning progress is shown in a diagram at any time.
The vocabulary test prepares you ideally for your next exam. If you have made mistakes, you can repeat the wrong answered vocabulary immediately, or you can start a test with new vocabulary.
The card box helps you to consolidate your vocabulary in your long-term memory. The card box has six compartments. The aim is to bring the vocabulary to the last compartment. If you make a mistake, the vocabulary goes back into the first compartment. The learning distance increases with each compartment.
Overview of the learning gaps:
Box 1: immediately
Tray 2: 4 days
Box 3: 7 days
Box 4: 14 days
Box 5: 60 days
Box 6: every 180 days
(You can adjust the gaps to your needs)
With the folders you can structure your vocabulary and learn in a systematic way. For example, you can create a folder for a learning a book, then add a folder for each chapter and a box with the individual lessons for each chapter. So you can learn a single lesson, a whole chapter or even the whole book.
Book (folder) -> Chapter (folder) -> Lessons (box with vocabulary).
Not only can you create new vocabulary lists directly in the app, but you can also easily import them into the VokabelBox on your PC using your spreadsheet program. You can find instructions for this here: www.vokabelbox.com/xlsx-import
The app contains no vocabulary.
With the backup file you can save all your vocabulary along with your learning progress or transfer it to a second device.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
