Constraint-aware cylinders
Scroll one segment while the others stay locked. The app narrows the available rows to combinations that exist in the dataset, so discovery stays meaningful.

Let Cyrus teach German with a cylinder you can actually turn.
Cyrus Cylinder turns German word-building into a tactile lesson. Spin through prefixes, middles, and suffixes, discover valid combinations, hear pronunciation, and learn meaning without wading through flat flashcards.
3 cylinders
Prefix, middle, and suffix align into real German words.
11 languages
Meaning readouts can be shown in multiple translation languages.
Built-in audio
Hear the German word and the translated meaning on demand.
Designed around separable German verbs
The app focuses on combinations that matter: when one segment stays fixed, the other cylinders only show options that actually belong with it. That keeps exploration fast and accurate.
What makes it different
This is not a card deck wearing a German flag. The entire interface is built around turning word parts, seeing valid outcomes instantly, and hearing the result in context.
Meaning below the alignment
Each valid combination reveals its meaning immediately underneath the cylinder, reducing friction between experimenting and understanding.
Word and meaning audio
Tap the speaker icons to hear both the German word and the translated meaning. Auto-read can also be enabled in settings.
How learning works
Cyrus Cylinder uses the tension of mechanical alignment to make vocabulary exploration memorable.
1. Fix one segment
Keep a prefix or middle stable and scan the remaining options vertically, exactly where the combination logic is strongest.
2. Read the meaning instantly
The assembled word and translated meaning update together, so each spin becomes a compact lesson.
3. Repeat with sound
Reinforce memory with TTS playback for both the German form and the target-language meaning.
Built for quick, repeatable practice
Use the random word feature when you want a prompt, or spin manually when you want to inspect how a verb family behaves.
Translation choices
Meanings can be shown in English, French, Italian, Polish, Ukrainian, Russian, Farsi, Arabic, Hebrew, Spanish, and Catalan.
Notifications
Users can enable reminders when another try unlocks, with refill timing managed inside the app.
Cross-platform release
Cyrus Cylinder is built with React Native and Expo for both Android and iOS deployment.
