Hey PH! 👋
I'm Chirag, solo developer and the developer of GermanVault.
I built this because I was learning German myself and kept switching between five different apps — none of them had everything. So I spent two years building the reference I wished existed. I have lived in Germany for more than 10 years and contents of the app are originated mostly from my knowledge and experience.
What makes it different:
— Full conjugation tables for every tense (all 9), not just present
— AI quizzes that generate fresh questions server-side with Gemini
— Real idioms and slang, not just textbook vocabulary
— Scenarios: immersive situational German (job interview, doctor, Ausländerbehörde)
— Gamified sentence builder and Der/Die/Das game with lives + timer
It's free with no ads on the core content. Premium unlocks unlimited word collections and AI hint credits.
I'd love to hear what you're building or learning. Happy to answer anything about the tech stack (Ionic/Angular/Firebase/Capacitor) or the language-learning design decisions. 🇩🇪

Finally an app that doesn't scatter German across five different tools. The 9-tense conjugation tables are surprisingly clear and the streak system actually made me come back the next morning.

@enginmoro Thank you Engin! That "one vault for everything" problem was exactly why I built this — I was tired of switching between tabs just to look up a conjugation while reading an idiom explanation somewhere else. Really glad the streak is doing its job too, that second-morning return is exactly what it's designed for!

love that you nailed the 9-tense conjugations in a clean swipe format. so many apps stop at 6 and leave you guessing on Präteritum vs Plusquamperfekt, this actually closes that gap.

@gamzewxea Thank you Gamze! Präteritum and Plusquamperfekt are genuinely the tenses that separate different levels — stopping at 6 just leaves a cliff edge right when things get interesting when you level up. Really glad the swipe design makes it digestible rather than overwhelming!

the offline access on a free tier is a really thoughtful call, especially for commuters. love that the conjugation tables go all the way to 9 tenses without burying them behind a paywall.

@salimtemencska Thank you Salim! The commuter or poor-network area use cases were front of mind — patchy underground signal shouldn't interrupt a study session. And agreed on conjugation tables: putting 9 tenses behind a paywall would defeat the purpose entirely, that's reference material everyone needs regardless of tier. Also, adding more and more Verbs will be in the pipeline too.

The verb conjugation tables are way more detailed than anything else I've tried, and the offline access actually works on the subway where I usually study.

@asyagulerm7389 Thank you Asya! The subway and weak network areas use cases are literally why offline was a day-one priority — I tested every early build on the tube and if it broke without signal it didn't ship. Really glad both the depth and the offline reliability are holding up in real conditions!

One thing I'd love to see is a shadowing mode where I can hear a native speaker say a sentence, repeat it back, and get feedback on my pronunciation. Right now the app seems focused on reading and writing, but actually speaking is the hardest part for me and I'd happily pay extra for that.

@esranldf This would be genuinely one of the most-requested features and honestly one I want to plan & build too — you're right that speaking is where most learners plateau. I've been researching TTS + speech recognition options that would make it feel real rather than gimmicky. Adding it to the roadmap with your name on it 😄 Would a "repeat after native speaker + record yourself" format work for you, or were you thinking more real-time feedback on pronunciation accuracy?
