Halm vs Data_Engineering

Read something you actually want to read — in German or English — and let the words stick. Halm turns short stories and adapted news into reading you can handle at your level. Tap any word to see what it means right here, in this sentence. Keep the ones worth keeping. EPISODES Multi-part stories set where you'd actually be: an apartment viewing, a doctor's waiting room, a Sunday at the lake. Each episode shares vocabulary across its parts, so words return on their own instead of being drilled. TAP ANY WORD Translation runs on your device. Halm reads the whole sentence, not the word alone. KEEP WHAT MATTERS You choose what enters review. Nothing is added behind your back. Kept words return on an FSRS schedule, and Halm shows you counts you can verify — never invented percentages. GERMAN AND ENGLISH Two full tracks. Pick one, or switch whenever you like. NO STREAKS Nothing to break, no leaderboard, no notification guilting you back. Read when you want to read. PRIVACY No account, no sign-up, no third-party analytics or advertising. Halm collects nothing automatically. ACCESSIBILITY VoiceOver throughout, Dynamic Type everywhere, Reduce Motion honored, and color never used as the only signal. Works offline. Requires iOS 26.
