Seitdem geht auch nichts mehr in die Bibliothek. Dann halt nicht. Es ist mir schleierhaft, wie man aus so etwas gutem, so schnell einen Haufen Mist machen kann. ### 1/5 — Vieles fehlt *2026-01-02* Leider ohne Anbindung an Apple CarPlay. Schlechte Software. Es gibt noch nicht einmal ein Merkliste, in die ich interessante Bücher legen kann. Sehr schade. So wird das keine Konkurrenz zu Blinkist… ### 4/5 — Interessant mit Sprachfehlern *2025-09-28* Die Themen sind spannend und abwechslungsreich! Aber warum um alles in der Welt wird das Wort „bei“ nicht gesprochen sondern b-a-i buchstabiert??? Das bringt mich beim zuhören völlig aus dem Konzept und scheint ein durchgängiger Fehler zu sein. Bitte die KI entsprechend anpassen. Danke ### 5/5 — Love it *2025-09-14* Perfekte Länge, um schnell aber trotzdem ausführlich über möglichst viele Themen/Bücher informiert zu werden! ### 2/5 — Angestrengtes Vorlesen statt Wissensvermittlung mit Leichtigkeit *2025-09-14* Angestrengt und überdeutlich vorgelesen, ohne Leichtigkeit und Spaß in der Stimme. Widersprüchlich für mich, wenn über die App Inhalte schnell und leicht vermittelt werden sollen. Zumal die Zusammenfassungen teilweise wie ein lockeres Gespräch zwischen Sprecherin und Sprecher geschrieben sind, aber eben hölzern vorgelesen werden. Blinkist gefällt mir da besser … alleine aufgrund der Profisprecher. ### 5/5 — Great app for hustlers!! *2025-09-13* This app is a game-changer for anyone who wants to learn fast without wasting time. The 15-minute narrated book summaries are super engaging and easy to fit into my day, whether I’m commuting, working out, or taking a short break. The real-time AI chat with the book is incredible — it feels like having a tutor on demand whenever I want to dive deeper into a topic. The library is well curated with high-quality content on business, tech, and science, and the mini-player makes it smooth to resume where I left off. Perfect for busy people who want to keep growing every single day! ### 5/5 — Alles gratis für mich *2025-09-09* Spitzen-App! Hab mir jetzt etwa zehn Bücher angehört. Einige davon hatte ich vorher gelesen. Hier kann ich also ganz gut beurteilen: Die Zusammenfassungen sind präzise und richtig hilfreich. Ich hab ein Bild-Abo. Damit sind alle Titel für mich kostenlos. Mega! Gehört jetzt zu meiner Pendler-Routine: Auf dem Weg zur Arbeit schnell ein Buch weghören ### 5/5 — Super! *2025-09-08* Die 900s-App ist einfach genial! In nur 15 Minuten pro Tag bekomme ich kompakt aufbereitetes Wissen zu spannenden Themen wie Technologie, Business oder Wissenschaft. Die professionell gesprochenen Episoden sind super angenehm zu hören und passen perfekt in meine kurze Fokuszeit – sei es morgens beim Kaffee oder unterwegs. ### 5/5 — Endlich was zum Mitreden *2025-09-05* Also ich find die App echt klasse! Ich steh ja eher mit beiden Beinen im Alltag, hab nicht ständig Zeit für dicke Schinken. Aber hier krieg ich die wichtigsten Punkte fix serviert. Und wenn mein Mann wieder loslegt mit seinem „Weißt du eigentlich…“ – dann hab ich endlich auch mal was in petto. Macht richtig Spaß, wär nur schön, wenn’s noch mehr praktische Themen gäbe. ### 5/5 — Great quick fix *2025-09-05* A very handy tool for anyone who wants to get the key ideas of a book quickly and easily. ## Frequently asked questions about 900s ### What is the learning methodology of 900s? 900s uses a podcast-style learning methodology, breaking down complex topics into 15-minute audio episodes.
