📝 About this app
Diese App macht Ihr iPhone zum praktischen Brevier für unterwegs und lädt ein, den uralten Gebetsschatz der Tageszeitenliturgie neu zu entdecken, wie ihn die Priester und Ordensleute seit Jahrhunderten beten. Ideal auch für Anfänger, da kein Zusammensuchen der Texte notwendig ist. Die Texte werden jeweils für zehn Tage im Voraus auf das Gerät geladen, so dass man anschließend das Brevier auch ohne Netzempfang beten kann. Eine Ein-Finger-Lesehilfe erlaubt eine diskrete Bedienung und hilft, sich auf die einzelnen Verse zu konzentrieren.… View full description on the official store →

About this analysis
Why low confidence: only 8 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Stundenbuch is a early-stage iOS app in the food & drink space with weak public traction — only 8 ratings, no founder-verified MRR, and not ranked in any monitored grossing chart. The app appears to be monetised, but public signals are too sparse for a precise revenue estimate.
Bottom line: treat all revenue, audience and acquisition-value numbers on this page as directional only — not founder-verified facts.
