eigentlich super App aber das Design ist nicht so gut als zum Design 1. ich würde eine Linie in neon blau zwischen Timeline und karlender machen 2. ich würde einen Pfeil neben die sall Anzeige machen mit der man dann zwischen den sällen wechseln kann 3.ich würde das heder in noch dunklerem blau färben und diese Schrift wälen Space Grotesque 4. ich würde alles etwas runder gestalten und die Ecken auch das war's auch schon LG

Great experience. But the update overlay is useless. It never shows any updates. Even ifbit states there are some. And in the Lockscreen in cannt be dismissed.

I'd prefer a single dynamic list of talks sorted by starting time and containing start time, end time, language, topic, room, and title. There should be possible to filter the list at least by topics, languages, and keywords in title/description. Then, the existing list of favourited talks should facilitate dealing with collisions. There is no need to worry about collisions before marking all favorite talks, because only then it is only possible to choose the most interesting talk.

Ohne die App wäre ich lost gewesen. Besten Dank! Ich wünsche mir noch eine Suchfunktion, wie bei der iOS-Variante.

Umständlich zu bedienen (auch in Landscape), macht aber, was sie soll. Funktionsideen: Import der Halfnarp-Auswahl, Talks nach Themengebieten sortieren, ausblenden von Stages Danke für die Antwort! Beim horizontalen Scrollen ist der "Lock" auf die Stages nicht nutzerfreundlich. Ich nehme beim Scrollen schon Informationen auf. Wenn ich loslasse springt der sichtbare Bereich. Der horizontale Schnellscroll wird unbeabsichtigt ausgelöst und springt eine unklare Distanz.

Ein Kunststück guter Programmierung. Schnell, praktisch und kleine Genialitäten integriert.

Sehr coole App, kannst Du auch ein white- ähm non-dark-theme anbieten? (dachte an etwas mittel-komplexes wie Hintergrund #FFFFFF 😁😂, Wesen mit 50+ kommen mit dunkel auf hell deutlich besser zurecht als chiquen Dark-Themes🧑‍🦯🦯) Sorry, aber minus 2 * wegen Accessability - ein Custom APK bauen zu müssen für einen hellen Hintergrund - echt schwierig.
