Comments on 39C3 Schedule for Android

★★★★☆ Martin Breuer · Dec 27, 2018

Super bien! Feels a bit slow / unresponsive / laggy on Huawei P10 with Android oreo

★★★★☆ Simon Struck · Dec 28, 2018

A bit slow when returning from event description to the planner, otherwise amazing. I'd like to be able to only get schedule updates that actually affect me.

★★★★☆ Zimt Gewürz · Dec 27, 2025

Thanks for this neat app, very helpful! Just 2 improvement suggestions: 1) could you maybe add a toggle to deactivate the popups that inform about the updates? 2) Same for the popup that suggests rotating the phone. If you could offer options to remove those dialogs and make it more distraction-free I think a lot of the neurodiverse audience would appreciate it. Thanks a lot and have an excellent congress!

★★★★☆ aschmitz · Dec 28, 2018

Good, and fast updates are nice, but I would have liked the ability to search talks, or show more than one room at a time.

★★★★★ Martin Wiegand · Apr 18, 2020

Very useful. Looking forward to future versions and congresses.

★★☆☆☆ R. Rubesch · Dec 29, 2018

Very slow, especially when pressing back button in any situation
