About this APK

Quicksy is an app by Daniel Gultsch in the Communication category, listed since at least March 2021. It includes native code only for ARM 64-bit, so it won't install on phones that can only run 32-bit apps.

Since version 2.13.4+playstore, the APK grew from 13.1 MB to 22.3 MB and the minimum Android version rose from 5.0 to 6.0. It asks for 45 permissions, 9 of them sensitive, including precise location, camera and record audio. It asks for the same permissions as version 2.19.13+playstore.

What's new in v2.19.15+playstore

• Fix Quicksy registration on older devices • Show warning in chat if contact is in different time zone and it is night time for them • Show warning in chat if contact is DND • Refactor automatic DND handling (based on system DND)

Description

From the listing uploaded by “appupdater”.

Quicksy is a spin off of the popular XMPP client Conversations with automatic contact discovery. You sign up with your phone number and Quicksy will automatically—based on the phone numbers in your address book—suggest possible contacts to you.¹ Quicksy can be downloaded for free from Google Play Store. The source code is licensed under the GPLv3 and available on Github. Under the hood Quicksy is a full-fledged XMPP client that lets you communicate with any user on any publicly federating server. Likewise users on Quicksy can be contacted from the outside simply by adding [email protected] to your contact list. Aside from the contact sync the user interface is deliberately as close to Conversations as possible. This allows users to eventually migrate from Quicksy to Conversations without having to relearn how the app works.
