Quicksy is a spin off of the popular Jabber/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. Under the hood Quicksy is a full-fledged Jabber 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 +phonenumber@quicksy.im 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. Suggested contacts consists of other Quicksy users and regular Jabber/XMPP users who have entered their Jabber ID into the Quicksy Directory (https://quicksy.im/#get-listed). NOTE: To enter (https://quicksy.im/enter/) your Jabber ID in the Quicksy Directory an one time registration fee is required. Read the Privacy Policy (https://quicksy.im/#privacy) for more info.

Quire is a native Android EPUB reader for people who self-host calibre-web.

Features: - OPDS catalog browsing and search - EPUB reading with Readium (font, theme, line-height controls) - Reading progress sync across devices via your own Postgres - Multi-user from day one - One credential: your existing calibre-web account Privacy: - No analytics, no crash reporting, no third-party SDKs - Network calls go to your calibre-web and your sync server only - Credentials stored in Android Keystore Source code, server, and documentation: https://github.com/vitofico/quire Optional AI features (off by default): when your Quire Server administrator configures an AI endpoint (such as a self-hosted Ollama or a third-party provider) and you opt in from Settings, Quire shows generated book insights — author, summary, series, themes, craft notes, comparative anchors, and book-club style discussion prompts — grounded with citations from Wikipedia and OpenLibrary. A separate Library Insights screen builds a personal reader profile from your finished books and suggests further reads (both from your own library and via OpenLibrary discovery). No AI request leaves your network until you explicitly opt in, and a single tap in Settings deletes the cached profile.

Receive live traffic news via Traffic Message Channel (TMC) Qz (pronounced “queues”) connects to an RDS/TMC receiver to receive live traffic messages. TMC is transmitted in the RDS data stream of various radio channels and provides live traffic information, helping you avoid congestions. For a list of countries in which this app can be used, see https://gitlab.com/mvglasow/qz/wikis/countries. In order to use this app, you will need a supported RDS/TMC receiver. The following devices are currently supported: * GNS FM9-BT (requires Bluetooth) * Silicon Labs Si4701/4703-based USB tuners (requires USB OTG support) If you are unable to pick up any traffic messages, despite having a supported device and being in an area which should be supported, check your antenna. Reception with pigtail antennas (a long piece of wire coming out of the receiver) is generally poor and insufficient for TMC. It is recommended to rely on your vehicle antenna, a building antenna or a somewhat decent room antenna. Qz will only work with unencrypted TMC services (as encrypted services require paying a per-device royalty). Also, some countries have chosen to require paying a royalty for access to their location tables (which Qz needs to decode TMC locations) and are therefore not supported.
