In their own words
NULVEX
NULVEX is described on its supplied site as AndroidIRCx, an IRCv3-compliant client for Android. It connects to multiple IRC networks and servers at the same time, with channels, private messaging, server failover, IRCv3 capability negotiation, and DCC transfers. Direct messages and channels are listed as end-to-end encrypted with key verification, while IRC server links can use SSL/TLS. SASL handles server login. SOCKS5, HTTP CONNECT, and Tor proxies can be configured per network or globally. The app includes JavaScript scripting with event hooks, custom commands, and timers; scripting time can come from rewarded ads or become unlimited through a Pro purchase. Other tools include Bouncer/ZNC integration, a services panel for NickServ, ChanServ, HostServ, and OperServ, voice messages, camera and video capture, and encrypted backup and restore. Android 7.0 is required, with Android 11 recommended. Downloads are available through Google Play or a direct APK. The project is open source under GPL-3.0, with offline access listed. Google Play instead describes NULVEX as an encrypted notes vault, creating a product-description mismatch.
Turtl
Turtl is a collaborative notebook for organizing bookmarks, passwords, files, shopping lists, and other notes. It supports text, bookmark, password, image, and document notes, with full-text search, tag filtering, Markdown, and TeX math rendering. Users can create Spaces, choose collaborators, and set permissions from read-only access through full ownership. Turtl says data is encrypted in the app before leaving the device, using keys derived from the user's email and password. Shared items get separate random keys, so recipients can unlock only the item shared with them. The service warns that an intercepted email invitation could expose a shared Space if its secret is not communicated separately. Users can import or export their full profile for backup or migration, and can install the open-source server to host their own data. Listed platforms include Windows, macOS, Linux, and Android, with Chrome and Firefox bookmarking extensions; offline access is supported. Premium costs $3/mo and includes 10GB note data and 10 collaborators per Space; Business costs $8/mo and includes 50GB and dedicated support.
