3DM Viewer opens a CAD file on the phone, draws it, and lets you turn it around. It is a viewer and nothing else: there is no editing and no save path anywhere in the program, so it can never write over the file you opened. Everything runs on the device - no network, no telemetry, no cloud.

iWifi turns a Sailfish OS phone into a passive Wi-Fi security checker: a heading-up radar of the access points around you, a per-hotspot security assessment, CVE lookup for the router model, and an optional monitor mode (external USB adapter) that defensively detects deauthentication attacks and evil-twin APs. It never transmits, injects, cracks or decrypts anything.

iNFC is a native NFC app for Sailfish OS that reads, identifies, stores and emulates NFC tags and smart cards. It talks to nfcd over D-Bus and never polls in the background: the radio stays off until you pull down and choose Read.

iBT — a passive Bluetooth / BLE observer for Sailfish OS

iBT turns a Sailfish OS phone into a strictly passive Bluetooth / BLE security and analysis tool. Using only the phone's own radio (via BlueZ), it listens to the advertising data that nearby devices broadcast anyway and makes sense of it — without ever transmitting, connecting, intercepting, attacking, logging or exporting anything.

Developed and tested on a Sony Xperia 10 III (pdx213). Much of it should work on other Sailfish OS devices too, but the Xperia 10 III is the reference device.

What it does

SF-Mail is an unofficial, security-friendly e-mail client for Sailfish OS with built-in OpenPGP and S/MIME. Its goal is to make encrypted e-mail genuinely easy: encrypt, decrypt and sign mail (PGP/MIME, inline PGP and S/MIME), including encrypted attachments. Accounts, folders and messages come from the system mail database, so the app sits next to the stock mail app and shares its accounts. "SF" is not short for Sailfish - it stands for making security friendly.

SailWarden - Bitwarden Client for Sailfish OS

SailWarden is an unofficial native Bitwarden client for Sailfish OS. It is currently in beta and requires Sailfish OS 4.5 or greater. This app has near one-to-one feature parity with the official Bitwarden apps. That means most functions you know and love from Android or iOS should be available here with a few exceptions that aren't available on Sailfish, like autofill or syncing with authenticator.
