Network Survey+
APK
FOR ROOTED ANDROID PHONES WITH CERTAIN QUALCOMM CHIPS ONLY.So far, the only device that this app has been tested against is a Pixel 3a. Other devices will be added at a later date.The Network Survey+ app is the "advanced" version of the regular Network Survey app. NS+ accesses the Qualcomm diag device to get QCDM messages. The QCDM messages are then processed and logged to a pcap file. Currently, only LTE RRC OTA messages are processed and logged. In addition, each pcap record is geotagged with the device's current location.The pcap files can be opened and viewed in Wireshark.This app also supports streaming the LTE OTA messages over an MQTT connection. See https://messaging.networksurvey.app/#operation-publish-lte_ota_message for details.Note that this app only works on rooted Android phones, and requires a cellular qualcomm chip that exposes the /dev/diag device and supports QCDM messages. See https://github.com/christianrowlands/android-network-survey-rooted for a list of compatible devices.See https://mosquitto.org for information on setting up a MQTT Broker.

If the nextcloud client is installed and you want to synchronize direct with the nextcloud server, you can use the login button to show a list of accounts and you choose the account to login. Then the app will download the recipes with the REST api. If you want to synchronize with the local storage, you can skip the login ("Skip for local storage"). After that, you have to choose the recipe directory in the settings and permit access. In the app "All categories" is the main view, there the app is loading the recipes from the choosen directory. When using the Nextcloud Android client, you find the directory on your storage under Android/media/com.nextcloud .client/nextcloud/<your account>/<folder>. You also can choose the theme in the settings. After that, the start view has a list of recipes and you select a recipe to view the details. IMPORTANT: With direct pick of the nextcloud folder there will no images shown and the uri can't be stored right. Perhaps at next app start no recipes can be loaded. Therefore it is better to use the above mentioned path on the SD card (see First steps).

NymVPN – Anonymous No-Log VPN
APK
NymVPN: the world's most private VPN. A secure, decentralized, anonymous Swiss dVPN with no logs. WireGuard speed, Noise Generating Mixnet anonymity. No email signup. No ads. 🎁 7-DAY FREE VPN TRIAL & PLANS FROM $2.39/MONTH Try free for 7 days, no commitment. Pay in crypto, card, or cash: your choice. 🛡 PRIVACY BY DESIGN Most VPNs say 'no logs' as policy — they can log, they promise not to. Free VPNs track you to sell your data. NymVPN's architecture makes meaningful traffic logs impossible: our decentralized, anonymous network of servers routes your traffic through multiple hops, so no single server sees who you are AND what you do. Even Nym can't connect your identity to your activity. No logs to hand over: none to keep in the first place. ⚡ TWO VPN MODES, ONE APP • Fast Mode: AmneziaWG (WireGuard)-based 2-hop dVPN. Fast streaming and browsing on a decentralized network so no single operator can log you. • Anonymous Mode: 5-hop Noise Generating Mixnet, a more private successor to Tor. Routes your traffic through independently operated servers, mixes your packets with others, and adds noise and cover traffic to defeat traffic analysis. The most anonymous consumer VPN available today. Perfect for crypto, email, and private messaging like Signal. 💰 PAY ANONYMOUSLY WITH CRYPTO OR CASH NymVPN accepts more cryptocurrencies than any other VPN, plus cash payments. Pay with Bitcoin (BTC), Ethereum (ETH), Monero (XMR), Zcash (ZEC), USDT, USDC, NYM, and many more. Zero-knowledge credentials delink your payment from your VPN use: pay anonymously, use anonymously. 💎 WHY NYMVPN IS DIFFERENT • Zero-knowledge architecture: your identity invisible even to Nym • No logs by architecture: the network can't keep meaningful traffic logs • Decentralized proxy network: no central server can compromise or surveil your traffic • Swiss jurisdiction: outside the 14 Eyes, protected by strongest privacy laws in the world • WireGuard and mixnet protocols: a fast VPN + the most private way to be online • No email signup: no personal data required • Fully open source: audited by independent security researchers • 70+ countries: servers worldwide for global streaming and access • Up to 10 devices on one account 🔒 PRIVACY & SECURITY FEATURES • Built-in kill switch: automatic traffic stop if the VPN connection drops • Censorship resistance: prevent VPN blocking and access the global internet with QUIC, AmneziaWG, and other techniques • Multi-layer onion encryption • Entry & exit server selection • Split tunneling: route only the apps you choose through the VPN • Custom DNS: use any DNS server you trust • Ad and tracker blocker 🌍 WHAT YOU CAN DO WITH NYMVPN • Browse anonymously without leaving a trace • Encrypt your traffic on public wifi at airports, cafes, hotels • Bypass internet censorship in restrictive regions • Protect sensitive communications for journalism, activism, and research • Stop ISPs from profiling your browsing for ad targeting • Block malicious websites, trackers, and ads at the DNS level 🇨🇭 SWISS PRIVACY, BY DESIGN NymVPN operates under Swiss law, with the strongest privacy protections in the world. Switzerland sits outside the 14 Eyes surveillance alliance, with constitutionally protected privacy rights and no mandatory data retention. With a decentralized, no-logs architecture, your data is protected by both law and design, not by a promise. 🎓 BUILT BY ACADEMIC CRYPTOGRAPHERS NymVPN is built by Nym, trusted by journalists, activists, and privacy-conscious users worldwide. Our protocols are open-source and audited by independent security researchers. 🚫 WHAT WE DON'T DO • We don't ask for your email or your name • We can't track which sites you visit • We can't sell, share, or rent your data 📲 GET STARTED Download NymVPN, create an anonymous account without an email or even a name, and start browsing privately.

Even encrypted data can leak metadata. Nym is designed to prevent that. - Noise Generating Mixnet technology: In Anonymous Mode, your traffic is mixed with cover traffic across multiple hops, making correlation and AI-driven traffic analysis extremely difficult. - Two privacy modes, one app: Fast Mode uses a high-performance 2-hop decentralized VPN. Anonymous Mode uses a 5-hop mixnet for maximum anonymity. - Zero-knowledge accounts by design: No email signup. No personal data. Accounts are unlinkable from usage.
