khazan is a chat app that needs no SIM, no Wi-Fi and no account. Phones relay for each other over Bluetooth, so a message crosses a work site by hopping from phone to phone until it arrives. If one phone in the chain still has internet, the message continues out to a supervisor far away. One tap on SOS raises a loud alarm on every phone in range. Messages are end-to-end encrypted and never stored on a server, because there isn't one. Built for workers who lose signal: tanks, basements, tunnels.
Three free tools for travellers - no sign-up, no e-mail, no limit.
1. Do I need a visa? The tourist rule for your passport and destination: visa or not, the stay allowed, the passport validity, the official portal.
2. Visa-free countries: every destination your passport enters visa-free, with the days allowed.
3. Entry restrictions: which countries restrict your passport, full or partial, with the legal basis.
Every answer is dated, and non-official sources are labelled.
Your phone knows the filenames. Phondex knows what's inside them.
It reads the text inside your photos, screenshots, PDFs, Word and Excel files and makes all of it searchable — Arabic included. One search box across everything, with the matching line shown right in the result. Then open, share or delete the file from there.
Everything runs on the device. No account, no upload, no server — it works in airplane mode. Free.
