Quicall vs Tysha

We, humans, have natural ways to communicate. We say things to each other in private, then we forget over time. Quicall is here to do that digitally. Quicall is fully encrypted end-to-end. All your messages, whether it's a 1:1 chat or a group chat, are fully encrypted in-transit or at rest. Quicall does NOT store your messages, not on the server side, and not on the client side. You can choose to store messages for 1, 7 or 30 days. After which, the messages are gone. There are no permanent storage options. Quicall does not store metadata. Metadata often reveals more than the contents of the messages themselves. Quicall prefer not to know that. Once a message is delivered, no other info about the message is kept. Quicall does not require a phone number. You should be able to chat with others without disclosing your phone number. You can register on Quicall with an email address. And you can disable people's ability to find you by email. Quicall is not designed for viral growth. It is not easy for people to find you. You can invite or connect with friends with a unique link or QR code. Quicall is designed so that only your friends can find you. Quicall is open-source. We believe secure apps should be transparent in how they work. Quicall is free. No ads. Quicall does not collect or sell data.

Tysha is a messenger that starts with a nickname you invented, not with your phone number. Get it while it is free - the free ride will not last forever. NO NUMBER, NO EMAIL, NO PASSWORD An account is a username plus 12 words generated on your device. We never see them and store them nowhere. There is another side to that: lose the words and nobody can restore the account, us included. INTRODUCTIONS BY A ONE-TIME CODE Contacts come only from invitations. The app never reads your address book, there is no people search, and nobody can find you by number - there is nothing to search by. A code stops working once used, or after 15 minutes. ENCRYPTED ON THE DEVICES Messages and calls are encrypted on the devices themselves: the libsignal library, PQXDH key agreement (X25519 + ML-KEM-1024), Double Ratchet. Keys are created on the device and never leave it. IPHONE AND IPAD Tysha runs on iPhone and iPad. A second device is linked to your account with a code from the main one; every device has its own keys, and they never leave it. The main device manages the account, and a linked one can be unlinked at any time. All your conversations stay encrypted. Security does not break. WHAT THE SERVER GETS A sealed envelope: bytes, size, time and a queue address - 32 random bytes with no link to your username. It never sees text, files, the sound of a call or an address book. No ads, no third-party analytics, no profiling. WHAT IS INSIDE - disappearing messages, from 30 seconds to four weeks - view once for photos and video - delete for both sides, not just your own copy - voice messages, files up to 64 MB, reactions, replies, edits - voice and video calls: relayed by default, so the other side never sees your IP address - group calls for up to five people, each pair encrypted separately - quick replies to an incoming call - a new glass look and alternative app icons - small groups with sender keys - a Face ID lock and a wipe after too many wrong codes - your own ringtone, 12- or 24-hour clock, Ukrainian and English WHAT IT COSTS Free for now. No ads, no in-app purchases, no subscriptions. So get it while the ride is free - it will not stay free forever. WHAT WE DO NOT PROMISE The lock protects the screens; it does not re-encrypt the store. A screenshot notice cannot stop someone photographing the screen. Disappearing messages cannot stop someone copying the text first. Each of these limits is stated inside the app itself.
