ForwardX is an Android app that automatically copies messages from one Telegram chat into another, using your own personal Telegram account rather than a bot. It is free to download as an APK file, with no ads, and runs continuously in the background once set up, so forwarding keeps happening even when you are not actively using the app. To use it, you first grab your own Telegram API keys from Telegram's developer site, my.telegram.org, then log into ForwardX with your phone number and those keys. The README is explicit that your credentials stay only on your phone and are never uploaded anywhere else. You also need to allow the app to send notifications and to ignore battery optimization, since Android otherwise tends to shut down background apps to save power, which would stop forwarding from working reliably. The core idea is built around three concepts: a source chat you copy messages from, one or more destination chats you send them to, and a rule that connects a source to its destinations along with any filters you want applied. Setting up a basic rule is meant to be simple: name it, pick a source, pick a destination, save it, then flip a single toggle on the home screen to turn forwarding on or off. Rules can also be tested safely before going live, since a test mode lets you check a rule without actually sending anything. Beyond the basics, rules support more advanced options, including priority ordering when multiple rules watch the same source, an option to stop lower-priority rules once a higher one matches, a choice between forwarding a message with its original "forwarded from" label or sending it as a fresh copy, and filters for specific message types like text, photos, videos, documents, or audio. The app also supports backfilling older messages that were sent before a rule was created. The project's license is listed as proprietary rather than open source, meaning the code itself is not freely licensed for reuse even though the compiled app is free to download and use.
