OnionPhone is a native Android application for anonymous, end-to-end encrypted push-to-talk voice and text communication over the Tor network. No servers, no accounts, no phone numbers — your .onion address is your identity.

Cross-platform compatible with Terminalphone — call between Android and Linux/Termux using the same protocol.

Optionally use your connection as a relay for ephermeral group channels.

Find the release page for version 1.0.2 which supports custom bridges for accessing censored networks.

Probably a bad idea to congest the limited bandwidth of Tor with voice chat.

Yeah, unless they use specific nodes given by the community, i think it’s a bad idea

Extremely annoyed at devs who think everyone has Android phones when most people in the US have iPhones. Making an app incompatible with the majority of smartphones means you have not made an app

The bandwidth is low by design. I’ve excluded files and images to keep it down as well. You could talk ²⁴⁄₇ only use MBs.

If we want Tor to grow we need useful applications useful for everyone. I doubt this will be widely adopted.

I’ve contributed a large amount of bandwidth to the network so why can’t I use some?

Be mad at apple. This application would never work. To many gate keepers.

What’s the selfhosted component of this?

Self hosting your own private P2P voice service.

Optionally use your device as a Audio relay for group calls, in which case you become the ‘server’ to all connected clients.

I am extremely annoyed at users that think everyone has iOS phones, when most of the world have Android. Thinking that the US is the only relevant place means you have serious tunnel vision. /s

Oh an blame Apple. They are extremely hostile to open-source devs publishing apps on their platform.

Not OPs fault you’ve picked the wrong os ¯\(ツ)/¯

Lol. Your post is pure US defaultism. The US only has 5% of the world wide population. Worldwide Android has around 71% market share while iOS only has around 27%.

Be better mister American.

Plain speech can be compressed pretty well. I’m not an expert by any means, but I suspect latency would be the bigger issue.

Latency is a huge issue, but it goes away with the PTT model. I tried full duplex on initial prototyping but it was trash.

PTT forces solves this by simply forcing the listen, digest, then respond. You can expect about 2-3 seconds of delay from when you release the ptt, to when the other side hears it.

It’s roughly split in OS in US. I fell most security conscious users are android users. Sold might initially give slightly better initial privacy, android is far more customizable to the point there’s no contest.

Plus, I buy my phones outright so I’m not stuck with a $1000+ phone in a contract or subsidized phone plan making payments.

Self hosting […] P2P

You do realise that’s a contradiction.

Unless you’re hosting a TOR node (which is outside of the scope here and, depending on the node and jurisdiction, extremely risky), there’s nothing here that’s relevant to self-hosting.

I don’t agree with that. Both sides are acting as a server and a client, connecting via a onion service to either parties rendezvous. And then when you include the fact that you can become a relay, that is clearly self hosting a server in a pure sense.

There are no exit nodes involved in onion services. It all stays within the network.

If Apple didn’t keep treater smaller developers like shit, maybe you would have more options for applications that respected your privacy and weren’t as monetized.

Consider moving away from the abusive platform and then your options for privacy and security will expand. Maybe look for a phone with GrapheneOS support (previously only Pixels, but Motorola models will come with support soon) for complete control and customization.

This is sick! Thanks for sharing your project with us! I would have never guessed you could do voice over TOR but PTT was a clever solution. Its like the old nextel phones that had PTT. I wonder if its possible to remap the volume button to be a hardware PTT button.

Android has a huge market share compared to iOS, plus it’s a lot harder to develop these types of applications for iPhone because of apples policies.

This right here - plenty of good android phones out there that don’t need contract financing.

Especially now that Motorola is gonna partner with GrapheneOS.

Happy to contribute! So, currently (only while in the app for now) you can activate the mic with a double pressdown on volume if the setting is enabled.

My attempts to trigger the mic while outside the app came with a few unwanted side affects so I removed it for now until I find a solid way to do that.

Creating more mainstream use-cases is how you get people to donate more bandwidth.

Extremely annoyed at users who expect FOSS devs to go through the rigamarole of paying the Apple tax, and getting Apple’s permission to have the privilege of making it available to their customers.

This is stupidly cool omg

Buys closed eco system phone. Shocked it’s a closed eco system. Cue shocked Pikachu face?

Check the global total deployments, US is not the only place in the world with smartphones.

😂 lol, lmao even 😂

I had Pixels for me and spouse. Bot had poor screens (broken / white lines). Now we have Moto phones. I would love to have Graphene on the next one.

It goes even beyond that, their comment is just wrong on multiple different levels

Wow so awesome going to try it out.

Nice a real step forward for private communication.

Would be awesome if it ever has a messaging section without having to make a call, still, an awesome start!

This is extremely cool.

most of the world have Android

Heck, most of the Known Universe.

I’ve put some thought into this. The biggest roadblock to P2P is ²⁴⁄₇ persistence. You have to be online.

I think the most straightforward path to this is having the ability to setup a mailbox sort of how the relay works but on a machine that’s on a ²⁴⁄₇ stable connection. Because it’s already cross compatible with Linux systems, it would make the most sense to have a dedicated mailbox there, and have it forward your messages that were missed while you were offline.

Once the mailbox is set up, it’s just a matter of tieing the separate mailbox identity to forward messages to you once your online. Ideally integrate tors built in authorized client protocol to ensure only one person is authorized to the mailbox.

Super cool!

convenient in one app, but we already have briar for that

What a small world! I made a TOR P2P messaging app using symmetric encryption POC in college! I was just getting around to re implementing it into something more polished!

Get a android you lunatic

why go with tor and not with i2p?

I think this is the most downvoted comment I ever saw on lemmy. Gratz.

Omg! I was just looking for a walkie talkie type app!

How does a regular person donate bandwidth?

By partaking in it.

tor is actually a bit more secure than i2p from my understanding. mostly it has to do with the routing, which is both the strength and weakness of tor.

I would like to test a garlicphone varient. I’m not opposed to i2p, I am just alot more familiar with Tor integrations than i2p.

Onionphone uses prepackaged binaries from the guardian project. https://github.com/guardianproject/tor-android.

I would basically need to find the same thing, but for i2p.
