What about Bitchat?

It is complicated. He says true. And maybe your need to use GrapheneOS is relevant. If you have a smartphone without cellular connection, for a daily usage, FMPOV it is a non-sense in case of emergency. It is a risk you will have to take, I can’t disagree your dad. And what about your solution but with a SIM card with very few data and SMS available, through a SIM card you can keep aside your phone and insert when needed?

Anticipate technical debt and follow what Google recommends. In few words, use Kotlin and Compose.

However you should really have a look on Google guidelines. In more worlds:

• by default Kotlin and Compose
• if some logic to share between other projects in other environments: Kotlin Multi Platform (KMP)
• if shared UI: Flutter (but Google reduced Flutter teams and KMP is being better and better, so we can suppose Flutter will join the Google Graveyard

Did you have a look on Cake Wallet app? Open source under MIT license and available on F-Droid.

Yep, it seems it is, but it can manage KDBX files. Just wanted to share 😄

Edit: sorry, didn’t see this thread is in Android community, my comment is not relevant for this platform.

You can use also for example Strongbox (https://github.com/strongbox-password-safe)

Edit: sorry, didn’t see this thread is in Android community, my comment is not relevant for this platform. For Android I am used to Keepass2Android (https://github.com/PhilippC/keepass2android). Simple, still maintained, under libre licence GPL 3.0.

It is always the same issues in fact. You should consider your threat model before all. Then, consider the Signal app, then your iPhone supposed to be updated, trusted, with ADP enabled, biometric lock with erasure after 10 failures, etc. Then consider your ISP, then your country. Etc, etc. You should also compare the contexts. Is an iPhone “better” than a low or middle ranges Android-powered smartphones? For sure, yes. Is it better than high-range expansive smartphones with Android ? Or Pixel ones? Not that sure. And compared to GrapheneOS or /e/? Pretty sure not that much. You can also compare messaging solutions. Is Signal better than WhatApp? Of course yes. But what about XMPP and Matrix for example?

And what are your use cases? Remember your threat model. If you are an activist, a journalist or a whistleblower your needs may be different than a “commons citizen worried about its privacy.

In few words, the only pain point I see is the fact than iOS is proprietary and runs non libre source code and Apple devices than APN. But Android devices are not so much different. It does not mean the solution is not private or efficient, if we succeed in defining a definition of “private or efficient”.

In a nutshell, it could be considered as good. But not perfect.

Any ideas for E2E encrypted storage alternatives?

Have a look on Organic Maps (https://organicmaps.app) or OSMAnd for example (https://osmand.net/).

Interesting. Thank you for sharing, didn’t know openhub!

Why did you say Write Freely seems to be dead? According to their GitHub organisation repositories, the backend has a release tagged 4 months ago and the iOS app 3 months ago.

Interesting! Do you remember where you got this chart?

You can for example have a look on the online resource below:

https://www.securemessagingapps.com/

It is very interesting with a big comparison grid between plenty of messaging solutions.

Why not using Firefox, Firefox Focus or Brave?
