Hey! I wrote up a list of Open Source iOS apps on the Privacy Guides community.

I've been slowly trying to become platform agnostic, so I can switch back and forth between OSs without losing function. I'm not 100% there, but I hope this list helps you too if you are looking to go that route.

Ryan Cohen is also the founder of Chewy. His interest in GameStop is basically the reason it’s stock price took off.

Edit: After digging into 2FAS, I think it is now my top choice. Seems like more of a drop in replacement for Raivo. https://2fas.com/

My second choice is (as of this edit) Owky. I’ve not seen anyone talking about it, but it’s FOSS and has the ability to export your TOTP codes.

Im a little worried about it not being maintained though, since it’s a single developer.

https://apps.apple.com/us/app/owky-two-factor-authenticator/id1602245257

Other options I’ve considered:

Tofu Authenticator. Unfortunately it’s basic though and lacks the ability to export.

ente Authenticator. Account required, and I’m a little undecided on the company. Might be a serious option though.

Wow, somehow this escaped me all these years. I feel like I’ve got a bunch of fresh XKCD to read now.

For the uneducated: On a mobile browser you just press and hold the comic (long tap). On a computer you hover over the image and the alt text will appear next to the cursor.

The alt text in this one was:

::: spoiler spoiler Fortunately, the charging one has been solved now that we've all standardized on mini-USB. Or is it micro-USB? Shit. :::

I don’t feel like leaving the PG community at the moment, but here are a few suggestions that come to mind after reading your list.

Search: SearXNG

MacOS Firewall: Lulu

DNS: NextDNS

Email Alias: AnonAddy

2FA: 2 FAS, iOS and Android

2FA: Remove Ravio (sold to sketchy app maker MobiMe). I consider this compromised until proven otherwise.

YT Proxies: Yattee (iOS App)

File Encryption: Cryptomator (File encryption app, optimized for the cloud)

Notes: Joplin

Podcast: Podverse

Graphics: Digikam ente

Some feedback intended to be constructive, thanks for contributing to the process!

1. The gradient on the mouse is a bit too much for me. I would prefer it to look flatter. Compared to the look of most modern app icons, it’s just too 3D for my brain.

2. I like the tongue sticking out and the eyes, but my suggestion would be to slightly tone them down. Maybe make them smaller in size (eyes in particular)?

3. My personal preference is that the mouse take up a little more space in the icon, but that’s just nitpicking.

To add to this, I suggest sorting the comments by controversial on Reddit for another take.

Yeah, I'm not huge on the web3 stuff and P2P has some drawbacks in terms of function, but having the ability to message cross-platform over Bluetooth is amazing.

That being said, I'm not planning to switch over from Signal anytime soon for my primary communications.

I mean, they most certainly have the technical ability to hack anyone. If you think they don’t strategically stockpile and use zero-days, you aren’t paying attention.

Any reason for not just using PrivacyGuides.org instead? I like seeing a lot of variety, but PrivacyGuides seems like the cream of the crop in my opinion.

Just started with using Lunatask to help keep myself on task, and help me remember a lot of the little things I tend to forget. I’m still learning what the app is fully capable of, but it’s been super helpful to me so far.

It is an end-to-end encrypted, cross-platform, todo list, notebook, habit and mood tracker, and journaling app built with ADHD brains in mind. The creator has also expressed some willingness to open source in the future, but there is no guarantees there.

For what it’s worth, Apex Legends literally runs smoother on my Arch Linux install than my Windows 10 install. It was completely unexpected, but a very welcome discovery.

I find Brave’s dependence on Chromium (and therefore Google) to be troubling. They don’t have the engineering team to keep up with Google as they continue backtracking on the “Don’t Be Evil” motto.

For the same reason, I prefer Brave Search over DuckDuckGo. DDG relies almost entirely on Bing for its results. In comparison, Brave Search has a completely independent search index and does its own web crawling.

Range is an issue, but Bluetooth can reach up-to 100 meters. It depends on a lot of factors.

If you have a lot of people with it installed, I believe it also has the ability to bounce from one device to another (like Briar).

Out of curiosity, if you’re on a Pixel, why not choose GrapheneOS?

So I tend to agree with the PrivacyGuides.org Team on this one. I’ll break it down slightly differently though. Brave isn’t BAD per se, but I strongly prefer not using a Chromium based browser unless it’s 100% necessary.

Most private and secure but frustrating to use: Tor Browser

Private and secure, still frustrating for daily use: Mullvad Browser

Able to be private and secure, defaults aren’t perfect. Firefox + uBlock Origin

Private and secure by default, potentially slowly updates and a smaller team might impact security. LibreWolf

Chromium Based Browser with good Security and Privacy, defaults aren’t perfect: Brave

Chromium based browser with good privacy, but potentially slow updates and a smaller team. Ungoogled Chromium + uBlock Origin

Happy to have introduced you! 🙂 Hope you find it as helpful as I have.

One point for Brave, is that they have specifically said they will continue to support Manifest v2 in their browser.

Just a few reasons off the top of my head:

Service disruptions, protest communications, censorship resistance, and emergency service communication in areas without cell service (ocean, wilderness, etc).
