Open source cars…

An open source and private chat app that everybody wants to use

NFC payments app.

I know it's an unobtainable dream, but a banking app for every bank on any platform.

Software that burns down the server of any website that asks for data they don't actually need.

health smartwatch app, with sleep n all features in some opensource format that could use any other app data... utopia, i know

Not sure if this already exists in some form, but I want something that always records where I've been. I am a very forgetful person and the Google maps timeline feature has been very helpful more than a handful of times. Unfortunately, it means that Google knows exactly where I've been also...

I just want to be able to check where I was the afternoon of a random Tuesday three years ago!

A browser addon that utterly floods advertisers and trackers with dummy data. A single person using it is easy to single out. A thousand start to eat into the profits. 100k should make them go offline (DDoS'ed) with an interesting frequency.

Do services count? Because in that case, ride-hailing. A replacement for services like Uber and Lyft.

Signal to work for SMS again 🙄🙄🙄

I just want GoG but for movies

Something that produces a wealth of plausible web traffic on my connection and browser that woefully misleads anyone monitoring it as to what I actually am browsing. Rather than hiding my traffic or ensuring some hyper level of encryption I simply want to use maybe an LLM or something to create such a close facimilie to "normal" online traffic that my online fingerprint becomes useless as sub 5% of my traffic is actually real.

Essentially I want privacy through drowning out everything with noise. It seems like the harder the to unwind in the end if done in a clever way. That plus some basic security protections and I will feel fairly secure.

Not sure if this counts, but a simple FOSS BIOS/UEFI option that could be installed on most desktops and laptops. The current options (Libreboot, coreboot) are very limited in compatible hardware.

A ridiculously user-friendly encrypted email default.

A version of WhatsApp that doesn't require full access to all your contacts to work properly. I have about 10 people I need to Whatapp with - I just want to add those people. Meta doesn't need to know my Doctor's phone number.

Me getting ideas from this thread

I would like a browser addon that drops poisoned data when surfing the web. Instead of trying to restrict how much of my data gets collected, spread useless data across their sites.

Android auto

an anonymous front-end for viewing Facebook pages á la Nitter or Invidious.

Wallet app that I can tap using NFC so I don't have to carry my wallet around and lose it again. I really miss Google Pay after switching to GrapheneOS

An open source app for those bag, key, and wallet trackers. Maybe I just haven't been able to find one

A local personal assistant that isn't just focused on media consumption or purchasing. I want to ask about my most efficient route or ideal presents for my partner or a medical condition without it being data mined.

I made a weather app for android because most of them wanted my data.

Ever since Signal removed SMS capability I've really hoped to see SMS added to the FOSS fork Molly.

Not sure if this exists at all, privacy friendly or not, but it is something where privacy would be extremely important.

I would love to have some sort of application that allows the mapping of atomic (as in minimal) political statements and their logical relationships (e.g. if this is true then this other statement can't also be true) and evidence from media for their truth or falsehood. Probably also some sort of glossary of precise word definitions and which statement uses which of the definitions. This part should probably be done publicly and shared with other users apart from maybe a mechanism to obscure who added which information but this next part can not be public but lots of people would want the information. You should be able to mark each of those statements as something you agree with or not and then explore the implications of your opinions.

I feel something like that would be nice to replace the constant repetition of the same arguments on the same issues, especially if one could publicly link to individual statements from anywhere on the internet.

Good Todolist app like MS Todo, but better and privacy friendly and open source

Search engine like yacy. Open scource and p2p.

For Signal to actually show notifications, I don't understand how this bug still exists after years of it being known.

Havent tried every app but If I had to think of some:

• an offline foss calendar that can import ics files (simple calendar is the only option soon fossify)
• an app that can display Checksums for files
• a dark privacy overlay for phones that can't use privacy screen protectors, like newer gen pixels

Edit: Second an offline fitness tracker where a person can manually input info. Been using an ods file for a couple of years but its a pain to use collabora on android

• A good Invidious player with locally stored datas.
• AntennaPod fork with improved local music management (tags).
• A dedicated good PeerTube app.

They are dozens of great, free software applications developed… the problem is getting the masses to use these applications.
