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!

I just want GoG but for movies

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

Signal to work for SMS again 🙄🙄🙄

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.

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.

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.

A ridiculously user-friendly encrypted email default.

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.

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

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.

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

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

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

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

An open-source, federated, and privacy-protecting alternative to the dominant advertising services. Something that gives the individual web user full control of which ads they see; from which indies, organizations, companies or any other groups. And where they can also filter ads based on clear categories, values, or tags, rather than everything being dictated by algorithms and "relevancy".

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

Search engine like yacy. Open scource and p2p.
