Show HN: Joonote – A note-taking app on your lock screen and notification panel

https://joonote.com/
19•kilgarenone•5h ago
I finally built this app after many years of being sick of unlocking my phone every goddamn time I need to take or view my notes. It particularly sucks when I'm doing my grocery and going down the list.

I started building last year June. This is a native app written in Kotlin. And since I'm a 100% Web dev guy, I gotta say this wouldn't have been possible without this AI to assist me. So this isn't "vibe-coded". I simply used the chat interface in Gemini website, manually copy paste codes to build and integrate every single thing in the app! I used gemini to build it just because I was piggybacking on my last company's enterprise subscription. I personally didn't subscribe to any AI (and still don't cuz the free quota seems enough for me :)

So I certainly have learnt alot about Android development, architecture patterns, Kotlin syntax, and obeying Google's whims. Can't say I love it all, but for the sake of this app, I will :)

Anyway, I finally have the app I wish existed, and I'm using it everyday. It not only does the main thing I needed it to do, but there's also all this stuff:

- Make your notes private if you don't want to show them on lock screen. - Create check/to-do lists. - Set one time or recurring reminders. - Full-text search your notes in the app. - Speech-to-text. - Organize your notes with custom or color labels. - Pin the app as a widget on your home screen. - You can auto backup and restore your notes on new install or Android device. - Works offline. - And no funny business happening in the background https://joonote.com/privacy

It's 30-day trial, then a one-time $9.99 to go Pro forever.

I would love you all to check it out, FWIW.

Ok thanks!

First they controlled Hollywood.

Then they controlled all of Politics.

Then they controlled when we went to war.

Now you want them to control your notes???

/s but “Joo” is filterspeak for “Jews”. Sounds antisemitic as fuck.

mireofthedeep•1h ago
Joo is also Finnish for "yes" or "yep", name sounds like "yes-note".
Vaslo•1h ago
You are totally right but the name may still be an unfortunate choice for native English speakers
__turbobrew__•1h ago
That is a poor choice of naming. Sounds like JewNote.
--_--•1h ago
I was going to say that too. Perhaps it came from a non-native English speaker. Please change it.

I like the idea, if it's actually safe and you can't use this to get into your phone through some tricky means like a buffer overrun.

rjtavares•51m ago
As a non native speaker, it never crossed my mind and I was quite confused at the first comments...
ashwinnair99•1h ago
Simple idea, right surface. Lock screen is the most underused real estate on a phone. Curious how you handle the note limit before it gets cluttered.
politelemon•1h ago
Great demo video as well, I appreciated that it didn't waste time. I'll echo the comments here though, the name doesn't sit well with some audiences.
comrade1234•59m ago
I don't think you should name it that...
lucasay•39m ago
Cool idea, lock screen notes actually solve a real annoyance. But yeah, you might want to rethink the name—it’s likely to turn people off before they even try it.

I believe the politically correct phrasing would be Jooishnote.
