Ask HN: What “special” app you are using?

33 pointsyonisto56 comments

Out of curiosity, other than the trivial use cases of smartphone (digital swiss army knife as my FIL calls it) what else are you using it for?

My examples: Sky Map - Point your phone at the sky and it will show you the names of the stars, planets and other celestial objects that you can see.

Sound Meter - uses your built-in microphone to measure sound volume in decibels

Chwazi Finger Chooser - Random Finger Chooser (before anyone asks it helps me to decide random stuff with the kids, like who takes the first turn in any game)

I created a simple browser extension to help me organise my links. It solves a problem I had where there was a middle ground between keeping a tab open to read later and saving something to my bookmarks.

It's under 200 lines of JS, not available on the Webstore and not complicated (or even well-written) at all, but it's a nice feeling to use a little piece of software I wrote that's purely customised to my specific use case(s).

Care to share this? - I’d love to see how you approached this

Happy to DM you the github repo if you'd like!

Why not just post the link to the Github repo here?

I'd rather not share it publicly just yet.

> Sound Meter

Not sure what you're using this for, or which exact app it is, but I use the app put out by the National Institute for Occupational Safety and Health (NIOSH) for this, NIOSH Sound Level Meter[1].

I use Network Ping Lite[2] often to just check if the network I'm on is stable/up.

[2] https://apps.apple.com/us/app/network-ping-lite/id289967115

Just to save the time for others, NIOSH Sound Level Meter is iOS only

Which makes sense, because it's reasonable to test every iPhone model and the microphone qualities. Less so for every possible android device.

DriveDroid- an Android application that allows mounting disc images and causes the phone to appear as an external optical drive or USB flash drive.

I essentially keep an Arch and Windows 10 boot disc on me at all times.

You can also create blank images and it'll act as a flash drive.

Sun Surveyor - shows an overlay on a live camera to see where the sun will be in the sky in summer or winter. Good for gardening and house design.

https://play.google.com/store/apps/details?id=com.ratana.sun...

I use that, too, but for photography. It’s a wonderful app and much easier to handle than the similar and IMHO overhyped PhotoPills.

It’s also on iOS: https://apps.apple.com/app/sun-surveyor-sun-moon/id525176875

Sounds like that would be useful when buying a house

KDE connect - basically apple's handoff but open source and for Linux and windows.

Libretube - YouTube without ads, trackers or an account.

AND Macs :)

And iOS… partially

You should also check out NewPipe Sponsorblock.

I used to use it, but the non stopping crashes since 0.24 made me switch to libretube, and I actually find libretube to have a better UI.

Apart from the social media and streaming stuff:

- Spectroid: A spectrum analyzer to help me identify "that annoying sound I hear" or "what's wrong with the sound in this place?" I'm not good at ignoring sound, but it helps me when I understand something about it, like "oh, that's a 10 khz harmonic" still annoying but slightly less.

- DiggieDog: Gopher client, extremely fast, good for when I'm somewhere with REAL bad Internet.

- Ulysse Speedometer: For driving.. I don't like the ones in cars because they're always somewhat wrong.

- Color Note: Maybe not a special app..

- Podcast Addict: Maybe also not..

How could an app ("Ulysse Speedometer") be better at measuring the vehicle speed?? This seems so wrong!

Off topic but this is a real gripe of mine - analogue speedos that go all the way up to 240 kmph (~150 mph). I am only ever going to do half that speed, so why not just make the dial go to only 120/(80) and give the needle (and me!) twice as much precision!

You probably would better like a digital display that shows a number instead of a needle

Some cars also use unevenly spaced tick marks on an analog dial. Nice in that it gives you the sweep needle and range of scale without overly compressing the range of most interest.

Analog tachometers for race cars do/did the the same thing:

https://www.primusracingparts.com/Racetech-tachometer-0-8-rp...

Maybe limit the dial at 100mph?. Doing 80 on the Interstate near me will get you passed by the impatient. But the real question is why do you need that much precision?

Many gauges are typically designed to work best in the center 50% of their range.

Vehicle speedometers are factory made to display wrong info. I believe they add about 10% to your actual speed.

The reason is error-margin of speedometers, it's about 10% so they err on the side of caution.

Do you have sources for this?

Even if this is not just urban legends, a speed read from GPS data on a phone can only be much worse

https://www.drive.com.au/news/how-accurate-is-your-speedo-20...

Jeep Cherokee appears to be the exception here

My car is using the rotation of the front wheel axle to infer the speed. So it depends on tire diameter (tire type and wear), air pressure, temperature, and the precision of the mechanics involved, and it's generally nonlinear (difference gets larger at higher speeds).

My phone is sampling GPS position at a few Hz, and while the position itself may not be absolutely precise, the relative position from one sample to the next is very good.

Auto Text : Can schedule texts, including reoccurring ones. Also great for reminders in the notification bar. Use it every day.

Joplin : Notes

Macrodroid : mostly to keep my files tidy. Way back in the day of SD cards in phones it helped transfer things over nightly in preparation for my sync job with...

Syncthing : Magical and finicky software

Loop Habit Tracker : Notification pops up, "Did you exercise today?" You answer yes or no and it logs it. I have several questions throughout my day, one of which being how I felt for the day. It's interesting to go back and see which habits improve my day.

Tasks.org (app) : simple to-do app

RaspController : manage local raspberry pis

Wireguard : Selfhost a VPN to "remote" into my home network

YouTube Vanced : Removes YT ads and enables background play. Also restores dislikes and works with Sponsorblock

Privacy.com (app) : Let's you spin up temporary credit card numbers when purchasing things online.

Zone Launcher : shortcut launcher. I swipe from the bottom right of my screen from anywhere on my phone and release over the app I want to launch.

Probably others but I don't even know if these are "special". Just some of my first downloads on a new phone.

Is it still possible to get Youtube Vanced? Last I'd read it got taken down.

It was DMCA'd, yes... but there's still a way. When I last needed to install it the method involved using the wayback machine. If I needed it today I'd start by looking at the subreddit AfterVanced

Day One - A journaling app for iOS, iPad OS, and MacOS that lets you write journal entries, keep multiple journals, sync everything (encrypted) via iCloud, and even lets you print physical copies of your journals if you'd like.

I've been journaling with it for two years now nearly every day and it's 100% wonderful. At the end of each year I order a physical copy of the journal for my personal archive. Highly recommend.

I wrote a simple stopwatch menu bar app called Mini Time Tracker [1] for Mac. I use it to track how much time I do a single thing, e.g. coding. It's like pomodoro in reverse and only stops when you tell it to stop.

- AutoSleep (iOS + watchOS) [0]

I bought it when my Apple watch didn't yet have a sleep tracker and have used it for the last 2 years. Good one! Has helped me understand what works for me and what doesn't. I use the iOS app for analysis.

A sample of my findings :

1. I sleep very well when I have done some hatha yoga exercises + eating early

2. I sleep pretty well when I eat early and eat mostly salads

3. Beer ruins my sleep (no surprise, really!)

4. Cheesy/foods heavy in spices make my sleep bad and my energy levels in the morning low

PrivacyRedirect for iOS (also on Firefox/Mac) auto redirects YouTube to Invidious, Reddit to teddit etc. It doesn’t work perfectly (there are delays or some times it doesn’t redirect for some strange reason) but otherwise it’s fantastic.

Adguard and nextdns for iOS are also useful to somewhat block ads and tracking.

DroidCam. It allows me to use my phone as a Webcam on Linux by streaming over WiFi (or cable). Good stuff

Ableton Note - essentially, make music. fun little passtime.

Ada - like webmd, but more interactive. gives me a rough idea of potential scenarios based on xyz symptoms i'm having.

Cone - not every day use, but identifies colour hex codes using your smartphone camera

Android: Bouncer - powerful permissions management Island - Create a work profile for work apps or apps you want to keep off your main profile

iOS: iVerify - Security related recommendations, guidelines and reminders.

Notin - Creates a simple notification with the text you input. Pro version makes the notifications persist across reboots and unswipable. I use it to make reminders or task lists. I like that is simpler than the alternatives

is there a version for ios?

Foreflight is the best app-for-purpose I've ever used. The smart ruler function is amazing on so many levels and I hate [Google|Apple] Maps every time I use them and want the smart ruler.

Input Director (win64): use the same mouse and keyboard across multiple laptops

AutoHotKey: create custom hotkeys (ie CTRL+RightArrow to skip to the next Spotify song)

Chromacam: add a custom background in MS Teams videocalls

My favorite one is Organic Maps (https://organicmaps.app) - privacy-focused google maps alternative

MyLifeOrganized ; it's the last Windows app I use (on Linux with WINE and Android)

macOS: Fork of Breakaway that instantly mutes audio when the headphone jack is removed. I only use the headphone jack while charging wireless headphones because they fallback to regular wireless ones when unpowered.

Nightcap - iPhone camera app for night photography, star trails, etc.

Star Rover - Star maps

Evie - Ebook text to speech reader - there are many but this one is good.

Camo - helps me to use iPhone as webcam for macOS.
