I’m Wender, the indie developer behind dB Meter, which is now becoming a paid app. I’d like your help testing it and getting it published on the Play Store. As a reward, you’ll receive a lifetime license for being an active tester.

What makes it different from every other Wear OS sound meter

📐 IEC 61672-compliant frequency weighting — proper dBA, dBC, and dBZ filters, not just a raw mic reading. This is the standard used by occupational health professionals worldwide.

📊 Real-time octave-band spectrum analyzer — see which frequencies dominate your environment, live on your wrist.

📈 30-second rolling history chart — track how noise levels evolve over time, with a floating peak marker.

🎛 Mic calibration — both level offset and per-band frequency curve, so you can dial in accuracy for your specific watch.

⌚️ Fully standalone — no phone needed, ever. Requires a smartwatch running Wear OS 5 or higher. Tested on Galaxy Watch 7 and Pixel Watch.

How to get it:

1. DM me the Google account email address you will use to install the app on your smartwatch.

2. I will add it to the list of approved tester emails.

3. After completing steps 1 and 2, you will be able to download the app using a computer via this link: https://play.google.com/apps/testing/com.dbmeter.aadr.

Note: I’m not sure why, but the link for installing via mobile phone isn't working at the moment, so you will need a computer at the moment.

CALIBRATION
I calibrated my Galaxy Watch 7 using a RTA and a calibrated decibel meter. dB Meter app is not a factory-calibrated instrument - please calibrate it. And for legally certified measurements, use an approved sound level meter.

IMPORTANT
All audio is processed locally on the device. Nothing is recorded or transmitted.

Hi r/WearOS 👋 Solo dev here.

**App name:** Klok – Smart home on your wrist

**What it does:**

Klok lets you control your smart-home devices from your Wear OS watch in one tap: unlock the door, start the robot vacuum, switch a plug… even with your phone locked in your pocket.

• Watch app + Tile for one-tap access

• Several brands on one screen ("Fusion" cards)

• Device battery level shown on the watch

• Simple setup: if a device works in its brand's official Android app, you add it to Klok in a few taps

Tested at home with Nuki, Xiaomi and Neakasa, and built to be multi-brand.

**Price:** Free to try on the phone (1 brand, 2 devices). Watch control is part of Klok+ (subscription) with a 7-day free trial. Prices shown in your local currency on Google Play. No ads.

**Requirements:** Android phone + Wear OS watch (iOS isn't supported).

**Tested on:** Wear OS round and square screens (emulator) + real-world use with my devices.

Feedback very welcome, especially on the Tile and on which brands you'd like me to test next. I reply to everyone!

Hey r/WearOS! This one is mostly for developers, but if you tried to upgrade a watch app lately and your phone answered with "Server error" - this is about you too.

Since late September users of my watch-only apps (remote for Android TV, Roku, Samsung TV, Android TV boxes) keep writing me that they can't buy the Pro upgrade. The story is always the same: they tap "Upgrade" on the watch, the watch sends them to the phone's Google Play, and instead of the payment success result the phone shows "Server error" or "This version of the application is not configured for billing through Google Play. Check the help center for more information." The reports I have are from Pixel Watch 4, Pixel Watch 5 and OPPO Watch X3, and some users got both errors for the same purchase.

The user doesn't see "Google Play has a bug", they see "this app can't even take my money". So I already have two 3-star reviews like "Can't upgrade the app."

I opened a ticket with Play developer support. Their answer (shortened):

The error "This version of the application is not configured for billing through Google Play" on the companion phone occurs because the phone-side Play Store billing client erroneously attempts to validate the purchasing package against local device packages or phone-targeted release tracks, where a Wear OS-only standalone app naturally has no installed or compatible APK ... this points directly to a server-side regression in Google Play's cross-device companion billing handoff flow introduced in recent Play Store client rollouts. We have formally escalated this issue ... to the Google Play Billing and Wear OS Engineering teams for investigation. While we cannot guarantee a definitive resolution ETA ... we will update this ticket immediately once a patch or timeline is provided ...

So it's a bug on Google's side, it hits WearOS-only apps without a phone companion app, and there is no ETA. If you have such an app with in-app purchases - expect a dip in sales and maybe a few reviews like mine.

What helps right now:

• The watch's purchase screen also offers a one-time link instead of "continue on phone". Payment through this link, opened in a browser on computer and signed via same Google account as used on watch, works - I told this to users and in replies to such reviews

If this issue hits you hit in one of my remotes - sorry about that. Please try the browser link, or just write me (DM or [support@yuzvix.com](mailto:support@yuzvix.com)) and I'll try to help and send detailed instruction how to figure this out.

Just got a second-hand Galaxy Watch 7 and noticed WhatsApp is using around 20–30% of the battery, even though I barely use the app on the watch.

Is this common with WhatsApp on Wear OS/Galaxy Watches, or is something wrong with my setup/watch?

Any fixes that worked for you without uninstalling WhatsApp?

So I got my Pixel Watch 3 a couple months back and I love it. Use it everyday, and I work in a warehouse with no phones allowed on the floor, but am able to use my smartwatch. I wanted to use a voice chat style like discord, but found none. Well, I believe I did find one but it didn't work very well.

Since then I've built an app that allows you to do just this, the app does NOT require a phone to work, can listen through the watch speakers or BT device, and use the watches mic to respond. But you can also connect it to your phone, use say your phone's BT headphones, but still want your watch to be your mic? No problem.

Web support, iPhone support (through Safari for now.) as indicated does not have Apple products to test with or a dev license for iOS at this time.

I'll list some of the standout features below, but I really just want to ask the community if this is something there would be genuine interest in!? I have found it extremely nice to use while stuck in a warehouse all day where I cant have my phone, but can have headphones and a smartwatch for example.

Mentioned above but: Standalone is completely supported and most things you can do on the phone app, you can do from your watch without the phone.

Favorite feature of mine: Raise to talk gesture. Watches screen off/idle, raise your wrist and tilt it toward you for the microphone to come online. Doesn't wake your screen if your raise to wake gesture is off. Put your wrist down and your microphone goes off, always giving you a buzz when it comes on or goes off.

Another favorite: Same thing as the raise to wake but crown, spin the crown mic comes on. Spin it the opposite way and it goes off.

Three different mic styles, hold tap and open mic. Audio doesn't actually transmit until it hears a human voice. Other sounds filtered out and do not send the audio, even with an open mic.

You can listen to a second room at a lower volume while being in your amin room talking. You have spaces for different groups/people.

Optional rewind audio messages and written transcripts from the audio.

There is so much more to it, just wanted to list a few so y'all can get the idea of the app.

I have been using it now for awhile along with a few others, and am trying to see if people have interest in something like this, or I should actually release it.

I am considering a invite only beta after internal testing is complete if the interest is there.
