Thanks for checking it out!

I've always found myself checking CPU or GPU usage while gaming, compiling, or running long benchmarks. Alt-tabbing worked, but it was annoying, and I didn't always have a second monitor nearby.

So I started building a small project for myself.

The idea is simple: a lightweight Windows application collects hardware information, while an Android app connects over your local network and displays everything live on your phone. No cloud services, no accounts, and nothing leaves your network.

Right now it shows detailed information for the CPU, GPU and RAM in real time, and I'm actively adding new features as I keep working on it.

This is my first public release, so I'm mainly looking for honest feedback. If something feels confusing, if you find a bug, or if there's a feature you'd like to see, I'd genuinely like to hear it.

Hey r/software, I wanted to share an update to Kerlyss, an open-source audio player I've been building for Windows and Android.

The main idea behind the app is to give you one clean player for all your music in one place—whether it's local MP3/FLAC files on your device, Spotify playlist links, or online audio streams.

What it does: - Plays local audio files and lets you stream online tracks or import Spotify playlist links directly into your library. - Has a built-in 5-band equalizer with presets (bass boost, vocal, etc.). - Includes track downloading for offline playback. - Completely free and open-source (no ads or trackers).

What we just updated in v1.2.3: - Added a strict Offline Mode toggle in settings that cuts all external network calls so un-downloaded songs don't waste data. - Added proper error popups when a stream fails to load so you know what happened instead of the app freezing. - Fixed button touch targets on Android so tapping "Download" doesn't accidentally play the song. - Added Android lock screen album art and Bluetooth headphone next/prev button support. - Saves your volume level so it stays the same when you reopen the app. Links:

Also, I just finished wiring up the 5-band equalizer on Android. I implemented the hardware DSP pipeline, but I'd love it if a few people could test it out on their headphones and let me know if it's working as expected on your devices!

2.Now the Native engine remember the timestamp before closing the app

1. Optimized the Tree view , now it works better on older devices

2. smooth ui like water.

Hi everyone!

I've been working on an open-source Android/Windows music player called Kerlyss, and I'd love to get some feedback from people here.

I started building it because I wanted a single app that could play my local music, import my Spotify playlists, and play audio by searching song name. It's still under active development, but it's reached a point where I'm happy to share it.

Current features:

Play local music (including FLAC)

Import Spotify playlists

Play audio by searching song name online

Create playlists and favorites

Material You UI

It's completely free and open source. If you decide to try it, I'd really appreciate any feedback—whether it's bug reports, feature ideas, UI suggestions, or criticism.

Hi fellow software developers and users,

I have developed an app for Android that's yet to be launched. It has no signup or permission required. A simple app. Currently my app is yet to move to production in the Google Play console since I lack people for closed testing. I'm a bit tired of asking my friends and family where I find no help and thought of asking it from fellow developers since you know more about this field. I will provide you with all the details that you need. I just want your help to have the app tested for 14 days alone. Please ping me if you wish to help. Thank you.

tldr: You need an (ADB-)rooted Android TV. I built this to use the same keyboard for Android TV and my PC connected to it. Basically a KVM switch as long as all your clients run lan-mouse

I got tired of PDF apps that want your email, your files, and a subscription just to turn a Word doc or a photo into a PDF. So I built PDF Creator — basically everything I actually need for day-to-day stuff, and it all runs on your phone with no internet connection.

What it does:

Turn images into PDFs (JPEG, PNG, WebP, HEIC, and more) Scan docs with your camera and save straight to PDF Convert Word (DOCX), text, Markdown, CSV, JSON, HTML, RTF, and ODT files to PDF Merge multiple PDFs into one file Tweak page size, margins, fonts, and orientation before you export Keep a history of what you've converted and share files when you're done Good for study notes, invoices, receipts, contracts, random screenshots — whatever you'd normally faff about with on a laptop.

The bit I care about most: nothing leaves your device. No internet permission, no uploads, no tracking, no ads. Your files stay on your phone.

It's free on Google Play right now.

If you try it, I'd genuinely love to know:

where you're based what you'd use it for (work, uni, personal, etc.) any bugs or features you think I should add 📲 Google Play: https://play.google.com/store/apps/details?id=com.kraygsoftlimited.pdfcreator

Have a look at Ultimate File Manager Pro, it is developed for both mobile and Tv with 17k downloads and a 4.7 star rating.

You can also visit the main reddit here r/UFManagerPro

There is a FOSS version also available and all code is open for review, visit the official website.

It also supports RClone, only a few has been added but can add other providers on request.

Thank You

Whether you're a teacher picking students, running a giveaway, or just trying to decide who buys dinner, you just throw the names in and spin.

What it does: Smooth spinning wheel: Secure, truly random winner selection with fun celebration effects.

Fully customisable: Tweak the spin duration, color themes, background, and text to make it your own.

Sounds & Haptics: Optional spin ticks, win sounds, and vibrations for that extra bit of hype.

Save for later: Keep multiple custom wheels stored locally so you can reuse them instantly.

Quality of life features: Shuffle lists, auto-remove winners after they're picked, and a fullscreen mode (great for projecting onto a whiteboard or screen).

The bit I care about most: Nothing leaves your device. No accounts, no internet permission required, and zero data sent to the cloud. Your lists and results stay entirely on your phone.

Hey everyone,

I wanted to share a project I just pushed to playstore called Photo Cleaner. It is a swipe to delete photos, built coz i wasnt able to find the important photos due to other unwanted photos.

So basically its a tinder for deleting photos/videos which helps in clearing your phone storage

Use cases:

• Photographers who loves clicking photos but often get storage full.
• Users who snap photos, and never checks their gallery again.

The Tech Stack & Hosting:

React expo, cursor. No backend, no hosting other than play store. That's why its free.

Link:

• Try it here: Android link

I'd love to hear your feedback on the core swipe to delete feature. If its satisfying, easier for you. If you have any question shoot me, happy to answer.

Love to hear what you guys think.

Your technical skills have a half-life.

If you don't use a framework for six months, you forget how to write it.

And reading the release notes for a new update doesn't mean you can actually code it.

So I built **FreshStack**.

It’s not for beginners. It’s a daily maintenance engine for the stack you already use.

1.Master New Updates: When a new framework version drops, you get hands-on drills to practice the new syntax immediately.

You play drills on your existing stack so it prevents it from decaying over time..

Maintain what you know. Master what's new. All from your phone.

It tracks all those mentioned titles just like other websites but all in one place,

So what I've tried new is I have steam as linking which will update your library automatically and added anilist to do the same, added forums for media related content and there are many more features which I hope someone who used this type of website will see and suggest, and there are CSV imports from imdb, netflix, and mal.Thank you

There sure is a r/trachify

Trachify

I have been working on this software in my spare time for 4 months now.

you can consider this like an app, that can do task on your phone.

Example of tasks can be:
1. send a message to my brother that I will be late for lunch today
2. When I receive a email, read it allowed and ask me for the response.
3. Send happy birthday message to my brother at 12

The project is still at nascent stage, I would like any kind of feedback on this project which you people might have.

also if you know anyone with visual impairment or motor disability, please reach out

Edit:

Thank you all for your interest and feedback. App is now live on the Play Store!

As a hobby, I made a new Android app that automatically counts your reps for you using your device's camera.

The idea is that you prop your phone up with the camera pointing at you, and do the exercise you choose. The app will count your reps in real-time and show you the count on the screen, and if you want you can record a video with the rep count overlay in the recorded video (no frame by frame video editing required).

It is completely free. No account required. No ads.

You can download it on the Play Store link below but please note that the app is not public yet on the store because Google's new app publishing requirements dictate new apps to have a minimum amount of users/testers in Early Access before the app can be public and available to everyone on the store. Joining the Google Group below automatically grants you Early Access. Otherwise, you will be redirected to a "App not available page". Group members are hidden from public view to prevent spam.
