- Purge: find double copies on the phone, and clear only the true extras - never the last copy
- Fix Tags: check the songs in any folder and fix their tags, finding songs by how they sound, by their tags, or by file name

For Linux
Linux builds are on the CashDublo list.
No Linux builds are out yet. The CashDublo apps reach Linux one by one as their builds are made - the first Linux version arrives when its build exists.
How updates work
App updates come from the CashDublo updates shelf - the public cashdublo-updates repo on GitHub.
Updates travel as small patches, not whole new apps: your app saves your settings, builds the new version on your phone, checks it, and only then installs it. If anything does not check out, the update stops safely and your app stays as it was.
Tools I Build With
Phone apps in React Native and TypeScript with Expo. Desktop tools in Python. Every line of code kept on GitHub.
And these are my own build tools - the programs and scripts I made to build the apps with:
GitHub HQ
The home screen for your GitHub repos: every repo with its version, its build scripts and its newest finished build - pull, clone and build from one place.
Build Manager
Builds every CashDublo app from one place: pick an app or build them all, watch the run live, and see what got built - from real build records, never guesses.
Rebuild-All
Keeps every CashDublo repo safe: one small backup file holds the whole set, and the rebuild brings every repo back with only the program and the backup - no GitHub, no sign-in, no internet.
Script-Run
Lists your build scripts in one window, each with a plain line on what it does, and runs the one you pick.
App Translator
Turns the CashDublo apps into other languages - Khmer, Lao and Thai first: one AI translates each line, a second AI checks it by translating it back, and only lines that pass are shipped.
CashDublo Coder
A coding helper that runs on your own computer: ask the AI that lives on your machine, browse your GitHub repos, and jump to the docs and forums that help you build.
Change App Icons
Swap an app's icon on GitHub, with a backup saved first so you can undo it - then it reads the icon back to prove the change took.
Build Scripts
The script family that builds and installs the apps: build one app or every app, send the finished apps to the phone, and keep the scripts themselves up to date from GitHub.
Tools
Small helper programs that run on your own computer.
Change App Icons
Swap an app's icon on GitHub, with a backup saved first so you can undo it. The new picture must be a real PNG or JPEG at the exact same size, and after sending, the program reads the icon back and puts the original back on its own if it does not match.
CashDublo Coder
A coding helper that runs on your own computer: ask the AI (a small model on your own machine, offline after a one-time download), browse your GitHub repos and send a file to it, and jump to the docs and forums that help you build.
Script Installer
Lists your build scripts in one window with a plain line on what each one does, and runs the one you pick - in its own windows, or in the terminal pane inside the app.
GitHub HQ
The home screen for your GitHub repos. It opens on your repos - every one of them, with its version, its build scripts and its newest finished build - and can pull, clone and build them from one place.
App Translator
Turns the CashDublo apps into other languages - Khmer, Lao and Thai first. One AI translates each line and a second AI checks it by translating it back; only lines that pass the check are ever shipped, and the rest are held for review.
Build Manager
Builds every CashDublo app from one place: pick an app or build them all, watch the run live, and see what got built - from real build records, never guesses.
Rebuild-All
Keeps every CashDublo repo safe: one small backup file holds the whole set, and the rebuild brings every repo back with only the program and the backup - no GitHub, no sign-in, no internet.
