Experimental Android apps,
built for learning and fun
ExperimentApps is a small hobby studio for experimenting with app ideas, programming techniques, and AI-assisted development. We build experimental Android apps — and now also Windows applications — to explore what’s possible, learn as we go, and share what we discover. Our apps have no accounts, no ads, and no tracking. They simply do their job.
Our apps
Keystroke Sender
Turn your Android device into a USB or Bluetooth keyboard and mouse that can "type" scripted keystrokes into a connected PC — no software needed on the PC.
Pocket NAS
Turn your Android phone into a small, secure network drive. Share a USB drive or internal storage with your computers over Wi-Fi, a USB cable or a private Wi-Fi.
FileDeck
A file explorer for your phone, tablet or Chromebook that also opens your NAS, SFTP, FTP, WebDAV and Windows shares. Copy files between any two places.
Media Viewer
A private, offline photo and video viewer. Browse your folders as collections, swipe and zoom — with no internet access and no permissions needed.
NetScope
A local network analyzer: find every device on your Wi-Fi, then ping, trace, scan ports, look up DNS and wake computers — without any cloud service.
SFTP Studio
An SFTP, FTP and SSH server and client in one app. Share folders from your phone with any computer, or connect to your web host or NAS.
SyncDeck
Folder sync and backup to a USB drive, a NAS or another computer — on a schedule, in the background, with safety checks built in.
Tag Actions
Link any NFC tag to one or more actions. Scan the tag and its actions run — Bluetooth, volume, Do Not Disturb, smart home and more — even when the app is closed.
LED Ticker
Turn your phone into a scrolling LED sign. Tap phones together to build one long display that scrolls from screen to screen.
Tether
Remote control for your computers: see and operate a Windows, macOS or Linux desktop over VNC, or open a terminal or PowerShell over SSH.
Offline Recorder
Record in the background, turn speech into text and make shorter, cleaner copies — entirely on your phone, without internet access.
NetWarden
See which apps connect to what, and block addresses, domains, URLs or whole apps. A firewall that runs as a local VPN on your own phone.
Off
No screens, just an icon: tap it to turn off and lock your phone in one go, so the next unlock asks for your PIN code.
Our games
All our games work fully offline and request no permissions at all.
Make Ten
An offline number puzzle: swipe through touching numbers that add up to exactly 10. Long chains score big. Two modes and four difficulty levels.
Hex Marbles
An offline, turn-based strategy game. Claim hexagonal tiles with marbles, grow them, and push the computer players off the board.
2048
Slide, merge and reach the big tile. Four board sizes, hints, unlimited undo and a danger indicator that looks ahead for you.
Number Match
Cross out pairs of equal numbers or numbers that add up to 10, and clear the board. Four difficulty levels and hints that never lead into a dead end.
Sudoku
The classic number puzzle with four difficulty levels, quick pen and pencil input, and a dot that tells you whether every digit is still correct.
Hitori
Shade the duplicate numbers and keep the rest connected. A Japanese logic puzzle with hints that explain why.
Nonogram
Fill the grid by the numbers and reveal a picture. 85 hand-drawn puzzles in four sizes, with a gallery of everything you have solved.
Mahjong
The classic tile-matching game with five layouts. Remove pairs of free tiles — a light warns you the moment you play into a dead end.
Solitaire
The classic Klondike card game with draw 1 or draw 3. A built-in solver tells you whether the game can still be won.
Spider Solitaire
The two-deck patience game with 1, 2 or 4 suits. Every deal is checked to be winnable before it is dealt.
FreeCell
All cards face up, with 2 to 4 free cells. The numbered deals match classic Windows FreeCell, so game #1 is the one you remember.
TriPeaks
Clear three peaks of cards by playing one higher or one lower. Build long streaks without drawing for the biggest scores.
More coming
This is where our next experiment will appear. We build in our spare time, so new apps arrive when they are ready.
Our Windows applications
Programs for your PC, delivered as a zip file: unpack and run, no installer needed.
What we stand for
- Privacy first. Our apps do not collect usage data or personal information, and never send anything to us.
- No cookies, no trackers — on this website or in our apps.
- Free to use. We never ask for money or in-app purchases. (If you use a cloud AI in AI OS Controller, that provider may charge for its API.)
- Transparent permissions. Every app page lists exactly which permissions the app asks for, and why.
- Experimental by nature. These are hobby projects shared for learning and fun.
