PDS Technology
Our apps
Serious, self-contained iOS apps built in the UK. Each one takes something that normally needs other computers, a data-science workstation, a cupboard full of board games, a case of poker chips, a book of hidden 3D pictures, a desk full of MIDI hardware, a synthesis course, a developer’s toolbox or a WiFi surveyor’s kit, and fits it onto the device already in your hand.
Everything on device
Each app does all its work on your iPhone or iPad. Nothing is uploaded, and everything keeps working with no internet at all.
No accounts, no tracking
Nothing to sign up for and no analytics watching you. What happens on your device stays there.
No subscriptions
We do not rent software. Where an app has paid features, one purchase unlocks them forever.
Quick ML
A complete data-science studio in your pocket.
Import real datasets, explore and clean them properly, train machine-learning models, and make predictions: the whole workflow, entirely on device. A million-row CSV is fine. Built for data scientists and students of data science who don’t always have a laptop with Python to hand.


Group Games
This device is the table.
70 family games on one screen in the middle of the table: boards, arcade duels, cards, dice and learning games. For games with secret hands, everyone joins from their own phone’s browser with nothing to install. Tournaments, leaderboards and family-friendly controls included; internet not required, ever. Free to download, with seven games free to keep and one purchase for the rest.
Group Poker
Home poker night, no chips.
One iPad or iPhone is the table; everybody else’s phone is their hand, joined from a QR code with nothing to install. Four variants, tournaments and cash games, and up to 30 players across three tables, all over your own Wi-Fi with no internet needed. Play-money chips only, paid once, with no in-app purchases. The grown-up sibling of Group Games.


Stereogram Studio
Hidden 3D pictures, made on your iPad.
The pictures made famous by the Magic Eye books, made by you. Start from a shape, a 3D model, a depth map, a LiDAR photo, a drawing or a line of text, pick the pattern it hides in, and draw it at print resolution. Decode any stereogram back to its hidden relief, animate the shape into video, build seamless patterns and print a book. Making and decoding are free; one purchase unlocks exports.
Maxy MIDI
Build your own MIDI controller.
Drop knobs, faders, pads, keyboards, launch grids, mixer strips and DJ controls onto a page, set what each one sends, and play your DAW or synthesiser over Wi-Fi, Bluetooth or USB. Mackie Control and HUI are built in, Ableton Live, Logic Pro and Reason are wired already, and there are sixty six layouts to start from. Free with a one-time Pro purchase that takes the limits off.

Learn Synths
Learn synthesis by playing it.
Forty-nine lessons on one synthesiser, built up a control at a time. Lesson 1 is four waveforms and a scope; lesson 49 is a full instrument with sequencing, effects, sampling and MIDI, and every sound is synthesised as you touch it. Seven genre studies, tours of Sylenth1 and Serum 2, eleven sound-design challenges and three AUv3 plug-ins. The first three lessons are free; one purchase unlocks the rest.

Dev Army Knife
101 developer tools in your pocket.
A Swiss army knife for developers: a code editor, JSON, regex and diff, SSH, SFTP, an API tester, a mock server, a Git client, image and icon tools, network diagnostics and a shelf of reference sheets, in one app. Every tool runs on the device, and every output has a Send to menu that carries it into the next tool. 43 tools are free and stay free; one purchase, Pro, unlocks all 101, with no subscription.

WiFi Plan
See where your WiFi is strong, and where it isn’t.
Scan your home with LiDAR or draw it with a finger, then walk round measuring the real speeds you get. WiFi Plan turns the points into a heat map of every room, works out which router or extender each measurement came through, and shows where an extender would help before you buy one. Free to try with one project; one purchase, Pro, takes the limits off, with no subscription.
