Music Invaders 1.0

Crafted by John Penner, April 2016

Music Invaders is a sheet music trainer that helps you learn how to read sheet music. Musicians and students can brush up on their reading abilities, and learn to read music.

In Music Invaders, you have ten bases to protect - take care of them by playing the right notes as they come flying across the staff. Unlike other note trainers, a hovering alien will actually zap your bases if you dont play the right note. Play harder (on a MIDI device), and the notes shoot faster.

Set your iPad on a music stand and learn to play. Set the complexity of play — Single notes, Thirds, and Triads. Beginners can limit the range of notes to the Treble or Bass clef.

Tap the treble or bass clef to change keys. Blue lights indicate valid notes within a scale. With Auto-Rollover enabled, as you progress, the scale will advance through the circle of fifths every 10k. A small graph lets you track your progress as you work your way through every scale.

For the best experience, we recommend using Music Invaders with a MIDI keyboard. Notes played via MIDI are velocity sensitive and fire faster as you play harder.

NEX4 1.0

Crafted by John Roland Penner, May 2015

NEX4 is a simple and fun app for the iPad — Connect four of your pieces in a row — you get 100 points, and the pieces vapourize causing the pieces above it to collapse — creating unpredictable new combinations for you to maneuver. If you manage to connect more than four in a row — you are in for a Multi Collapse. The game ends when the board is filled, and the player who gained the most points is the winner.

Simple to play with endless variety. Play NEX4 Today!

Chess Meister 1.0

Crafted by John Roland Penner, November 2014

Chess Meister is an App for the iPad that provides a simple and beautiful interface where nothing comes between you and playing chess. Share the board with another player, and the pieces turn to face the player whose turn it is. Few controls, endless possibilities. Tap the blue button, and Chess Meister's peaBrain engine moves for you.

Give the peaBrain a hard move — it'll think longer and harder. If you make a bad move, be prepared for the peabrain's rapid response. Use the unlimited undo-redo; or swipe left and right for the start and end of the game. Step through moves rapidly. Examine possibilities, develop your game and learn the names of the opening books.

Chess Meister is a challenge for new chess players and a companion for two people who need to share a chess board — inlaid with Morpho butterfly squares and Brazilian hardwood — a classic rendered in a modern parallax interface.
