Feature Comparison

Polym

Medium-form Content on Foundational Knowledge

Polym offers medium-form courses that delve into essential subjects, providing relevant information that spans various professional fields. This approach ensures learners can engage deeply with the material while also catering to those aspiring to be polymaths.

Retrieval Practice

The app employs dynamic retrieval practice techniques that mimic audio flashcards, allowing users to actively engage with the material. Research shows that active learning enhances retention and recall, making it a core feature of the Polym experience.

Spaced Repetition

Polym utilizes spaced repetition to prompt users to review and practice key subjects at strategic intervals. This method strengthens memory retention by ensuring that users revisit material over time, maximizing long-term understanding and recall.

Interleaving

Polym's interleaving strategy mixes related topics and skills during study sessions. This approach helps users to make connections between different subjects and enhances their ability to apply knowledge in varied contexts, thereby enriching the learning experience.

The Ultimate Piano

Real-Time Chord Detection & Chord Explorer

As you play on your connected MIDI keyboard or computer keys, The Ultimate Piano instantly analyzes and displays the names of the chords you are playing. This immediate feedback is invaluable for understanding harmonic progressions during improvisation or song learning. The integrated Chord Explorer allows you to delve deeper into music theory, visualizing chord structures, inversions, and relationships on the keyboard to build a solid theoretical foundation.

Interactive Scale Trainer & Learning Modes

Move beyond rote memorization with the interactive Scale Trainer. Choose from 14 different scale types (like Major, Minor, Blues, or Pentatonic) in any key, and the tool will visually highlight the correct notes on the keyboard. It can even play the scale for you. This feature provides detailed performance analysis, helping you practice scales accurately and consistently, which is essential for technique and soloing.

Integrated Audio & YouTube Player

Practice along with your own music or any online tutorial seamlessly. Load MP3 files directly into the Audio Player, which can automatically analyze BPM and key. For online resources, paste any YouTube URL into the YouTube Player. You can slow down playback, set precise A-B loop points to repeat tricky sections, and save markers to jump to specific moments, making it an ideal tool for learning songs by ear.

MIDI File Support with Falling Notes Visualization

Upload any standard MIDI file to practice with a visual guide. The notes from the file will light up on the on-screen keyboard as they play, creating a falling-notes or "piano roll" style display. You have full control to slow down the tempo, pause, step through note-by-note, or loop difficult passages. This transforms any MIDI file into an interactive sheet music and practice aid.
