Holo Apps

Small, focused apps that help people with one thing at a time.

Holo Apps is an independent app studio based in the Netherlands, run by Ruben Dewitte. We design, build and run our own apps for iPhone, iPad, Android and the web.

Pianuance

Sheet music that listens

A practice partner for your digital piano. Connect it over USB or Bluetooth MIDI, open a piece, and the sheet music follows you as you play: every note marked right, wrong, early or late, with the bars that need work picked out for you.

  • Practice, play-along and sight-reading modes
  • Loops, slow practice and a tempo ladder
  • Import MusicXML, or turn PDFs and recordings into scores (Pro)
  • Courses, exam-style tests, ear training and a teacher mode

iPhone, iPad, Android, web, Windows, macOS and Linux

Meet people who understand

A calm place for people living with PSSD (post-SSRI sexual dysfunction) to find friendship, company or a relationship. PSSD can affect sexual function, emotions and thinking, and here nobody has to explain it.

  • Chat, voice notes and calls
  • Built-in safety tools and human moderators
  • Free to use, with an optional Plus membership
