Clef vs Tenuto: Honest Comparison

Choose Tenuto if you want a one-time $4.99 purchase with broad, customizable theory and ear-training exercises that you set up yourself. Choose Clef if you are a pianist who wants the app to plan each session: FSRS spaced repetition brings back the notes, intervals and keys you miss, sessions take about three minutes, MIDI keyboards work, and treble and bass drills are free.

Where Tenuto is stronger
Breadth for the price. For $4.99 once, Tenuto gives you ear training, construction exercises and calculators that Clef does not have, with fine control over every exercise. For a theory student who knows what to practise, that is excellent value.
Where Clef is stronger
Deciding what to practise. Tenuto asks you to pick and configure each exercise; Clef tracks every answer and schedules the weak items back automatically, so three minutes a day goes where it matters. Clef is also built for the piano itself, with MIDI input and technique drills for scales, arpeggios and hand coordination.
Can you use both?
Yes. Tenuto is a good companion for ear training, which Clef does not cover. Clef handles the daily, scheduled reading and keyboard work.
