Use TheONE Sing App when your immediate goal is to sing with guided accompaniment, lyrics and song-oriented performance tools. Use The ONE Smart Piano App when your goal is structured piano learning, interactive lessons, guided scores, repetition and note feedback. Owners of compatible SING instruments may use both Apps for different sessions; they are not two versions of the same product.

When should you use TheONE Sing App?
Choose it when the voice is the center of the activity and the keyboard supplies an accessible accompaniment. The official pages describe synchronized lyrics, chord-oriented guidance, accompaniment styles, transposition, tempo control and performance recording. Check the current App screen for the exact feature available in your selected song.
This App is not a substitute for a full piano curriculum. It reduces the coordination needed to accompany singing, which is a different task from building independent piano technique.
When is Smart Piano App the better choice?
Choose it when you want a structured learning path, guided songs, short lessons, repetition tools and note-level interaction with a compatible piano. The official App page describes Auto Play, A-B Repeat, light-guided practice and feedback in supported activities.
Its goal is the piano-learning process. If you are trying to build two-hand coordination, read a guided score or repair a short passage, this is the clearer starting point.
Do SING owners need both Apps?
Not for every session. Install the App that matches today’s task. A learner might use Smart Piano App for a focused lesson and open Sing App later to perform a song. Keeping the purposes separate prevents confusion when the song libraries, controls or entitlements differ.
Check compatibility and benefits separately
The current SING product page presents both Apps. Customer-supplied policy for September 2026 lists separate included benefits for Smart Piano App and Sing App on SING and SING Pro, but the duration and activation details should be confirmed on the current order or with support before publication. One successful activation does not prove the other is active.
Frequently asked questions
Are the two Apps interchangeable?
No. Their primary tasks and content experiences differ.
Can you switch between them on the same piano?
Compatible SING owners can use each App for its intended workflow, but follow the current connection instructions and close conflicting sessions if detection is unreliable.
Which App should a complete beginner open first?
Choose Smart Piano App for a structured piano-learning goal. Choose Sing App if the immediate goal is guided singing with accessible accompaniment.
Does one membership unlock both Apps?
Do not assume so. Treat the entitlements separately and verify each account status.
