Piano Companion is a music theory reference app for songwriters, producers, teachers, and students. Look up any of 1,500+ chords or 10,000+ scales instantly, build progressions, and explore harmony on iOS, Android, and Mac.


Whether you're stuck on a progression, blanking on a scale name, or just exploring — Piano Companion gives you the answer in seconds. Press the keys you know, and it tells you what you're playing.
Search by name or tap the keys you know. Piano Companion identifies what you're playing — even from a MIDI keyboard.
The Chord Progression Builder suggests chords that fit your key. Experiment with patterns, listen back, and find what sounds right.
See notes on the grand staff, fingering for both hands, intervals, degrees, and compatible scales — all in context, not abstract textbook diagrams.
Utilize shared calendar apps to track daily routines and checklists. For Solo Littles (Self-Care Dynamic)
Structure helps quiet the "Big" world anxieties and lets you slip into Little space easier.
But what makes a good rule? How many are too many? And how do you enforce them without breaking the magic of the dynamic?
Rules often focus on health, hygiene, and daily structure to foster a protective environment.
Have a rule you love that wasn’t listed? Share it with your community (safely, without oversharing) and remember: Every dynamic is unique. Your rules only need to work for you and your partner.
In a DDLG (Daddy Dom/Little Girl) relationship, rules are not about punishment or control. They are tools to create a safe, structured environment where the Little can drop the stress of adult life and embrace their regression. Clear guidelines help the Caregiver manage the dynamic while ensuring the Little feels protected, valued, and loved.
