Plenty of music apps assume you already read notation or know your way around a piano roll, which leaves casual players hunting for something gentler. My Singing Monsters Composer takes the opposite approach: it hands you an orchestra of singing creatures and lets you build a song by placing them where you want them. The app comes from Big Blue Bubble Inc, the studio behind the My Singing Monsters series, and it sits in the Music category on Google Play.
It is a paid download at $4.99, with no ads and no in-app purchases. That single price is the whole transaction, which is unusual in a mobile music tool and makes the proposition easy to weigh before you commit.
The pitch is straightforward. Each monster carries its own vocal, percussive or instrumental sound, and you arrange those parts into a piece of music using the built-in editor. The developer describes the editor as powerful and easy to use, and frames the whole thing as a way to pick up musical notation without it feeling like homework.
Building a song out of singing creatures
The heart of the app is the editor. You choose monsters, each with a distinct sound, and place their parts along a timeline to form a composition. Because every creature contributes a specific voice, percussion hit or instrument line, the arranging process doubles as an introduction to how separate parts stack into a whole. The developer bills the editor as both powerful and easy to use, which is the balance any music tool has to strike.
A built-in keyboard is included for entering notes directly. That matters if you have a melody in your head and want to sketch it before you start assigning monsters to it. Between the keyboard and the monster parts, there are two routes into a song: play it yourself or let the creatures carry it.
The monster roster is where the app separates itself from a generic sequencer. Dozens of creatures are available, and the developer notes that Rare monsters bring sounds you will not find on Composer Island in the main game. The Ethereals, a mysterious group from the series, are also available to compose with. For someone who already knows these characters, that is the draw.
Original pieces, recreations and notation practice
You can write something entirely your own or recreate a favorite tune. Both routes use the same tools, so the app works whether you want to imitate or invent. Notation learning is presented as a core benefit rather than an afterthought, which suggests the editor is arranged so that the relationship between written notes and what you hear stays visible as you work.
Skill level is not a barrier in the way it might be with a professional digital audio workstation. People of all skill levels are said to be able to practice songwriting here, and the monster framing keeps the process light. Someone with no musical background can start by placing parts and listening to the result, while someone with more experience can use the keyboard and the fuller monster set to shape something more deliberate.
Recording and sharing are part of the package. You can capture what you have made and pass it to friends, which turns a solitary arranging session into something you can show off. That sharing loop is often what keeps a creative app in use after the first few sessions.
A single price with nothing bolted on
My Singing Monsters Composer costs $4.99 up front. There are no ads and no in-app purchases, so nothing interrupts the editor while you are working and there is no second layer of spending to think about. For a creative tool, that is a meaningful difference: you pay once and the app is what it is.
The trade-off is that you have to decide before you play. With a 3.9 average across more than 6,700 ratings, the reception has been good rather than rapturous, so it is worth reading a few reviews from people who share your musical background before buying. The app has been available since April 2018 and was updated as recently as June 2025, so it is not a project that has been left to gather dust.
Offline sessions and who this fits
The app works offline, so you can compose when you are away from a connection, such as on a flight or on a long drive as a passenger. For a music tool that is a genuinely useful property, since inspiration rarely waits for good Wi-Fi.
The clearest audience is existing My Singing Monsters players. If you already know the monsters and their sounds, the appeal of arranging them yourself is immediate, and the Rare and Ethereal parts are extras you will recognize. The second audience is anyone who wants a gentle introduction to notation and songwriting without the intimidation of a full production suite. The creature cast does the teaching in a way a grid of piano keys does not.
It is rated for Everyone, which fits the tone: colorful characters, simple interactions and no content concerns. That makes it an easy pick for a household where a younger player is showing interest in making music, with the caveat that the $4.99 price applies to whoever downloads it.
A monster orchestra worth conducting
My Singing Monsters Composer is a focused tool rather than a broad one. It does one thing — arranging monster parts into songs — and it does that with a cast of characters that gives the process personality. The absence of ads and in-app purchases keeps the experience clean, and offline support means it works wherever you happen to be.
The strongest case for it is as a first music-making app. The keyboard gives you a direct way in, the monster parts make harmony and rhythm tangible, and the notation angle gives the play a purpose beyond novelty. If you have bounced off more serious music software, this is a friendlier door.
The case against is simply that it is niche. It is built around one franchise's characters, so the appeal depends heavily on whether those creatures mean anything to you. Fans of the series and curious beginners will get the most from it; anyone after a general-purpose music production tool should weigh that narrow focus carefully.
The short verdict
A charming, ad-free monster orchestra that suits series fans and first-time songwriters more than serious producers.
