Making a vocal synth song usually takes two pieces: a singing voice tool for the vocal line and a DAW for the backing track, mixing, and export. VOCALOID is still a recognizable name worldwide, but English-speaking creators now often compare it with AI singing voice tools, UTAU-style editors, and mobile options.
This guide looks at practical vocal synth apps for English-speaking users. I focus on tools that make sense outside Japan, have English information available, and can fit into a real music production workflow. If you still need a DAW first, see Best Free DAW Software.

If you are completely new to vocal synths, start by deciding whether you want a polished commercial editor, a free/open-source editor, or an AI singing tool that feels closer to a modern vocal production app.
VOCALOID6

VOCALOID6 is the safest choice if you specifically want the official VOCALOID editor on desktop. It is aimed at users who want to enter notes and lyrics, choose voicebanks, edit expression, and use the result in a larger DAW project.
It is not the cheapest way to experiment, but it makes sense if the word VOCALOID itself matters to your project or you want access to the current official ecosystem.
Mobile VOCALOID Editor

Mobile VOCALOID Editor is the most direct option if you want VOCALOID on an iPhone or iPad. It is better for sketching vocal parts on a touchscreen than for building a full arrangement from scratch.
For English-speaking users, the important point is that the current official page and App Store listing are available in English, and the newer version is designed around a subscription model rather than the older one-time mobile purchase.
VoiSona
VoiSona is a good first stop if you want an AI singing voice tool that can start free and still connect to a DAW. It supports Windows, macOS, iOS, and iPadOS, and the official page explains the workflow in English.
It is especially practical if you want to test vocal synth production before buying a larger desktop editor. For iPad music-making, it also fits naturally beside apps covered in Best iPad Music Production Apps.
ACE Studio
ACE Studio is closer to a modern AI vocal production platform than a traditional VOCALOID editor. It is useful if you want many voice choices, multilingual singing, and a workflow built around generating polished vocal parts from MIDI and lyrics.
Choose it if your priority is realistic AI vocals rather than classic VOCALOID culture. As with any AI voice tool, check the current licensing terms before releasing music commercially.
OpenUtau
OpenUtau is the free and open-source choice for people who like the UTAU community workflow. It runs on Windows, macOS, and Linux, and it can be a good learning path if you want to understand voicebanks and vocal synth editing more deeply.
The trade-off is that it asks more from the user. You may need to install singers, learn resamplers, and spend time with community documentation. If you enjoy tinkering, that flexibility is part of the appeal.
Which one should you choose?
Choose VOCALOID6 if you want the current official desktop VOCALOID environment. Choose Mobile VOCALOID Editor if you specifically want to make VOCALOID parts on iPhone or iPad. Choose VoiSona if you want a free-start AI singing tool that works across desktop and mobile. Choose ACE Studio if realistic AI vocal generation is the priority. Choose OpenUtau if you want a free, community-driven vocal synth editor.
After choosing a vocal tool, you will still need a DAW or editor for the backing track, mix, and final export. If you plan to expand with instruments and effects, Best Free VST Plugins for Beginners is a useful next step.
Summary
For English-speaking creators, the best “Vocaloid app” is not always a single VOCALOID-branded product. VOCALOID6 and Mobile VOCALOID Editor are the direct official choices, while VoiSona, ACE Studio, and OpenUtau cover different parts of today’s vocal synth landscape.
If you want the classic VOCALOID route, start with VOCALOID6 or Mobile VOCALOID Editor. If you want a broader modern workflow, compare VoiSona, ACE Studio, and OpenUtau before spending money on voices or subscriptions.
