Comments on Boimero for Android

★★★★☆ Angelica N. · Jul 23, 2026

I'm a BIG fan of this app ^^ I LOVE HOW YOU CAN IMPORT TABLOIDS my only issues are probably how janky it can be to use sometimes and the little amount of ads you can watch for points but aside from that it's really good!! Definitely recommend to people new to utau or anything similar :]

★★★★☆ Person · Jul 14, 2026

This app is really nice and easy to use, especially if you've used UTAU before! I also love how you can import voice banks yourself and is kinda like an American import of paint voice which makes it EVEN EASIER to use since I've used paint voice a lot in the past! Although, there's a lot of ads you have to watch if you want to import a voice bank, sobb(T _ T)

This app would have been good if the lyrics didn't error every time I tried to put them in. At this point l will just buy vocaloid or use utau or some other app because this app sucks. I don't mind ads in aware small creators like this need money, and it's free so that requires ads and people need to stop being greedy when it comes to that. But the issue is actually the errors fix that and this will get more stars. This app is too hard for English speakers.

★☆☆☆☆ Liva Y. · Aug 5, 2026

Do not waste your time or watch ads for this app! The Android version is completely broken and designed to farm ad revenue without giving you the features. I spent hours watching ads to get 10+ points to unlock the "MIDI Batch Import" feature. The app literally gave me a pop-up celebration screen saying "Step 1 Complete! A new feature has been unlocked." But when you go back to the menu, the button is STILL grayed out and locked! The code is broken under the hood.
