i found a pair of UTAU Recorders, and are hard-to-find programs, don't counting the fact of bad-archived, so, here's is a list 
VCV Recorder: https://apkcombo.com/es/vcv-recorder/com.utarec.printto.utaurecorder/ (this site is pretty suspicious, but i checked the .APK in virustotal for security and is clear)
Description: is a Old Version of UTAU Recorder, only suporting VCV format, is not recomendable to use it, is very bugged and obsolet, it comes with a VCV Hiragana Reclist, is made by PRINTmov, and got removed of the Playstore years ago, the reason is for outdated API.
UTAU Recorder: https://apkcombo.com/es/vcv-recorder/com.utarec.printto.utaurecorder/
Description;The most famous here, i think what in this forum there are post about this tool, the big problem is the bad quality of the audios, but is definitive better what VCV Recorder, and like VCV, is made by PRINTmov and the app dissapears of the playstore years ago.
Rekuta:https://github.com/atouu/rekuta/releases
Description: Rekuta is probably the best recorder in this moment, avaliable in GitHub, this is a REALLY good recorder, with more funtions, if you wanna record in Android, choose it, and, it continues updating, is a Alpha, and the last up was in Sep of this year.
important: this programs are marked by "dangerous" by google, but is because are made for older versions of Android, ignore that, if you don't trust, always can check in virustotal.
