Can you suggest me a vocal microphone application for android? ?

Question

Nothing specific, I just want to hear my voice/echo while I sing, I've looked into a few, but they are glitchy or they don't work at all

Answer 1

Not for android, no.  You don't need a good application, you need a good microphone and recording equipment.

The equipment can be a software package, but you can't use a cheap mic.  A cheap mic is like a cheap cut of meat, because no amount of ketchup or anything else will make it good.  You don't have to spend a fortune on a good mic, just more than 29 bucks.  I've used Peavey mics for decades (I forget the model number), usually right around $100 each brand new, and they've worked really well on stage and in the home studio.

Answer 2

No.. If you want serious audio quality, you need at least moderately decent equipment.

If it must be portable, then look at a Zoom H4N Pro portable recorder.

Those have superb quality and can also work with external dynamic or condenser mics, plus functioning as a PC audio interface so you can use a recorder program or DAW, eg. Audacity or Tracktion.

ps. Always use .wav format to maintain maximum quality. MP3 uses lossy compression and removes detail from audio.
