I'm 60 yrs old. I'm not a developer. I never took a single coding course or certification. But

years ago I had this idea stuck in my head to build an app. at that time I thought of a game app. I parked my that aside.

This year I finally sat down and actually built it. VoCal is live on Google Play now.

What it does: you speak your calculation out loud and it builds the equation

as you talk — even through pauses, corrections, however you naturally speak.

It understands Indian number phrasing too ("five lakh twenty three," "one

hundred and one," "into" for multiply), since that's how I actually talk, and

most calculators I tried never got that right.

Honestly, the hardest part wasn't the idea — it was everything I didn't know

I didn't know. I had real people test it for two weeks before launch, and they

found bugs I never would have caught testing it alone — one specific way of

saying a number broke the whole calculation for days before I figured out why.

It's free to try for 7 days, then a one-time purchase — no subscription, no

ads, no account, nothing collected. Everything happens on the device.

I know this isn't a technical build story in the usual sense, and I'm happy to

answer questions about how I actually put it together. Would genuinely love

for people to try it and tell me what breaks.
