Hey, it's aichi (the guy who created Vulk)
I've always been that skinny guy who couldn't gain weight - no matter what I tried. High metabolism, low appetite, endless gym sessions with no progress... you get the idea.
I tried several apps, but none of them stuck. They were tedious and mostly built for people trying to lose weight, not gain it.
So I built Vulk for two simple reasons:
- To make calorie tracking ridiculously easy
- To let me increase my intake at my own pace
Now I've gained 2.4kg after using Vulk for 4 weeks - something I've never been able to do before.
If you're skinny and struggling to gain weight like I was, Vulk is here to help you finally make progress and feel confident in your own body!
I've never gained weight this fast before! Vulk is super easy to use and has everything I need to stay on track.
