Discipline without excuses.
Most habit trackers are built to make you feel good. Constants is built to make you dangerous. No streak padding. No forgiveness. Just a strict system and an AI that refuses to let you lie to yourself.
I didn't build this for you. I built it to save myself.
My name is Kacper. I'm 21, I'm a uni student, and I still live with my parents. For years, I was completely lost. I'd watch hours of self-improvement videos on YouTube, download every new productivity app, and convince myself I was making progress. I wasn't.
Being an INTJ, I over-analyzed everything but took zero real action. I was trapped in a cycle of procrastination, and none of the software out there actually helped. They were too soft. They just gave me cheap dopamine hits for ticking a box. It felt fake.
Quite recently, I finally got so frustrated with my own lack of direction that I decided to just build my own solution. I had absolutely zero coding experience. But over 7 days, I grinded it out and built this exact web app.
I didn't build Constants to sell it. I built it because I desperately needed a system that wouldn't coddle me. A system that actually punishes me when I'm being lazy and forces me to stay consistent.
I use it every single day now, and it has genuinely changed my life. If you're stuck in that same loop of watching videos but doing nothing, this might be exactly what you need to break out of it.
