About SELV.
I'm Max, based in Ukraine.
SELV started with a Google Sheet — 17 habits, each weighted by importance, tracking daily completion percentages. After three months I looked at the data and realized I'd been building a character sheet for my own life. That felt worth making real.
The part of the app I care most about is honesty. Your number is your number, and nothing in SELV exists to soften it. That logic runs through most things I do.
Outside of this: I train regularly and pay attention to nutrition, read a lot about behavioral science and how people make decisions, watch films, spend slow evenings with my partner, and occasionally make something with my hands instead of typing.
What I believe
Honest data over cheerful spin
If you completed 23% of your tasks today, you see 23%. No cheerful message saying you tried. The number is the number. Adults can handle the truth.
You are the character
No pets. No avatars. No narrative layer between you and your data. SELV is a mirror. The character sheet is you — your actual behavior, converted to numbers.
Accumulation, not punishment
XP never resets. Missing a day hurts your completion rate, not your history. You did 45 days. That happened. The 46th day just didn't. Both facts are true.
Low friction, high signal
Logging should take 10 seconds. The dashboard is the reward. Every release cuts steps out of the gap between "I want to log" and "done."
The upside gets shared
If SELV grows, the people who actually used it share in that growth: built bands, logged through hard weeks, sent feedback that changed the product. That group is the Founders Circle. The details are still being designed. The intent is committed.
Who SELV is for
SELV is built for a specific kind of person. You probably recognize yourself in some of these:
- →You've tried habit trackers before and found them either too childish or too punishing
- →You have ADHD or time blindness, and streak-based systems make you feel worse about yourself
- →You love spreadsheets and data but hate how much friction they create
- →You play (or played) RPGs and want your real life to have a character sheet
- →You want to see patterns in your behavior over months, not just today
- →You're data-motivated — you want numbers, not encouragement
If none of that sounded like you, SELV isn't your app. It's built to be exactly right for one kind of person rather than tolerable for everyone.
The tech
SELV runs on Next.js (web) and SwiftUI (iOS), both backed by Supabase (PostgreSQL with row-level security). XP calculations are duplicated client-side for instant feedback and server-side via a Supabase trigger for consistency. When they disagree, the server wins.
The design system is dark by default and data-first, with a real light theme whose colors were re-picked for contrast rather than tinted down from the dark ones. Numbers are always in JetBrains Mono, prose always in DM Sans. Every visual decision serves the same purpose: making the data easier to read.
Want to try it?
SELV is in private beta. The first 500 on the waitlist join as founding members: early access, your name in the credits, and the first invitation to the Founders Circle when it launches.
