About SELV.
SELV started as a Google Sheet.
Seventeen habits. Weighted by importance, scored daily, summarized as a completion percentage. After three months of running this spreadsheet, the creator realized something: this wasn't a habit tracker. It was a character sheet.
The frustration with existing habit trackers was clear: they were either too childish (cartoon pets, pixel art quests), too punishing (streaks that reset on one missed day), or too boring (plain checklists with no accumulation). What was missing was a tool for data-motivated adults. Something that showed you honest numbers, tracked cumulative progress, and treated missing a day as information rather than failure.
SELV is that tool.
What we 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. We obsess over reducing the steps between "I want to log" and "done."
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 those resonated, SELV probably isn't for you — and that's okay. We're not trying to be everyone's app. We're trying to be exactly right for a specific person.
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-only, data-first. Numbers are always in JetBrains Mono. Prose is in DM Sans. No light mode. No cartoon elements. Every visual decision serves the purpose of making data easier to read and understand.
