NICE - Habit Accountability

NICE is a habit-accountability app that flips the script on positive reinforcement. Most habit apps shower you with confetti and pep talks. NICE doesn't. It sits beside you with a quiet, deadpan voice — a Drill Sergeant, a Disappointed Mom, Your Ex, Your Future Self, or Your Manager — and reminds you of the contract you signed with yourself this morning. It's a behavioral-economics experiment in app form. Every mechanic maps to research, not vibes: • Loss Aversion (Kahneman & Tversky). Completion isn't celebrated; missing is what gets framed as the loss. "Didn't lose today" lands harder than "great job." • Implementation Intentions (Gollwitzer). Habits are written as if-then contracts: "After work → Put on workout clothes by 8pm." The trigger is mandatory. • Commitment Devices (Ariely / Thaler). At habit creation, you pick a self-penalty that activates if you fold: tomorrow's intensity bumped, an extra midday reminder, or the widget pinned to your lock screen until you complete it. • Accountability Effect. Choose one of five personas — each with a distinct voice, written by hand, hundreds of lines deep. The accountability is structured, opt-in, and revocable at any time. NICE is intentionally uncomfortable. The discomfort is the mechanism, not a side effect. Try one persona for a full week before deciding it's not for you — that's what the research says about real behavior change. What you get: • Five hand-written personas (Drill Sergeant, Disappointed Mom, Your Ex, Future You, Your Manager) — English/Korean for each • Home-screen widget showing your 14-day track record • Local notifications timed to your deadlines — no cloud, no servers • Per-habit commitment device (you choose the cost of folding) • One-tap completion with a 1.5-second "I'll let you off today" verdict from your chosen persona What you don't get: • An account or sign-in (there is none) • Servers (there are none) • Analytics or tracking (there is none) • Streak gamification or social features Your habits, your history, your intensity, your persona — all stay on your device. NICE has nothing to upload because NICE collects nothing. Privacy policy: https://gist.github.com/shevchekun/081524a69f35e4a8cf2b3861e6168b98 iPhone only. iOS 17 or later.
