RiseSlow — The habit tracker that doesn't punish you.
Most habit trackers use binary streaks: miss one day, lose everything. RiseSlow uses exponential decay instead. One missed day barely moves the needle. Your streak bends, it never breaks.Free, browser-based, no account needed, privacy-first.Built with Next.js, deployed on Vercel.
