Hundredz is a quiet, private 100-year journal built on the belief that every life is unique. It’s born from your birth date and maps out 36,500 days in a single grid, letting you see your life as a whole. I started building it after turning 30 and realizing I couldn’t clearly remember where the last decade went — the small moments, the struggles, the growth. No streaks. No subscriptions. Your data stays on your device. I’m here to hear honest feedback.

Hey Product Hunt 👋 I’m the solo maker behind Hundredz. I built this app after realizing I couldn’t clearly remember where my 20s went — not because life wasn’t happening, but because it passed quietly. Hundredz isn’t designed to push you to write every day. There are no streaks, no reminders, no social pressure. Your days are laid out whether you fill them or not — it’s your life, at your pace. I’m sharing this here mainly to hear honest thoughts: • Does the 100-year grid feel meaningful or overwhelming? • Is the calm, non-pushy approach refreshing — or confusing? • What would make this something you’d actually return to years from now? I’ll be around all day and genuinely appreciate any feedback — positive or critical.
