Welcome
Saved on your deviceLocal-firstNo sign-up + optional sync key
Track your challenge without the clutter.
Tick off each calendar day when you stayed on track, when it was tough, or leave it blank. By default it stays local on your phone or computer, and you can optionally back up/restore across devices with a private sync key from Settings.
Calm and clear
Made for one repeating routine
The flow is always the same: open the app, log how today went, optionally look at your stats. There is no endless feed and no collectible badges—only a calm place to be honest with yourself.
Whatever you log lives in this browser storage on this device until you clear it yourself. We do not send it to the cloud and we do not tie it to an email address.
What you can do here
Simple tools for one goal: stick with your plan
A day-by-day checklist, crystal-clear privacy, and easy charts. Each card below explains one main feature in plain language.
Your business stays yours
No password, no syncing to our servers. Your history is tucked away on this phone or laptop in this browser only—nothing gets uploaded.
Pictures of your progress
Colorful summaries on Report show how many days went well, which were hard, and what is still blank—plus streaks and charts that mirror your taps on Challenge tool.
Keep it simple
Spend energy on your habit, not on learning an app
You choose how long the challenge runs and you get one clear grid plus simple charts. Fewer buttons means less time tweaking settings and more time doing the work that matters to you.

How it works
Three straightforward steps
You only set the schedule once, check in as you go, and peek at summaries when you feel like it. No account to create and nothing to import.
- 01
Pick your dates
Open Settings (top menu). Name your challenge (one at a time), edit length and optional day one, then tap Save settings—you’ll confirm before anything is stored. Until you’ve begun, day one also follows IST “today” on each visit if you never save a different date. Length must stay between 7 and 365 days or save is blocked.
- 02
Check in each day
Open Challenge tool from the menu. For each calendar day tap either a win (green), a slip (pink), or clear it again if you tapped wrong. Updates stay only on this device—we never sync them.
- 03
Look back anytime
Report shows bars and totals so you see the big picture. Change length or start date in Settings, confirm, then save. Start date locks after you begin; use “Reset all settings and progress” (with confirmation) to clear everything—21-day length, day one becomes today, empty day cards—no undo.

The Quiet Appeal of Starting Over
Starting over promises innocence — a clean page with no failure attached. But to feel clean, you give up everything you've built. We end up with a collection of Day Ones and very few Day Twelves.

ReflectionsRest, or Avoidance?
Rest is quiet. Avoidance comes with a lot of explaining. The volume of justification is usually the tell — real rest doesn't need a lawyer.

Important: local-first data (optional sync key backup)
There is no sign-in screen and no automatic cloud copy. By default your progress stays on this device/browser unless you manually back it up from Settings with your sync key.
You always see your latest local history instantly in this same browser on this same device.
Switching phones, tablets, or laptops will not carry your list over by itself unless you restore with a sync key.
If someone (or you) clears browsing data, cached files, or cookies, your streak can disappear.
Deleting the browser app or factory-resetting the gadget can erase what you saved.
If you clear browser data before making a sync backup, we cannot recover it for you. Keep your sync key private; anyone with that key can restore your backup.
