How it works

Three steps, every day

No plans, no rigid schedules — just a target you set once and a number you log each day.

01

Say what you're committing to

Name the habit, set a daily target and pick a unit — minutes, liters, steps, sets or a simple done/not done.

02

Log what you actually did

Tap the checkbox, adjust the number if you did more or less. Entries add up within a day, so partial progress still counts.

Watch the chain grow

Streaks, a 15-week heatmap and completion stats build up automatically — the record you're chasing is your own.

Why JASHT

Built around one idea: don't break the chain

Everything in JASHT exists to make today's entry easy and yesterday's progress visible.

🔥

Streaks that mean something

Consecutive days count toward a running streak. Miss a day and it resets — but your longest streak is kept forever.

🗓️

15-week heatmap

Every habit gets a history grid shaded by how much you logged, from Less to Top, so patterns jump out at a glance.

🎉

A moment when you hit target

Cross your daily target and a confetti celebration marks it — a full trophy when every habit is done for the day.

📖

FAQ

Questions people ask before they start

The short version: tracking is free, nothing leaves your device unless you turn on sync, and you can start in the browser without signing up.

What does JASHT cost?

Tracking is free — permanently, not as a trial that runs out. Unlimited habits and entries, streaks, the heatmap and every statistic cost nothing, work without an account, and show no ads. The one paid feature is syncing your data between devices, which is an optional subscription.

What is in the sync subscription?

A subscription keeps your habits, entries and history in step across every device you sign in on, through your JASHT account. The price and billing period are shown before you confirm the purchase, and you can cancel any time from your App Store account settings. Accounts created before sync became a paid feature keep syncing at no cost.

What kind of habits can I track?

Anything you can put a number on — reading in minutes, water in liters, a run in kilometers, push-ups in sets, steps in steps — or a plain done/not done for habits that have no unit. You set the daily target yourself when you create the habit.

What happens to my streak if I miss a day?

A streak counts consecutive days where you hit your target, so missing a day resets the current streak to zero. Your longest streak is kept forever, and the 15-week heatmap still shows every day you logged something.

Do I need an account to use JASHT?

No. JASHT works without one, and your habits stay on the device you use them on. An account — an email code, Google or Apple — is only needed for syncing between devices, which is the paid part.

Who can see my habits and entries?

Only you. Without an account nothing leaves your device at all. With sync switched on, your habits and entries are scoped to your account alone — never shared with other users, sold, or used for advertising. You can export or delete your data at any time.

Which platforms and languages does JASHT support?

Today JASHT runs in any modern browser through the web app — the complete app, nothing to install. The iOS and iPadOS app is coming to the App Store soon; an Android version may follow later. The interface is available in English and German, with light and dark mode.

Does partial progress count?

Yes. Entries add up within a day, so logging 10 minutes in the morning and 10 more in the evening counts as 20 toward a 20-minute target.
