Real screens. No mock-ups.

Why it works
Built for the days you show up.
-
Three editions, one price
Use the App on your laptop and phone, keep the Google Sheet in your Drive, or open the Excel file. All three come with every purchase.
-
One tap to check in
Tick a habit, step a count up or down, or log minutes. Undo is one tap away, and you can fill in a day you missed from the calendar.
-
Streak rules that are fair
Daily habits count days in a row, chosen-day habits skip their rest days and times-a-week habits count weeks. Today never breaks a streak while it is still open.
-
Reminders in your calendar
Give each habit a reminder time and export one calendar file. Your habits show up in the calendar you already use, with an alert.
-
See what works
Completion per week, your best weekdays and your steadiest habits, from your own check-ins. Start a 21 or 30 day challenge when you want a push.
-
Your routine stays private
The App keeps your data in your own browser, never on our servers. Back it up in one click and restore it on any device.

A few good answers
Questions, answered.
Delivery, devices, updates and your data. Still curious? We reply to every email.
Ask us a questionHow do I get my files?
Right after checkout we email you a Darzen username and password. Sign in to your Darzen account to download the App and the Excel files, and to make your own copy of the Google Sheets edition.
Which edition should I use?
All three come with every purchase, so you do not have to choose. The App feels like software and works offline, Google Sheets lives in your Google account, and Excel is a file you keep.
Which version of Excel do I need?
Excel 2010 or later on Windows and Mac, or Excel for the web. The workbook has no macros.
Does the App need the internet?
Only once, to sign in with the login we email you. After that it opens from the file on your device and works offline.
Where is my data kept?
In the browser on your own device, never on our servers. Save a backup file in one click and restore it on any device or browser.
Can it remind me to do my habits?
Yes. Give a habit a reminder time and export one calendar file. Your habits go into the calendar you already use, with an alert at that time. The spreadsheet editions do not send reminders.
What happens if I miss a day?
A daily habit starts a new streak, and your best streak stays on record. Habits set to chosen days skip their rest days, times-a-week habits count weeks, and today never breaks a streak while it is still open. Forgot to check in? Fill in the day later.
Does it work on my phone?
The App works in your phone's browser and the Google Sheets edition works in the Sheets app. Sign in on up to two devices.
How do updates work?
Updates are free. When a new version is ready, it appears in your Darzen account and the App tells you.
Can I get a refund?
See our refund policy, linked next to the price. Try the live demo first so you know exactly what you are getting.
One app. One Google Sheet. One Excel workbook.
