Why a habit tracker doesn’t need a subscription
A habit tracker stores a small amount of data: your habits and which days you did them. Once keeps all of it on your iPhone. There is no account and no server of ours holding your history, so there is no ongoing service to pay for every month.
That is why Once is a one-time purchase rather than a subscription. You pay once if you want more than the free plan, and it stays unlocked.
What’s free, and what Once Unlimited adds
The free plan is the whole daily routine for up to 3 habits: one-tap check-offs, streaks, repair days, reminders at any time, the weekly overview, achievements, and backup export and restore. It doesn’t expire.
Once Unlimited removes the 3-habit limit and adds the Month view, the Year heatmap, a custom streak goal and more icons and colours. It is one purchase, and Family Sharing lets the rest of your family group use it too.

If you want a fourth habit or the Month and Year views, Once Unlimited is a single one-time purchase.
A private habit tracker with no account
Everything you enter in Once stays on your device, and in your iCloud or computer backups if you use them. BuzzzMind never receives your habit data, and the app has no analytics, advertising or tracking SDKs.
The only network request is for the purchase: when you buy or restore Once Unlimited, the app confirms it with a payment service using a random ID. No habit data is ever part of that.
Works offline, moves with you
Checking off habits, streaks, reminders and every overview work without a connection. Buying or restoring Once Unlimited needs the internet.
Changing phones? Export a backup file from Once and restore it on the new iPhone, or let your usual iPhone backup carry it across.

In the app
What you get in Once
Each habit is one tap a day, or several for things like glasses of water. Every habit shows its current and best streak, its last 30 days, a reminder and the days it repeats on.
Miss a day and a repair day keeps the streak going. Forgot to log? Fill in the day. Achievements mark the milestones, from a 3-day streak to a full year.
