What's new v1.0.0
Constanza 1.0.0.
- One fewer permission: the network-state access that a bundled Android library added is gone. Constanza has never had internet access, and now it cannot even check whether you are connected.
No accounts, no cloud, no ads, no tracking.
About Constanza - Good habits
Constanza is a habit-tracking app that opens and works in seconds. No account, nothing synced to any cloud, no ads and no analytics: it does not even declare the internet permission, so it could not connect even if it wanted to.
Each habit gets its own colour -from a palette of 21, or a custom one from its own hue/saturation/brightness picker- and its own schedule: every day, several times a day, a number of times a week, specific days of the week, a day of the month, or every N days. Any schedule can carry one or several reminder times.
The Today screen groups what is due now, what is due later, and what you have already answered, and you can step back to any past day to see what happened. Answering is one tap: Yes or No, no dialog to open. And when a reminder arrives, you can answer it right from the notification -Yes, No or Snooze- without even unlocking the phone.
A day you do not answer does not disappear: at midnight, any slot left unanswered becomes "Missed". Constanza does not hide what you let slip to make you feel better about it; it records it, and that record is what the streak and the compliance number are built from. Progress shows the current streak, the best streak, and the last-30-days compliance percentage for each habit.
Reminders survive a phone reboot and a time or timezone change: you do not need to reopen the app to keep them firing. If your phone does not grant the exact-alarm permission by default, Constanza tells you without blocking anything and takes you to the setting; if you would rather not grant it, reminders still arrive, just with a few minutes of slack.
Every night, at 23:00 by default, a review notification reminds you what is still open that day -or only when something actually is, if you would rather set it that way. And in Settings you can change how long a snooze lasts, pick the language (following the system, English or Spanish), and export or import all your data as a file, through the system's own file picker: it is your copy, not ours.
The interface is dark, always, with no light mode. That is not an oversight: the background is deliberately neutral so the only colour on screen is the one you gave each habit.
What you get:
- Habits with six schedule types and one or more reminder times.
- 21 colours plus a custom hue/saturation/brightness picker.
- Reminders answered Yes/No/Snooze right from the notification.
- An unanswered day is recorded as "Missed" at midnight, never hidden.
- Current streak, best streak, and last-30-days compliance per habit.
- A nightly review notification, configurable, or only when something is pending.
- Data export and import to a file, through the system picker.
- Reminders that survive reboots and time changes.
- English and Spanish.
- No accounts, no cloud, no ads, no tracking, no internet permission.
