Zync
Counts the days, tracks the habit, shows what it earned you.
Count down to a date or track the days since one. Weddings, holidays, exams, retirement — all on one screen and in a widget on your home screen. Zync was built by Vinci Studio as its own product.
There is no shortage of countdown apps. What sets Zync apart is that it also works out what the counting is worth. Turn the day you quit smoking or cancelled a subscription into a counter, enter the daily amount — and Zync accumulates the money staying in your pocket for every day you keep it up.
The figure on screen is a real calculation: 75 lira a day, 90 days. Not an abstract "you're doing great" message, but a number.
Seven currencies supported; amounts can be entered daily, weekly or monthly.
Counts both ways
Future dates count down, past dates count up. The direction is automatic.
Savings tracking
What the habit you dropped has earned you, updated every day.
Widgets
Home screen and lock screen widgets — see it without opening the app.
Reminders
Per-counter notifications, scheduled entirely on device. Nothing leaves it.
Personalisation
A colour, SF Symbol or emoji per counter; categories and pinning.
Share card
Share milestones as an Instagram story-sized card.
Zync has no server. No account, no email address. Everything you create is stored on your device and, if you choose, synced across your devices through your own iCloud account.
No tracking, no ads, no analytics SDK. Deleting the app deletes your data — there is no copy on our side for you to ask us to remove.
