30daylist implements a 30-day waiting period for any item you consider purchasing. This delay gives you time to reflect on the necessity and affordability of the item before you commit to buying it.
You can enter basic information about the item you're considering. The app also captures your current location, allowing you to find the item's location again later.
After 30 days, 30daylist will send you a notification and display a badge on its icon to remind you that it's time to make your final decision.
Once the 30 days have passed, you can decide if you still want the item. 30daylist can show you the item's location on a map or open its store URL for you. If you no longer want it, you can simply swipe to delete the entry.
