Ever wanted to add a reminder six months before some date? Or 90 days? Or three weeks? Math is hard, yo.

Dejal Preminder makes it easy — simply enter the date of the event, choose how long before that you want to be reminded, and have it add the reminder.

The app offers several common time intervals, like 30 days before, 1-6 months before, or a year before, plus you can choose any custom interval.

Reminders can include or exclude notes or a time, and can be added to any of your reminder lists.

Preminder is available totally free on the App Store for iOS.

Dejal has a reputation for prompt and friendly support. Check out the Preminder Support page for several ways to get assistance from the developer and other customers, to suggest new features or enhancements, or provide other feedback.
