Diem is a straightforward to-do list app designed by Fresh LLC, an award-winning team of designers. The app is available on iPhone and falls under the Business & Productivity category. Unlike other to-do list apps, Diem doesn't require any sign-up or subscription, making it an excellent option for those who value their privacy.

The app's design is minimalistic and elegant, resembling a piece of paper. It has no folders, subtasks, or snooze options, making it easy to use and navigate. Users can add their tasks and swipe to complete them. Diem also allows users to set a single reminder for the entire list, making it ideal for those who don't want to be bothered with due dates.

Diem aims to help users focus on what's important, allowing them to seize the day without any distractions.
