CatchUp is a social networking app available for iPhone that allows users to keep in touch with their friends, family, and business associates. Developed by Ryan Token, this free app is supported by tips and does not contain any ads.

With CatchUp, users can set reminders for specific contacts in their iOS Contacts list and receive notifications when it's time to catch up with them again. These reminders can be set as recurring events, such as every week or month, or on a custom day chosen by the user. Users also have the flexibility to choose the time of day they want to receive the notification.

One of the standout features of CatchUp is its support for both light and dark mode, allowing users to personalize their experience. Additionally, users can receive reminders even when not connected to the internet, ensuring they never miss an opportunity to catch up with someone important.

CatchUp also offers customization options for nearly every reminder choice, giving users the ability to tailor their experience to their preferences. Furthermore, if users have birthdays or anniversaries set for their contacts in the iOS Contacts app, CatchUp automatically generates reminders for these special occasions.

From a technical standpoint, CatchUp utilizes SwiftUI for 99% of its user interface, providing a smooth and intuitive experience. All data is stored locally on the user's device using Core Data, ensuring privacy and security.

In conclusion, CatchUp is a free and ad-free social networking app that helps users stay connected with their contacts. With its customizable reminders, support for light and dark mode, and local data storage, CatchUp is a reliable and user-friendly tool for keeping in touch with loved ones and business associates.
