Project overview

Focus sessions enforced by iOS, with usage data kept on the device

An iOS focus app awaiting release on the App Store. It uses Apple's Screen Time framework to block selected apps, keeps usage reporting on the device, and supports recurring schedules without accounts or analytics.

Role: Product Design, iOS Development, Marketing Site
Type: iOS App · Consumer Product
Focus: Focus & Attention · Privacy · On-device Analytics
Stack: SwiftUI, Screen Time API, DeviceActivityReport

Challenge

Many focus tools are easy to dismiss or require users to hand over sensitive usage data. We wanted the block to be enforced by iOS, while keeping the reporting useful and entirely on the device.

Solution

Octarine uses the Screen Time framework to enforce sessions and a DeviceActivityReport extension to present usage data without sending it to the app or a server. Saved presets and schedules make the same setup easy to repeat.
