On Sandflow, Krist contributes to practical guidance about iPhone screen time, app usage awareness, digital wellbeing, and the privacy tradeoffs behind habit tracking. The goal is to explain how people can use Apple-native tools like Screen Time, Shortcuts, Dynamic Island, Live Activities, and widgets without turning phone usage into another complicated system.
Articles are written for readers who want clearer phone habits, less unconscious scrolling, and honest explanations of what Sandflow can and cannot track on iOS.
This author page is part of Sandflow's editorial transparency, so readers can understand who is behind the advice, why the topic matters, and how product experience shapes the recommendations.
The editorial standard is to keep advice practical, avoid exaggerated claims, and separate what Apple Screen Time can do from what Sandflow adds with real-time timers and user-controlled automations.
