## What is By Day?

Pick something to improve. See whether it moves.

By Day turns one health goal into a focused sprint with a clear daily plan. Choose a sprint for sleep, recovery, activity, focus, or stress. Each plan breaks the goal into tasks, and Today keeps what is due now separate from anything carried over.

PLAN THE WHOLE SPRINT

View the plan as a calendar, check the workload for each day, move unfinished tasks to a realistic date, and skip what no longer fits. When a sprint ends, close it out and keep the recap in your history.

SEE YOUR PROGRESS

Connect Apple Health or Oura on iPhone. By Day compares recent measurements with your baseline and configured target, shows how much data supports the result, and explains when a finding is still forming. Connected health data is optional.

KEEP WORKING OFFLINE

Complete tasks and write notes without a connection. By Day saves changes on this device and sends them when you are back online.

BY DAY EXPLORER

Explorer adds the full guided sprint catalogue, advanced trends, and connected health controls. Monthly and yearly plans are available through the App Store. Payment is charged to your Apple ID after confirmation. Subscriptions renew automatically unless canceled before the current period ends. Manage or cancel in your App Store subscription settings.

By Day is intended for ages 13 and older. It is not a medical device and does not diagnose, treat, cure, or prevent any condition. Speak with a qualified health professional about medical decisions.

## Version history (last 2 releases)

### 1.0.1 — 2026-09-25

Programs are easier to follow. Every task now comes with plain instructions, optional tasks are labelled, and each program shows what it asks of you before you start.

Sleep is now two programs, Fall asleep faster and Wake up rested, and there is a new program for switching off in the evening.

On day 7 of a program you get a short check-in to say how it is going.

Fixes and polish throughout.
