## What is Strideline?

A study schedule app that shows, at a glance, what you did today and how long it took.

Strideline: Study Pacer is built for 4th–6th grade students preparing for entrance exams, and for the families supporting them. The loop is simple: plan in the morning, tap to start the timer, tap to stop. The app quietly records the rest.

———————————
THREE DESIGN PRINCIPLES
———————————

▸ Show what was actually done
No flashy auto-scheduler. You line up the day's blocks in the morning, and the app preserves exactly when each one started and ended. A central progress ring plus a vertical timeline shows today's reality in a single glance.

▸ No-type UX
Starting a timer, stopping it, swapping blocks, inserting a break — almost everything is a tap or a gesture. Typing is required only when you first register a textbook; after that, "recently used materials" gives you a one-tap add.

▸ Beauty as fuel for daily practice
A glass-modern iOS-26-era UI. A subtle pulsing glow on the block that's running. The honest satisfaction of a check mark when it's done. Themes from snow white to true midnight. The grind of exam prep gets one small, quiet joy added to it.

———————————
KEY FEATURES
———————————

• Time blocking: planned blocks bound to recorded actual times
• Timer: tap ▶ to start, ■ to stop. Live Activity keeps running when the app is closed
• Progress ring: today's completion rate and total time at center
• Vertical timeline: the whole day in one scroll
• Material library: one tap to add a recently used textbook to today
• Countdowns: days until mocks, exams, results — on home screen and widget
• Statistics: subject-stacked bar charts, donut, daily trend, weekday averages
• Calendar: 13 months vertically scrollable, heatmap, monthly summary
• Weather overlay: weekly view with current location or Tokyo forecast
• Multiple profiles: switch between siblings (2nd+ profile requires Pro)
• Home Screen widgets: today's plan and countdown
• Lock Screen Live Activity: running timer
• Start chime / overrun prompt

———————————
