Strideline: Study Pacer

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.
