See your day through — without missing what matters.
Smastar keeps your day free of gaps, from your morning wake-up through everything that follows. It wakes you with your schedule read aloud, then keeps you ahead of your events and tasks — catching missed calendar entries and forgotten items before they happen. Built entirely on Apple's native frameworks. Your data stays on your device.
■ Never miss an important event across multiple calendars
When work and personal calendars are split across Apple, Google, and Outlook, it's easy to miss a key meeting. Smastar automatically brings together every calendar on your device in one view. Set up to 3 pre-alarms for any event — including tomorrow's, so you can prepare the night before — so "it already started" never happens again, with a spoken reminder at the start time, too.
■ A checklist to stop forgotten items on the go
Ever dozed off on the train and scrambled at your stop, leaving something behind? Add a checklist to any to-do. Items like "umbrella," "documents," or "keys" appear right with your alarm — catching those slips at the moment you act, before you leave or step off.
■ Stay on top of what needs doing
・To-Dos: Start times, repeats, up to 3 pre-alarms, checklists, notes with tappable links, and completion tracking. Even with the alarm off, you're notified at the start time.
・Habits: Track your daily streaks, reflected in the next morning's briefing.
■ Wake up clear-headed, to your voice
・A full morning briefing: time, weather, today's schedule, habits, and to-dos — so you wake up taking in the day, not hitting snooze.
・Paste a link into a to-do and it appears on the alarm screen — tap once to stop the alarm and go straight to the news, the route, or whatever starts your day.
・Toggle Alarm Sound and Readout independently for each alarm, with sound selection. Turn both off for silent, vibration-only alerts.
■ Health first — check in before your day begins
Nothing matters more than your own health. If you use Apple's Health app or an Apple Watch, Smastar's Health tab shows your resting heart rate, heart rate variability (HRV), VO2 max, walking heart rate, BMI, and sleep duration at a glance. Did you sleep well last night? Is your body ready? Get a quick read before you start your day.
■ Focus and rest
・Built-in focus and sleep music player, always a tap away.
■ Privacy first
・No third-party SDKs, ever.
・Location, calendar, and health data are processed on your device and never sent anywhere.
From your morning wake-up to your daytime planning to your evening wind-down — Smastar quietly helps you see your day through.

Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
- Peace of mind if you stop it half asleep: after you stop a wake-up alarm, a backup rings after each snooze interval, up to 2 times, wherever you stop it (Lock Screen, buttons, Apple Watch, or in the app). Stopping the alarm doesn't cancel it. Open Smastar to cancel the rest. If another wake-up alarm follows within 60 minutes on the same morning, backups ring only after the last one. You can turn this off in Settings.
- When you open Smastar, a pop-up tells you about any backups or snoozes still to come, and you can cancel them right there.
- When a to-do alarm rings, the screen now offers Done, Reschedule, and Close.
- Tap a to-do's circle in a list to mark it done, and undo it right away.
- Checklist ticks are now saved, and you can tick items right from the lists on Home and the Daytime tab. When every item is ticked, the to-do shows "All checked."
- Phone numbers and addresses in a to-do's memo are now links too, so you can call or open Maps from them.
- While the Health tab is hidden ("Show Health tab" off in Settings), Smastar doesn't read Health data or ask for Health access.
- Deleting your account now erases all Smastar data on this device.
- Fixed an issue where opening Smastar from an alarm after a restart, before your first unlock, could crash the app.
- Fixed an issue where scheduled alarms could be removed when the subscription status couldn't be checked.
- The Save button is easier to see, and layouts no longer break at the largest text size.
- Improved the readout, including how Japanese honorifics such as 様 and 氏 are read.
