Hi Product Hunt I’m the maker of Akaru, a calendar-based alarm app for iOS. The main idea behind Akaru is simple: your alarm time should be visible on the calendar, without tapping each date. Many alarm apps let you create repeating alarms, and some calendar-style apps let you set alarms by date. But in many cases, you still have to open each day to check what time the alarm is set for. Akaru shows the alarm time for each day directly on a monthly calendar. This makes it easy to see your upcoming wake-up schedule at a glance. It’s useful when your mornings change because of weekdays, weekends, holidays, school events, early meetings, shift work, or remote work days. You can set rules for weekdays, holidays, and special dates, add extra alarms, and tap a date to customize exceptions when needed. This is my first step toward bringing Akaru to users outside Japan, so I’d love to hear your feedback. Would seeing your alarm times directly on a monthly calendar be useful for your routine?

the calendar-as-alarm-surface is genuinely the right metaphor — toggling between weekday/weekend rules in stock alarms feels like editing crontab. for the irregular crowd: any plan to import from google calendar so my actual events drive the wake-time?

Thanks — I really like that framing.

Akaru’s core idea is showing each day’s alarm time directly on the monthly calendar, without making you open every date one by one.

Google Calendar import is an interesting direction. I’d probably start with suggested alarms from calendar events, so users can review them before anything is created automatically.

Would you expect this to work from the first event of the day, or from selected calendars / keywords?

@kurisaku  selected calendars + keywords is what i'd use — my work calendar has 9am standups, personal calendar has flights at 5am. 'first event of day' would over-fire on the personal stuff. the review step before creating is the right safety net.

That makes a lot of sense — selected calendars + keywords feels like a better model than simply using the first event of the day.

The flight example is exactly the kind of case I’d want to avoid. If I explore this, I’d probably start with a review-first flow: Akaru suggests wake-up alarms based on selected calendars and keywords, and the user confirms before anything is set.

Really helpful feedback — thank you.

As someone whose schedule changes daily, 'calendar-based alarms' is the feature I didn't know I was missing. It solves the 'forgetting to reset the alarm for an early meeting' anxiety perfectly. Does it sync with multiple calendar providers (e.g., Outlook and Google) simultaneously?

Thank you — that early-meeting anxiety is exactly the kind of problem Akaru is trying to reduce.

Not yet. Calendar sync isn’t in the current version, but it’s a very interesting direction. I’d want to start carefully with selected calendars and suggested alarms that users can review before anything is created automatically.

Multiple providers like Google and Outlook are definitely an important use case.
