01 — Calendar to alarm

Your calendar. Now impossible to ignore.

Go Time works automatically with the calendars already on your iPhone or iPad, turning the events that matter into real alarms that ring through silent mode and Focus. Customize calendars, timing, sounds, and Smart Rules so the right events get through—and everything else stays quiet.

How it works

A calendar event becomes a moment you cannot miss.

Go Time keeps the path short: choose the events, set the boundaries, then let the alarm do its job.

  1. 01

    Choose the calendars that matter.

    Start with the calendars you want Go Time to watch, and leave the rest alone.

  2. 02

    Set the rules around your day.

    Pick lead times and quiet exceptions so an alarm earns its interruption.

  3. 03

    Go when it rings.

    Open a meeting link from the alarm and move from calendar to call without hunting.

The controls

Decide what earns an interruption.

The details are where a useful calendar alarm stays useful. Each control is built to help you hear less, not more.

Built for trust

Dependable alarms. Private by design.

Go Time is built on Apple's native AlarmKit and processes your calendar entirely on your device.

Powered by iOS AlarmKit.

Go Time uses Apple's native AlarmKit API to schedule real system alarms, not ordinary notifications. With Alarm access enabled, important events are designed to ring through silent mode and Focus.

Read the reliability details

Your calendar events stay on your device.

Go Time reads and filters calendar events locally on your iPhone or iPad. It has no account, tracking, advertising, or server-side calendar storage, and the app never uploads your event data.

From the founder

“A calendar knows where you need to be. The missing piece is an interruption you can actually notice — and enough restraint to make it welcome.”

Questions & answers

Go Time, in plain language.

The practical details: quiet modes, reliability, privacy, subscriptions, and the iPhone or iPad it runs on.

Will Go Time ring when my iPhone or iPad is on silent or in Focus?

Go Time uses the alarm experience on iPhone and iPad for events you choose to track, so its alarms are designed to get through the quiet modes that can hide ordinary notifications. Your alarm and calendar permissions must remain enabled for that to work.

Are Go Time alarms guaranteed to fire?

No. Go Time is a helpful aid, not a guaranteed alerting system. Alarm delivery depends on iOS, AlarmKit, calendar data, permissions, and your device state, so keep another reminder for time-critical or safety-critical events.

What does Go Time do with my calendar data?

Go Time uses calendar access on your iPhone or iPad to decide when to schedule alarms. It has no account, tracking, or advertising, and calendar data and app activity stay on your device. Feedback only leaves your device if you choose to send it.

Which meeting providers can I join from Go Time?

When a calendar event includes a supported link, Go Time can open Teams, Zoom, Google Meet, Webex, FaceTime, or Amazon Chime from the alarm. Availability depends on the event link and the corresponding app or service on your device.

What is the difference between Go Time Free and Pro?

Free covers one calendar with a fixed five-minute heads-up and the core alarm experience. Pro adds more calendars, flexible timing, filtering rules, and sound controls for people who want Go Time tuned to a fuller schedule.

How does the trial work, and can I cancel?

Eligible users can receive a seven-day free trial of Go Time Pro. Pro is an auto-renewing subscription, and you can manage or cancel it at any time in your Apple Account subscription settings. Cancelling stops future renewals while access continues through the current paid period.

Which devices and system versions does Go Time support?

Go Time supports iPhone and iPad running iOS/iPadOS 26.1 or later. It also needs calendar and alarm permissions; if either permission is denied or revoked, Go Time cannot provide its core alarm features.
