What actually happens.
Six steps, start to finish. Nothing here is a mock-up of a feature that doesn't exist yet — this is what the app does today.
One permission, and it's a narrow one.
Google asks you to approve a single scope: calendar.app.created.
That grants the ability to make a new calendar and manage that
one — and nothing else.
A calendar called Merged Calendar appears in your Google Calendar straight away. Rename it to whatever you like; it's yours.
- Make secondary calendars Granted
- Manage events on them Granted
- Read your existing calendars Not asked
Paste the sharing link.
Every calendar app can publish a private link to its events — Outlook calls it an ICS link, Google calls it the secret address in iCal format. Paste it in and the app checks it before saving, so a wrong link tells you immediately rather than failing silently at 6am.
The tag is prefixed to every event from that source, and the colour is what you'll see in Google Calendar. Add as many as you like.
Everything lands in one place.
Wednesday
The alarm goes off.
This is the part that isn't a normal reminder. A couple of minutes before the meeting — you pick how many — your phone sounds, and keeps sounding until you actually acknowledge it. It comes through on silent.
That's delivered through Pushover, a one-off cost on their side. Connecting it is one tap from the dashboard — no keys to copy. All-day events don't do this: holidays, deadlines and leave get one calm notification in the morning, at an hour you choose.
Sounding on your phone, bypassing silent mode. It repeats until you acknowledge it here or in Telegram.
Fix the names your calendars insist on.
Shared calendars are full of events called Busy, Untitled event, or a meeting-room booking code. Rename one — in the app or in Google Calendar — and HeyCalendar keeps your title on every future sync, even when the feed keeps sending its own.
Recurring series and one-off events are listed separately, and titles for one-offs that already happened are tucked away so the list doesn't fill up with history.
Recurring
Ask it what's next.
Optional and free. Link the Telegram bot in one tap and you can ask what's on without opening a calendar at all — useful on a phone you don't want to unlock properly, or a desktop where Telegram is already open.
It also mirrors your alerts as ordinary notifications, so you can run it instead of Pushover if you'd rather not have the loud alarm at all.
