- Can call you with a reminder, which can be more powerful than notifications
- Works across platforms
- Will eventually support more integrations, such as calendars, webhooks, and telegram/whatsapp/etc.
[0]: https://news.ycombinator.com/item?id=33448262 - Phone call notifications have been quite powerful in practice. I miss push notifications all the time, but a phone call is harder to ignore.
- More powerful scheduling: some filters aren't possible to create (like "last day of month") in the Google Calendar UI
I'm also planning to implement more integrations (webhook triggers, webhook notifications, slack/discord/telegram/whatsapp notifications), which should tip the scales somewhat more. I also want to integrate Google Calendar at some point, so you could create nudges for all your calendar entries automatically.
