OpenClaw cron jobs vs phone reminders: what's your workflow?

Still figuring out the best way to use OpenClaw's cron feature alongside regular phone reminders. Do you set everything up in OpenClaw cron jobs, or mix it with your phone's native reminder system?

I like that cron jobs can run even when I'm not actively chatting, but sometimes I just want a quick 'remind me in 20 minutes' without setting up a whole scheduled task. How are you balancing the two?

Also curious if anyone's found clever uses for recurring cron jobs beyond the obvious daily/weekly stuff.
