Vimcal

I usually have to combine 3 to 6 different calendars as I have different email/cal accounts for various clients, as well as my own personal ones. And when my clients are on outlook, it usually gets tricky to check my availability as outlook doesn't play nicely with google calendar - and outlook sometimes simply refuses to sync nicely even with apple calendar (usually works, but depends on my client's sec settings - a recent client's outlook worked ok for laptop apple calendar, but failed for my iPhone apple calendar. Annoying!) Vimcal's the only one I've found that gives proper integration between all my calendars. Fast and smooth to use, handy shortcuts for everything. I even quite like the 'focus mode' approach (just background music or white noise and no distractions - could use binaural beats, mind you; and a pomodoro timer would be nice - but unusual and helpful addition) Really nice timezone approach. Uses flexible location names - so just specify the city and it does the rest - why doesn't everything else do that? I can never remember what US city is in which timezone. It even offers booking pages where users can check your availability - so I'm swapping from calendly to this. I don't think it has a general landing page eg /bob/; just the slot-based ones eg /bob/60mins - which is fine for me but might be a problem for some. And it's a tad more awkward than calendly to amend, as there's no way to change your hours on specific date - doesn't matter for me but also might be a problem for some. One other thing it's missing which I'd love, is to have a proper apple watch integration - you get notifications on the watch ok, but there's no watch app. But - love it. Far better than Apple, Google or Microsoft's calendars - and infinitely better if, like me, your calendars are a hot mess of frequently changing accounts.
