“When are you free?”, asked forty times a year

“When are you free?” — then four emails, two of which cross in the post, and a time that was open when you suggested it and isn’t by the time they reply.

The industry’s answer to this is the booking link, and it works. It also means handing a company a permanent connection to your calendar, and letting a stranger write into your week without asking. Plenty of people quietly decide the back-and-forth is the lesser evil, and go on spending twenty minutes a week on it.

Step one: make your free/busy true

Before any of this is worth automating, one calendar has to know the whole truth. If your work commitments live in a calendar your personal device treats as optional, every availability answer you give is a guess. Mirror the calendars you don’t control into one you do — busy-only is enough — and the free time you see is actually free.

That alone kills most of the back-and-forth, because the majority of rescheduling is not a negotiation. It is you having offered a time that was already taken in a calendar you weren’t looking at.

Step two: send three times, without a tool

Calendar Mirror’s Send times puts your next three free times on the clipboard, ready to paste into a message. No link, no service, no page — just three times that are true because they were worked out on your device against the calendar you just made honest.

Step three, if you’re asked often enough: a request page

If “when are you free” arrives weekly rather than yearly, there is a subscription you can turn on from inside Calendar Mirror: AskWhen.me. It is deliberately not a booking link.

There is also a link you send to one person: it opens once, for a week, for them — so a forwarded message isn’t an open door — and because you sent it yourself, a still-free time can be answered without a round trip.

Pricing, plainly. Calendar Mirror is $2.99 once, for iPhone, iPad and Mac. AskWhen.me is a separate subscription you turn on from inside it: free for 90 days, then $19.99 a year, one subscription across all your devices. Until you turn it on, Calendar Mirror makes no network request at all.

What this doesn’t fix

If what you want is a form that books itself into your calendar with no confirmation from you, this is the wrong product, and that will not change — it is the one design decision the whole thing is built around. The comparison pages name the tools that do it properly, including the free one. What you get here instead is a week where nothing appears that you did not personally agree to.
