Someone asks "when are you free?" by email, text or chat. You leave the conversation, open your calendar, come back and type times from memory. WhenFree answers from inside the conversation: switch to its keyboard, tap the times that work, and the exact sentence is typed from your calendar: "Tue 2–2:30pm or Wed 10am work for me (CT)." No account, no booking page. Your calendar stays on your iPhone. THE KEYBOARD: IN ANY APP YOU TYPE Email, chat, messaging apps, your CRM, a web form: anything with a text field. Your open times sit in a row above a full QWERTY keyboard. Suggest picks three good times in one tap; "Not this" swaps one out. Day peek shows what is around a time before you offer it. Plain text, so it works with anyone on any phone or computer. The keyboard never opens other apps, never sends anything anywhere, and works without Full Access. IN MESSAGES: THEY TAP A TIME In Messages, tap +, then WhenFree. Your week appears as a board. Tap the tiles that work and send. If they also have WhenFree, they tap a time and it goes on both calendars. If they reply by text, tap "They replied — add it" and it goes on yours. FOR PEOPLE WHO OFFER TIMES ALL DAY Realtors and agents booking showings, recruiters lining up calls, tutors, consultants, freelancers, small-business owners, parents coordinating the week. YOUR RULES, APPLIED EVERYWHERE • Working hours per day, including evenings and weekends if you want them • Buffers before and after, so travel time is never offered • Minimum notice and a maximum number of meetings per day • Days off and public holidays skipped • Hold time keeps time free for you; it is never offered • Several calendars treated as busy; all-day events handled sensibly MEETING TYPES (PRO) A showing is not a call. Give each kind of meeting its own length, buffers and place. Tap the type, or type "showing" in your message and WhenFree picks it. The place goes on the booked event only, never in the message. WHEN THEY ARE SOMEWHERE ELSE (PRO) Send times in the other person's time zone. Offered times stay marked on your week until they answer, so you never offer the same slot to two people. SIRI, SHORTCUTS, WIDGET AND CONTROL CENTER Ask Siri "When am I free in WhenFree", or tap Copy free times on the widget or in Control Center, and paste anywhere. PRIVATE BY DESIGN No server, no WhenFree account. Your calendar, event titles and messages stay on your iPhone. The keyboard and the Messages extension have no network access at all. The app goes online only if you connect a Google or Outlook account, and then only to read when you're busy and, if you allow it, to add the bookings you make. No analytics, no trackers. App Store privacy label: Data Not Collected. WHAT IT CANNOT DO WhenFree does not book on the other person's behalf, does not send invitations, and does not read your conversations. PLANS Free: 3 sends a month from Messages plus 3 inserts a month from the keyboard, from one calendar, for the current week, using your working hours. WhenFree Pro removes the limit and unlocks every calendar, a month ahead, meeting types, times in their zone, offered times marked, and every rule. • Annual — $29.99/year • Monthly — $4.99/month • Lifetime — $49.99 once, no subscription All three unlock the same thing and support Family Sharing.
