Save a date once and Whenkind reminds you ahead of time. Birthdays, anniversaries, personal milestones and remembrance days, in one calm list that shows what is coming, how many days are left and how many years it has been. Free for your first 10 active dates, then one purchase unlocks the rest. No subscription, no ads, no account. Add a date in seconds. Pick the kind, type who it is for, choose the day and month. The year is optional: without it, Whenkind simply leaves the age out. Add a note, or a photo from your library as the card's cover, or keep the card plain. Upcoming shows what is next. Today, the next 7 days, the next 30 days, and later, with the days left on every card. Choose how far ahead the list looks, from 1 to 12 months. Reminders that fit each date. Set a default once in Settings: how many days before, a second reminder if you want one, and the time of day. Any date can have its own timing. Reminders for saved dates keep working even after you reach the free limit. A line for every year. Each date keeps a history where you can write one short note per year: what you gave, where you went, who was there. It is optional and never asks for anything. There are no streaks and no missed years. Remembrance days stay quiet. Dates for someone you lost get a muted look and neutral wording, with nothing festive anywhere. Bring your dates with you. Import birthdays and anniversaries from your Contacts: you choose which ones to save, and Whenkind only reads them. You can also import a .vcf or .csv file. Duplicates are matched, and you see how many fit in the free limit before anything is added. On your Home Screen and Lock Screen. Small and medium widgets and a Lock Screen widget show the next dates and the days left. Ask Siri: "Add a date to Whenkind." Your dates stay yours. They live on your device and sync through your own iCloud to your other iPhone or iPad. Whenkind has no account and no server of its own that holds them. Export a JSON backup or a CSV file whenever you like. Sync, backup and export are free for everyone. Pricing, plainly. Whenkind is free for 10 active dates. Archived dates do not count, and the yearly notes are never limited. When you reach the limit, nothing is deleted or locked: your dates, reminders, sync and export keep working. Whenkind Unlimited is a one-time purchase that removes the limit. There is no subscription. Light and dark themes, and your choice of accent color. Available in 21 languages.
