WhatDate: Reminder with Alarm

Arc Sini

About this app

WhatDate brings your to-do list, calendar and reminders together, with alarms that work offline. Set recurring reminders for bills, birthdays, appointments and everyday tasks, with flexible schedules and no sign-up required.
It's free. No account, no login required.

TASK REMINDERS AND FLEXIBLE REPEATS
Each reminder is a WhatDate: one event or task, or a whole series, and every occurrence gets its own alarm or notification. You're not only reminded but can track them: a reminder log records done, snoozed or postponed, plus your notes.
• Daily work, chores, habits, TV shows and trips
• Birthday and anniversary reminders
• Monthly bill, EMI, rent and payment reminders
• Appointments, classes, meetings and calls
Repeat every N days, weeks, months or years at a set time, on selected weekdays, on the 2nd and last Friday, or on the last working day of the month. Stop after a number of times, on a date, or never. Create reminders by voice, with offline recognition where supported.

OFFLINE REMINDER APP, NO CLOUD ACCOUNT REQUIRED
Offline mode is the default, and personal reminders work fully offline.
• No account, no sign-up, no analytics, no tracking
• Reminders stay on your phone in an encrypted database, leaving it only when you share or back them up
• App lock with fingerprint, face or screen lock
• Password-protected backups that only you keep
Internet friend connections, pack downloads and web links need connectivity.

SHARED REMINDERS FOR FRIENDS
Create reminders right in a friend's WhatDate app, and keep the copies you shared up to date.
• Your changes update the reminder you shared when your friend next syncs. If they edit it, it becomes their own copy
• Share an event file in any messaging group; resend it after a change to update friends' copies
• Photos travel resized, with location data removed
Add friends by invite link, QR code or optional @handle; no phone number, no access to contacts. Offline, friends connect nearby by QR code or Google Nearby and sync over Wi-Fi or Bluetooth. Online, sync also runs through a relay that can't read your WhatDates. End-to-end encrypted sync. Private reminders are never shared.

ALARMS AND NOTIFICATION SOUNDS
Reminders can Ring (full-screen, like a phone call), Play Once (a short tune), Vibrate or stay Silent. By default, Private reminders ring, Friends reminders play a short tune once and Public reminders vibrate, ideal for public holidays. Change the sound for each type in Settings.
• Remind early, then again at the exact time
• Snooze when busy, postpone to reschedule, or mark done, handy for daily habits
• Optional morning briefing

ACT WHEN THE REMINDER ARRIVES
One-tap actions that you trigger yourself:
• Call or message
• Open a link, an app or your payment app
• Open a map or start navigation
• Tick off checklists inside a reminder, fresh each time

IMPORT CALENDAR EVENTS AND CALENDAR PACKS
• Import calendar events from calendar apps that export iCalendar (.ics) files
• Festival and holiday reminders from calendar packs at whatdate.app: Diwali, Holi, Eid, Christmas, Easter, Ekadashi, Amavasya, plus public holidays, international days and sports fixtures
• Each date credits its source, such as GOV.UK bank holidays, India's Department of Personnel and Training and UN international days
• Packs of 1,000+ dates import in one go
• Keep irregular dates together in one reminder series: where a pack offers "One series in WhatDate", dates that follow no rule stay together as one Dynamic WhatDate. Ordinary downloads add one WhatDate per date
