## What is BySide?

Keep the days that matter by your side.

The day you met, Mom's birthday, your wedding anniversary, an exam or a trip. BySide counts down to — or up from — the days that matter, and reminds you before they arrive.

■ Timeline and calendar
• See upcoming days grouped by this week, this month and each month, with a badge on 100-day milestones.
• Jump to any month or year in the Calendar tab, and tap a date to start a new D-Day.
• Holidays from your device calendar appear in the calendar and widgets.

■ A D-Day album decorated with your photos
• Add a photo to each D-Day and browse them as photo tiles, like an album.
• Crop and rotate each photo to fit just right.
• Choose from four views — list, cards, album or calendar. Your last view is remembered.

■ A reminder every 100 days
• Count your days together with D+, and 100, 200 and 1,000-day milestones are calculated for you.
• Get reminded on the day, and 1, 3 or 7 days before.
• Set a different reminder time for each D-Day.

■ Repeats on its own
• Birthdays and anniversaries repeat yearly; paydays and card bills repeat monthly.

■ Your first D-Day, together
• When you first open the app, just pick what kind of day it is. Relationship, birthday, or exam & deadline — the settings are filled in to match.

■ Home screen widgets
• One D-Day shown big with its photo, several D-Days in a list, or this month's calendar.
• Style the widgets to match your wallpaper.
• Show the days left for a chosen D-Day as a badge on the app icon.

■ Share as photo cards
• Make a card with a photo background and send it to friends in your favorite messaging or social apps.
• Save the card image straight to your photo library.

■ Neat and tidy
• Create your own categories like Couple, Family or Work, with colors and emoji
• Sort by nearest, manually, recently added or by name, and pin to top
• D-Days you won't need afterward, like exams and deadlines, can be cleared automatically the next day
• Memos, search, month/year view and dark mode

■ Use with peace of mind
• Start right away, no sign-up
• Your D-Days and photos are stored only on your iPhone
• Backup files include your photos, so everything comes with you to a new phone

■ Remove ads with a one-time purchase
• Removes all ads in the app.
• Not a subscription — no recurring charges.

All features are free; the free version shows ads.
