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.

Verdict
The clearest difference is in-app purchases: 미즘 at none against BySide's 1. 미즘 also leads on ads (none vs shown). BySide's advantage is update cadence (every 2 days vs monthly). On price, device support and iOS requirement there is nothing between them.
