A photo from your walk. One line before bed. The little things you wish your partner could see. Kalbi gives long-distance couples a private space for those moments. Invite your person and make a place that belongs to the two of you. • Keep their latest photo or note close with a Home Screen widget. • Share photos and little notes, and come back to your earlier exchanges. • Leave a photo or note for later. Choose a time in 15 minutes, an hour, or on a date you pick, then review the exact delivery time before saving. • Count down to your next visit, in Kalbi and on your Home Screen or Lock Screen. • Choose a small shared ritual, with a separate check-in for each of you. • Choose whether to share your latest location and daily Apple Health steps. Photos, notes, countdowns and widgets are free for both partners. Kalbi Pro is optional support for the app, available in Profile. There is no public feed or profile discovery. Location and Health sharing are optional. Step sharing covers daily steps, not workouts, routes or Strava integration. Both partners need Kalbi on iPhone and linked accounts. Scheduled moments remain private to their sender until publication. Notifications and widget refresh timing depend on device and service conditions; iOS controls widget refresh.

Verdict
The clearest difference is in-app purchases: Luvbu at none against Kalbi's 3. Kalbi's advantage is update cadence (every 5 days vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.
