Sereliz
Read full descriptionHide full description
Sereliz is a place for the people you already know. There is no public feed, no followers, and no algorithms putting strangers in front of you. You invite someone in person or by email or QR — and that is your circle. We call it Inner Sanctum. Keep the small things you would rather not lose: a photo from the weekend, a short note, a moment that only makes sense to the people who were there. They appear in the order they happened. When you want to talk, there are one-to-one dialogs. The conversation is encrypted, so only the two of you can read it. Your profile stays inside the circle too — name, photo, a few words about you. For close ones, not for the internet. Open Sereliz when you want to know how your people are. Not because something asked you to stay.

Verdict
The clearest difference is update cadence: Sereliz at every 3 weeks against B17.ru's every 11 months. B17.ru's advantage is iOS requirement (13.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
