B612 is the camera app behind countless Instagram stories and TikToks across Pakistan — it applies Snapchat-style AR filters in real time so what you see is what you post. Beyond the fun lenses it has grown into a genuine editor, with daily-trending effects, AR makeup, custom filters and pro colour controls under the hood. Pros: one of the fastest filter pipelines around, new effects land daily, and the editing tools are deeper than they look. Cons: the free version nudges you toward a subscription for premium filters, and heavy AR effects can heat up older phones. Best for selfie lovers and social-media creators who want trending looks without a separate editor.
