We build the ranking from public activity signals around mini apps.
Our overall "trend score". It's calculated by our own formula that combines Reach and Activity to estimate how hot an app is right now — we try to keep it as objective as possible.
An estimate of unique real users who engaged with the app's mentions/content (a proxy for overall exposure).
A measure of content + interactions around the app: posts/mentions plus engagement like likes, recasts, reactions, and replies.
