What the Data Can. And Cannot: Show
The release and rating fields are useful screening signals. They are not evidence about a developer's motives, active users, revenue, or current search demand.
Release Recency
The latest release date in CloneChart's record is 2018-12-20. Verify the live App Store listing before relying on it.
Aggregate Rating
The stored listing reports 4.9 stars from 2,791 ratings. That total is cumulative, not a measure of recent activity.
Listing Context
The record identifies Health & Fitness as the category and Slumber Studios, LLC as the developer. It does not prove present availability in every storefront.
Maintenance Context Is Unknown
Public listing metadata does not explain release decisions. CloneChart does not infer abandonment, a broken app, or an addressable audience from release age alone.
What a Builder Can Evaluate Next
Available Signals
