Why users leave
The free diagnosis shows the top complaint. The full brief has every cluster, the build ideas and the buyers.
Support replies are slow or absent for days or weeks; users are redirected and left without fixes or follow-up.
“Initially when we had an issue - which is extremely common with this app - they were addressed pretty quickly but I am now having to wait days and even weeks for even so much as a response.”

How to read this
Sources: the product's public listing and reviews, its published price, and public forum threads. Revenue is an estimate unless marked verified by the founder; the formula and its inputs are on the full x-ray. Complaints are grouped by a language model and each quote is a verbatim excerpt, linked to the original review. Build difficulty is a model's reading of the listing and the complaints, not a measurement. Figures are a snapshot of Oct 30, 2026. Corrections: corrections.
