visible word pool · 5 words
title 6/30 chars · subtitle 26/30 chars
App Store search indexes the title and subtitle together with the hidden 100-character keyword field as one combined pool: any phrase assembled from those words can rank. These are the words of Qastle's pool that are public — the keyword field is not exposed by any API.

Awful Support / Fraud
Promos are not real. Bitcoin 2026 promo was a lie, no info whatsoever. Took my money without recourse and now I will not be using their platform, which tbh feels basic and not feature rich like other more secure wallets I’m aware of.
