CST LINE About
A Los Angeles company for practical home apps.
Our core work is offline-first household utilities. We also keep a consulting layer for home space planning, plus careful publishing support.
CST LINE INTERIORS LLC is based at 631 S Cochran Ave, Los Angeles, CA 90036, United States. Our public website exists so partners, users, and reviewers can verify who we are, how to reach us, and how our mobile products handle data.
Core focus
We build and publish practical home utility apps. Our current product, Home Energy Bill Tracker, helps households log electricity, gas, and water bills and review rates offline—without accounts or cloud sync in V1.0.
Consulting layer
Alongside products, we offer home space planning consulting: layout priorities, residential coordination notes, and finish direction frameworks. This is advisory—not construction contracting, and not a portfolio of unverified project claims.
Support line
We can coordinate app listing materials and compliance pages. We do not promise approval, ranking, installs, or revenue.
What we do not claim
- We do not claim official partnership with Google, Meta, or utility companies
- We do not promise installs, revenue, or review outcomes
- We do not invent ratings, download counts, or client logos
