When an app's revenue declines, the cause may sit in monetization, retention, conversion, technical performance, or a combination of these areas. The companies below cover different parts of that recovery process, from mobile app audits and engineering work to subscription optimization, paywall testing, retention, and growth strategy.
Gilzor focuses on recovering underperforming mobile applications by connecting business symptoms such as declining revenue, retention, ratings, and conversion with product and technical problems. Its Mobile App Audit covers iOS and Android applications and examines store performance, critical user flows, crashes, SDKs, dependencies, architecture, performance, and release risks. The resulting recovery roadmap prioritizes issues by business impact and includes effort estimates and quick wins. Gilzor also handles implementation through mobile development, QA, maintenance, and product engineering. Its published case studies include a flight-tracking subscription app that achieved substantial revenue growth after an architecture rebuild and broader product recovery work.
