Taximetrix

A specialized Android app for taxi operators. Day entries, expenses, recurring fees, fuel snapshots, premium unlock through Google Play Billing and a full backup/import/export round-trip — a practical, supporting business-operations build that demonstrates real Android execution and local persistence at Crovyx.

Taximetrix — Android day entries, expenses, recurring fees, fuel snapshots and backup
Day entry → expenses → recurring fees → fuel snapshots → backup/import/export. Native Android, local-first.
The product

Native Android for a real business workflow.

Taximetrix is a focused operational tool: a taxi driver opens it after a shift, enters earnings and expenses, manages recurring fees and fuel, and exports a backup. It looks small from the outside — and is a complete Android product with real persistence, billing and migration concerns on the inside.

  • Day-entry capture for shifts, earnings and expense lines.
  • Recurring fees and fuel snapshots with structured local storage.
  • Premium feature unlock via Google Play Billing, integrated into the app lifecycle.
  • Backup, import and export so a driver can move their data between devices.
Why it’s here

Supporting evidence, not just flagship demos.

Taximetrix sits in the portfolio as honest supporting evidence: Crovyx ships real Android apps end-to-end, not only flagship platforms. The same engineering discipline shows up in a single-purpose business tool with billing and backup, exactly as it does in the larger systems.

  • Native Android implementation with a clear domain model.
  • Real Google Play Billing integration, not a stub.
  • Proper data migration story — not “reinstall and lose everything”.
Capabilities demonstrated

What this app shows.

Android execution

Native Android delivery with structured local persistence around an explicit business domain — shifts, expenses, recurring fees, fuel.

Monetization

Google Play Billing integration with premium feature gating, lifecycle handling and a working purchase path through Google’s store.

Data ownership

Backup, import and export so user data is portable and survives device changes — a hard requirement for any serious operational tool.
