How's the Business market?
Time Master + Billing holds a #51 Paid rank in the Business category (CA) on iOS, while the Android version maintains a high-volume casual gaming presence. The disparity between the $9.99 upfront cost on iOS and the free-to-play model on Android signals a lack of unified cross-platform strategy.

Key takeaways for Time Master + Billing
Where is it heading?
The professional time-tracking market is consolidating around integrated workflow partners, leaving standalone utilities like Time Master exposed. Unless the app pivots to a unified cross-platform experience, it will continue to lose high-value consulting users to competitors that offer better desktop and browser-based integration.
- The lack of native cloud-sync forces manual data management, which increases churn risk as professional users migrate to integrated SaaS alternatives.
- The latest update added photo receipt cropping, showing active maintenance of the core billing utility for professional service providers.
The SWOT
- Multi-level billing hierarchy provides granular revenue tracking for attorneys.
- Developing a native desktop companion app would unlock B2B integration.
Next best moves
Ship native cloud-sync because the lack of multi-device data parity is a primary competitive disadvantage → increase retention.
