User Reviews

Time Master + Billing is highly regarded for its long track record, deep time-tracking and invoicing features, and cross-device use. However, recurring issues include startup crashes on newer OS versions, perceived stagnation with infrequent updates and an aging UI, and weak support options. It also lacks collaboration and centralized syncing for teams. Overall, it remains powerful for individuals and small businesses, but stability and ongoing support are common concerns.

Pros

Longstanding reliability with years of use and generally stable operation.
Deep, flexible feature set for time tracking, invoicing, payments, and reports.
Easy to use despite its depth and breadth of features.
Cross-device syncing and data backups (e.g., Dropbox).
Invoicing and time-sheet capabilities with straightforward reporting/export options.

Cons

Startup crashes on recent OS versions (e.g., iPadOS 18.7.2 / iOS 17.7.2) indicating stability concerns.
Perceived stagnation: outdated UI and a lack of ongoing updates, including limited Apple ecosystem modernization (no OS X/Apple Watch updates).
Weak or broken support/contact options (support link 404, difficulty reaching the developer).
Lack of collaboration features and centralized syncing for teams or multiple users.

I’ve been using this for my whole career to track time. While not perfect, it does 95% of what I need and does those things well. I see app was just updated - developer continues to work on it (and hope he continues to do so!)
