Timeboat is a time-logging service. A time-log is a record of how much time was spent on a certain task. With the rise of remote work, the need for rethinking how work is evaluated has arisen. This "evaluation method" is the biggest challenge of the remote work era. Time-logs are the most important information for evaluating work correctly, and Timeboat records them. ▼Features & Differences from Similar Apps▼ [Half is Schedule] Half the screen displays schedules and the other half displays logs, allowing you to compare actual time spent with the planned schedule. Schedules can be synced directly from existing calendar apps (iCloud calendar / Google calendar). [Action Sharing] You can share the actions you created, allowing other users to use the same actions. [Create Report / Invoice] Logs can be viewed by day, week, and month. A day's worth of log data can be downloaded as a daily report in .jpg or .pdf. Also you can create invoice for client with only one tap. ▼Privacy Policy▼ https://timeboat.app/privacy ▼Feedback▼ Please contact us on Twitter: @timeboat_app. We welcome requests, bug reports, etc.

Verdict
The clearest difference is price: TimeBoat at Free against AddCalc PRO's $0.99. TimeBoat also leads on update cadence (every 2 weeks vs every 6 weeks). AddCalc PRO's advantage is ads (none vs shown) and device support (3 vs 1). On in-app purchases and iOS requirement there is nothing between them.
