Key takeaways for Coffee DTR Timer
Where is it heading?
The home roasting utility market is shifting toward integrated, sensor-linked logging that automates the DTR calculation process. Coffee DTR Timer remains a stable, manual alternative, but its lack of active development limits its long-term relevance for users seeking deeper roast analytics.
- The 363-day update gap confirms a maintenance-only posture, which prevents the app from competing with feature-rich, automated roasting platforms.
The SWOT
- Manual event-logging interface enables precise control over roast phases without requiring expensive hardware integration
- Export functionality for roast logs would allow users to analyze profiles in external spreadsheet software

Read the full takeSince the last report: The application remains in a static, maintenance-only state with no functional changes to the codebase or feature set. The only material updates are the inclusion of specific user review counts and refined SWOT terminology.
Bottom line
Coffee DTR Timer serves its core function as a manual timer, but the lack of development activity limits its ability to retain users against more automated roasting tools.
