Delay Calc is a specialized BPM-to-time calculator for musicians on iOS, providing millisecond and hertz conversions for audio effects.
The App DNA
What makes this app unique?
The app removes the cognitive friction of manual tempo-to-delay math during studio sessions, though the lack of tap tempo forces a manual entry bottleneck.
For Musicians and recording engineers requiring precise timing calculations for audio effects.
What does it look like?
Key features
Converts BPM into rhythmic delay times in milliseconds.
Calculates frequency values for modulation effects.
Applies musical note values to BPM calculations.
How much does it cost?
Delay Calc operates as a free, ad-free utility with no current monetization.
Velocity
Dormant developmentopaqueShow more...
Development has ceased, with no updates or feature releases in over eight years. The app remains in a zombie state, as the last recorded version was shipped 2,926 days ago. There is no evidence of ongoing maintenance or operational activity.

Competitive landscape for Delay Calc
How's the Music market?
Delay Calc maintains a niche position as a free, single-purpose utility with a 4.5-star rating. The lack of updates since 2018 suggests a maintenance-mode posture that limits its ability to compete with modern, feature-rich audio tools.

The Analyst's Read
Key takeaways for Delay Calc
Where is it heading?
The market for audio utilities is consolidating around integrated DAW tools that offer broader functionality than single-purpose calculators. Delay Calc remains stable for its core audience, but the lack of active development prevents it from capturing users who require tap tempo or sub-sixteenth note resolution.
- The eight-year update gap signals a maintenance-only posture, which leaves the tool vulnerable to feature-rich competitors that integrate directly into DAW workflows.
- The removal of advertisements improves the user experience for a utility tool, potentially increasing long-term retention among existing users.
The SWOT
- Focused utility design removes cognitive overhead
- Reliable calculation logic for triplet delays
- Tap tempo integration would reduce manual friction
Next best moves
Ship tap tempo input because it is the top-requested feature → increase workflow speed
