Belt Calculator: V-Belt Length is a professional utility for mechanical engineers and technicians to compute V-belt drive geometry on iOS.
The App DNA
What makes this app unique?
The app removes the need for manual engineering tables and internet connectivity, providing field technicians with immediate, precise results in industrial environments.
For Maintenance technicians, millwrights, HVAC technicians, and mechanical engineers requiring field-ready belt drive calculations.
What does it look like?
Key features
Computes exact belt length using pulley diameters and center distance inputs.
Provides 8 SAE and 8 metric presets for common pulley pairs.
Operates without internet connectivity or account requirements.
How much does it cost?
The $1.99 upfront model removes the need for account registration or ad-supported revenue streams, reinforcing the tool's professional utility.
Velocity
Maintenance developmentopaqueShow more...
The app maintains a maintenance cadence, shipping only two releases over the observed window with an average interval of approximately 11 weeks between updates. The latest release provided no functional changes, focusing exclusively on metadata and naming. Development appears limited to minor administrative adjustments rather than active feature expansion or performance optimization. The current release pattern suggests a stable, low-activity state.

Key takeaways for Belt Calculator: V-Belt Length
Where is it heading?
The utility market for industrial calculations is consolidating around free, browser-accessible tools. Belt Calculator: V-Belt Length remains stable due to its offline-first design, but the lack of feature updates will eventually force a pivot to maintain relevance against free alternatives.
- The latest release focuses only on metadata, indicating a maintenance-mode posture rather than active feature expansion.
- The absence of new features allows free web-based rivals to erode the app's value proposition for professional users.
The SWOT
- Offline-first architecture removes connectivity dependency
- Quick-pick presets reduce field calculation time
- Localized language support for non-English industrial markets
- Integration of belt-tensioning guides for HVAC technicians
Next best moves
Ship belt-tensioning guides because HVAC technicians report tensioning as a top field challenge → increase utility value
The counter-intuitive read
The $1.99 price point is an advantage, not a barrier…
Read the full takeBottom line
Belt Calculator: V-Belt Length provides a stable, offline utility for core drive calculations, but the lack of active development risks losing ground to free web-based tools. Expanding the feature set to include tensioning guides would unlock higher value for professional users.
