Key features
Calculates area, perimeter, and side lengths for right, isosceles, and scalene triangles. Core utility function that drives daily active usage — expands ad-impression inventory.
Computes Pitch Circle Diameter and chord dimensions for engineering and fabrication tasks. Specialized tool for professional users — potential anchor for Lifetime Premium conversion.
Provides solutions for circles, squares, rectangles, pentagons, hexagons, and octagons. Broadens utility for students and DIY users — increases session frequency.
In-app purchase option for full access to all calculation tools. Paid-gate — direct conversion lever for users seeking ad-free or full-feature access.
How much does it cost?
The freemium model utilizes a single Lifetime Premium purchase to gate advanced features and remove friction.
Velocity
Dormant developmentperformancemonetizationShow more...
Angle Finder - Trig Calculator has been inactive for 270 days, falling well outside the threshold for active development. The latest release focused on minor technical adjustments, including in-app purchase stability and measurement accuracy. Given the lack of updates for nearly nine months, the app is currently in a zombie state with no evidence of ongoing maintenance or feature expansion.

Key takeaways for Angle Finder - Trig Calculator
Where is it heading?
The engineering utility market is consolidating around apps with frequent, verified update cadences. Angle Finder - Trig Calculator's current trajectory is declining, as the lack of development velocity and broken monetization logic prevent it from competing with active rivals.
- The nine-month release gap suggests the app is in maintenance mode, which erodes professional user trust in calculation accuracy.
- Persistent payment restoration failures drive negative sentiment, which compounds the risk of refund requests and store-level visibility penalties.
The SWOT
- PCD and chord calculation tools provide a specific utility barrier for engineering and fabrication segments
- Implementing a transparent subscription tier could stabilize revenue compared to the current single-purchase gate
