Calcu-Logarithm is an educational utility for solving logarithmic equations and visualizing mathematical proofs on iOS.
The App DNA
What makes this app unique?
It removes the friction of manual logarithmic computation and proof-verification for students who need step-by-step transparency.
For Students and mathematics enthusiasts requiring advanced logarithmic calculation, proof, and visualization tools.
What does it look like?
Key features
Provides step-by-step digit-by-digit computation of log_10(x) based on the M.Goldberg algorithm.
Explains and illustrates the calculation of log_e(x) using Taylor series expansions.
Simulates a physical slide rule for multiplication and division operations.
How much does it cost?
Calcu-Logarithm is distributed as a free utility with no visible in-app purchases or subscription gates.
Velocity
Dormant developmentplatform expansionShow more...
Calcu-Logarithm has been inactive for 268 days, falling well outside the threshold for active development. The latest release served primarily to cross-promote a separate statistical application rather than introducing new functionality to the core product. Given the lack of updates for nearly nine months, the development momentum is classified as stagnant.

Key takeaways for Calcu-Logarithm
Where is it heading?
The Education category is increasingly consolidating around platforms that offer interactive, community-driven learning experiences. Calcu-Logarithm's static, proof-focused model remains stable for its niche audience, but the lack of updates since December 2025 leaves it vulnerable to more agile, feature-rich competitors.
- The nine-month development silence indicates a maintenance-only posture, which limits the app's ability to capture new segments in the competitive Education category.
The SWOT
- Specialized proof-based tools provide utility beyond standard calculators.
- Virtual slide rule offers a unique educational interface.
- Interactive problem-solving sets could transition the utility into an active learning platform.
