Number Line - Elementary math
By Simon Storz
Number Line - Elementary math is an educational tool for elementary students that maps numerical values to spatial positions on a number line.
The App DNA
What makes this app unique?
The app removes the cognitive friction of abstract arithmetic by providing a visual, interactive mental model for number scales.
For Elementary school children learning basic mathematics and mental number line representation.
What does it look like?
Key features
Interactive mapping of numerical values to spatial positions, establishing the app as a core learning utility.
Scalable number ranges from 10 to 100,000, extending utility across multiple grade levels.
Hardware-specific mode for identifying numbers from owl positions, driving adoption in tablet-based classrooms.
How much does it cost?
The $1.99 single purchase model provides full access to all modes without recurring fees, which appeals to parents seeking ad-free educational tools.
Velocity
Dormant developmentopaqueShow more...
Development has ceased, with no updates or feature releases in over 1,800 days. The app remains in a zombie state, as the last recorded version was shipped in August 2021. There is no evidence of ongoing maintenance or operational support for the platform.

The Analyst's Read
Key takeaways for Number Line - Elementary math
Where is it heading?
The educational app market is shifting toward subscription-based, adaptive learning platforms that provide continuous value. Number Line - Elementary math remains a stable, single-purpose tool, which secures its position for parents avoiding recurring costs but limits its long-term growth potential.
- The 50-month development freeze indicates a maintenance-only posture, which limits the app's ability to capture new market share in the Education category.
The SWOT
- Spatial mapping mechanism builds foundational arithmetic fluency.
- iPad-exclusive input mode supports B2B classroom expansion.
Next best moves
Audit hardware compatibility because the 5-year update gap risks breaking core functionality on newer iOS versions → maintain existing user base.
