Sixteenths: Construction Calc is a specialized utility for construction professionals that performs math using feet, inches, and fractions on iOS.
The App DNA
What makes this app unique?
The app removes the cognitive friction and rounding errors inherent in using standard decimal-based phone calculators for jobsite measurements.
For Construction professionals and serious DIYers who require precise, job-specific math for framing, roofing, and concrete work.
What does it look like?
Key features
Calculates using feet, inches, and fractions as primary inputs without converting to floating-point decimals.
Ten specialized modes for construction tasks including roof pitch, stairs, hip and jacks, and concrete volume.
Automatically saves calculation history with exact values for later recall and naming.
Operates entirely without network connectivity or account sign-in requirements.
How much does it cost?
The freemium model uses a ten-calculation limit to demonstrate utility before gating advanced solvers and history behind a subscription or lifetime license.

Key takeaways for Sixteenths: Construction Calc
Where is it heading?
The construction utility market is consolidating around tools that offer both precision and offline reliability. Sixteenths is well-positioned to defend its niche if it maintains its focus on exact fraction math, but it must address the subscription friction to scale beyond its current professional base.
- The offline-first design removes connectivity dependencies, which creates a durable retention loop for jobsite environments where cloud-dependent rivals fail.
- The current maintenance-only release cadence suggests a stable product, but limits the ability to respond to emerging competitor feature sets.
The SWOT
- Exact fraction math prevents rounding errors in cut lists
- Offline-first architecture ensures jobsite reliability in low-coverage areas
- Localized pricing could capture market share in regions where trade-specific calculators remain expensive or cloud-dependent
Next best moves
Ship a 'Pro-Lite' tier because the current $4.99/month gate is a high barrier for casual DIYers → increase conversion volume
The counter-intuitive read
The app's maintenance-mode cadence is a strength, not a weakness…
Read the full takeBottom line
Sixteenths secures professional trust through exact fraction math, but the current subscription-only gate for history recall limits the funnel to high-frequency users. A lower-cost entry point would unlock the casual DIY segment without eroding the professional-grade brand.
