Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

Structural Engineering Calculator delivers 59 AISC and ACI structural formulas with instant results, demand/capacity checks, a built-in AISC section database, and material references — all in one app. Whether you’re on site, in the office, or reviewing drawings, every calculation you need is in your pocket.
59 STRUCTURAL FORMULAS
COLUMNS
Critical Ratio (Cc), Effective Length Factor (K), Slenderness Ratio (KL/r), Allowable Compressive Stress (Sr less than Cc), Allowable Compressive Stress (Sr greater than Cc), Safety Factor, Maximum Axial Load.
BEAMS
Shear Capacity of Flexural Members, Allowable Bending Stress (Compact and Noncompact), Moment Gradient Factor (Cb), Allowable Flange Bending Stress, Plastic Moment (Mp), Lateral Unbraced Lengths (Lp and Lr), Limiting Buckling Moment (Mr), Nominal Moment (Mn), Critical Elastic Moment (Mcr), Allowable Shear Stress, Beam Deflection for UDL and Point Load.
BASE PLATES
Base Plate Area, Plate Thickness, Bearing Pressure, Flange and Web Thickness, Plate Dimensions N and B.
COMPOSITE BEAMS
Horizontal Shear for Concrete and Steel, Number of Shear Connectors, Transformed Section Properties, Modular Ratio, Elastic Neutral Axis.
CONNECTIONS
Allowable Shear with Tension Field Action, Allowable Bearing Stress for Rollers and Rockers, Axial Stress for Concentrated Loads, Allowable Bearing Stress on Fasteners, Number of Shear Connectors, Total Horizontal Shear.
AISC CODE REFERENCES
Every formula links directly to AISC and ACI clauses — AISC 360-16, AISC ASD 9th Edition, ACI 318-19, and AISC Design Guide 3.
PASS / FAIL CHECK
Instant visual adequacy check with demand/capacity ratio — green for PASS, red for FAIL.
AISC SECTION PICKER
Browse W-shapes (AISC 15th Edition) and auto-fill section properties instantly.
REFERENCE TAB
Built-in library with W-sections (W4–W44), ASTM materials (A36, A992, A572, A500, A325, A490, F1554), weld electrodes, concrete grades, and codes.
USCS & SI UNITS
Switch anytime between USCS (in, kip, ksi) and SI (mm, MPa) with automatic conversion.
All section and material data included. Supports both USCS and SI units. Compatible with iPhone and iPad. One-time purchase — no subscriptions.
References: AISC Steel Construction Manual 15th Edition, AISC 360-16, AISC ASD 9th Edition, ACI 318-19, AISC Design Guide 3.
What’s new
Release notes for the latest version, as written by the developer.
Major Update
AISC-referenced formulas with clear PASS/FAIL demand/capacity checks, built-in W-shape section selector (W4×13 to W44×335), full support for USCS (in, kip) and SI (mm, MPa) units, calculation history, PDF report export, and categorized formulas for Columns, Beams, Connections, Base Plates, and Composite.
