Duct Size Calculator for HVAC Design Engineers
Ductulator - HVAC Duct Sizing captions every screenshot with an outcome line, "Size HVAC Ducts Instantly" and "Find Optimal Duct Dimensions", so the benefit lands before any tap. Easy Offset – Duct Calculator ships four uncaptioned frames: three grids of unlabelled duct diagrams and one Trigonometry Calculator screen, leaving the title to carry the whole pitch. Both listings surface no independent credibility cues, and the "4.8★ from 300+ Ratings" overlay reproduces store rating UI inside a screenshot.

Only the first 4 screenshots from each side are sent to the AI. These are what users see in App Store and Google Play search results, so they carry most of the conversion weight.

App B
Value Proposition
B leadsAll four Easy Offset – Duct Calculator screenshots carry zero overlay text; the offset-diagram grids never state speed, accuracy or on-site benefit.
Ductulator - HVAC Duct Sizing headlines "Size HVAC Ducts Instantly", "Built for HVAC Professionals" and "Find Optimal Duct Dimensions" across screenshots 1-3.
Clarity
B leadsEasy Offset – Duct Calculator's 4th screenshot labels "Trigonometry Calculator" with Angles/Sides fields, but screenshots 1-3 are unlabelled diagram grids under ROUND/RECTANGULAR tabs.
Ductulator - HVAC Duct Sizing shows the whole workflow: 5200 CFM input, "MAXIMUM FRICTION RATE 0.08", then a VALID DUCT SIZES list with FPM values.
Emotional Hook
B leadsEasy Offset – Duct Calculator's frames are raw UI on flat blue, maroon and grey backgrounds, with no worker, jobsite or relief-from-rework message.
"Instantly" and "No Subscriptions One-Time Purchase" carry speed and cost relief, but Ductulator - HVAC Duct Sizing shows no installer or jobsite imagery.
Trust Signals
TiedNo testimonials, install counts, certification badges or offline claims appear on any Easy Offset – Duct Calculator screenshot or in its short description.
Ductulator - HVAC Duct Sizing's "4.8★ from 300+ Ratings" overlay on screenshot 1 reproduces store rating UI inside artwork, which store guidelines disallow.
Reviews of Easy Offset – Duct Calculator center on the premium purchase flow: users describe repeated charges, an upgrade screen that only offers cancellation, and a purchase that did not carry over to a new phone, while the positive reviews say the calculations return correct answers when inputs are entered properly. Reviews of Ductulator - HVAC Duct Sizing split between recurring praise for speed and ease of use in the field and recurring requests for round duct sizing and a fuller feature set, with several users asking for refunds. Both listings show a mismatch between what buyers expect and what the paid version delivers.

MediumEasy Offset – Duct Calculator positions itself as a field fabrication geometry suite, leading with offsets, laterals and rolled tees for the person cutting metal, and framing the enemy as "trig formulas, multipliers, or guesswork". Ductulator - HVAC Duct Sizing positions itself as a desk-side design instrument, replacing "the duct sizing charts provided by top HVAC manufacturers" with friction-rate and velocity output for design engineers. Both listings answer the query "duct calculator" but solve different jobs: one shapes the fitting, the other sizes the duct, so the two listings barely compete on substance while competing directly on the search term.
App A
Positioning
Field fabrication layout suite
Target audience
Sheet metal workers, detailers and duct installers on site
Value promise
Solve offsets and laterals fast without trig formulas or guesswork
Tone
Trade-practical, outcome-focused, mildly reassuring
App B
Positioning
Engineering duct sizing instrument
Target audience
HVAC design engineers sizing and analysing duct systems
Value promise
Faster, more versatile substitute for manufacturer duct sizing charts
Tone
Technical, specification-led, matter-of-fact
Gap
Easy Offset – Duct Calculator leads with fitting geometry for the installer holding the tin, while Ductulator - HVAC Duct Sizing leads with airflow sizing math, "friction rate" and "velocity", for the engineer at the drawing.
Opportunity
Because the sizing side of the category speaks only to design engineers, Easy Offset – Duct Calculator can own the shop-and-site half of "duct calculator" outright by naming the trade roles and the exact cuts they need solved.
Risk
The listing never mentions CFM, friction rate or duct sizing at all, so searchers who type "duct calculator" meaning sizing find no signal and leave; separately, "Reliable" and "Improved accuracy" are asserted without any stated method or standard, while the competing listing cites its calculation basis, which can cost trust with detailers who verify the math before trusting a cut.
Strategic advantage
The named tool inventory, Rolled Tees, Rolled Nineties, Rectangular Laterals and the "OW/L Calculator", reads as a checklist of the exact problems a fabricator faces in a day, which converts installers whose buying motive is avoiding a mis-cut* rather than passing a design review.
Missed opportunity
Neither listing puts a cost on being wrong: no mention of wasted sheet, re-cuts or a second trip to the roof, which is the concrete stake behind both products. Neither claims dependable operation in a mechanical room or basement with no signal, an easy ownership angle for a jobsite tool.

Ductulator - HVAC Duct Sizing
Strong lead
Ductulator - HVAC Duct Sizing holds rank 1 on duct calculator while Easy Offset – Duct Calculator sits at 7, and the gap comes from listing strength rather than keyword fit, since Easy Offset – Duct Calculator actually reads as the better-optimised listing for the term. The rank is defensible on conversion craft, not on positioning depth.
Why it wins
Ductulator - HVAC Duct Sizing captions every screenshot with an outcome line, "Size HVAC Ducts Instantly", so a searcher understands the job before tapping, and its store presence facts are close to complete. Easy Offset – Duct Calculator ships four uncaptioned frames of unlabelled duct diagrams, leaving the title to carry the entire pitch.
Biggest opportunity
Easy Offset – Duct Calculator already names duct calculator in both title and short description and out-scores Ductulator - HVAC Duct Sizing on positioning strength, so the gain is no longer coverage but making the fabrication job, offsets and rolled tees for the person cutting metal, land in the first screenshot frame rather than in the title alone.
Next priority
Caption the existing four frames with the tool each one solves and state the calculation basis behind the "Reliable" claim, since reviewers of Easy Offset – Duct Calculator report paying twice with no visible entitlement or restore path. The remaining copy test is whether a job-named line like "Duct calculator for offsets, laterals & rolled tees. No trig." (57 chars) beats the current short description.
