This app calculate Required Belt length for drive system
For a "belt length calculator" search, Belt length Calculator wins the exact-match promise and proves it on its fourth screenshot with a filled form returning "Required Length of Belt : 925.93 mm.", while Pulley & Belt Calculator never shows a computed result. Pulley & Belt Calculator counters with a far more legible tool inventory: the six labelled tiles on its first screenshot (Ratio, Belt Length, Belt Speed, Hp / Kw, RPM) plus caption headlines on every frame. Neither listing carries any trust cue or outcome imagery, so both stall at feature display.

Value Proposition
TiedPulley & Belt Calculator's opening caption "QUICK & EASY CALCUATOR" is generic, and belt length is one unproven tile among six.
Belt length Calculator opens on two unlabelled pulley diagrams, but its fourth screenshot delivers the searched answer: "925.93 mm."
Clarity
A leadsPulley & Belt Calculator's Selection Menu names every function as a tile: Ratio, Belt Length, Belt Speed, Hp / Kw, RPM.
Belt length Calculator's inputs read "P.C.D of Large Pulley" and "Center Distance": precise for engineers, but the lead screenshot carries no labels.
Emotional Hook
TiedAll four Pulley & Belt Calculator frames are phone mockups with capability captions like "CALCULATE BELT SPEED", no workshop or user context.
Belt length Calculator's frames are unedited captures showing status bar, battery, and a loan ad banner beneath the calculate button.
Trust Signals
TiedPulley & Belt Calculator's "Works offline" claim sits only in the description; no badge, download count, or engineering credential appears in any frame.
Belt length Calculator shows no badge or credibility cue; three of four frames instead carry a third-party personal-loan ad strip.
Reviews for Pulley & Belt Calculator repeatedly ask for imperial units, with several users saying the metric-only input blocks them, and a smaller group reports the app locking up or not reopening correctly. Praise for Pulley & Belt Calculator centres on a simple layout and on professional workshop use, including replacing pen-and-paper ratio maths. Belt length Calculator draws the same metric-only unit complaint in 2 of its 9 reviews, while its recurring praise is that the calculation results come out correct.

High"Pulley & Belt Calculator" positions itself as a multi-variable drive toolkit, packing ratio, RPM, belt length, belt speed and Hp/kW conversion into one workshop utility. "Belt length Calculator" takes the opposite stance: one calculation, named in the title, with "Open belt arrangement & Cross belt arrangement" as its only depth claim. The mismatch is breadth against exact-question match, and for a searcher typing the precise task, the narrower listing currently reads as the more literal answer.

Gap
"Pulley & Belt Calculator" leads with breadth, five drive calculations under a pulley-first title, while "Belt length Calculator" leads with a single named task and the open-versus-cross arrangement distinction that the broader listing never mentions.
Opportunity
Claiming belt-length depth, specifically both open and cross arrangements, would let "Pulley & Belt Calculator" match the narrow listing on the exact search intent while keeping the ratio, RPM and Hp/kW breadth as the reason to keep the app installed.
Risk
The title's first word is "Pulley" and the subtitle places belt length third in a list of five outputs, so a searcher on this exact task may read the listing as a general utility rather than the direct answer. A user who already knows they need a cross belt sees the arrangement type named only in the other listing, which reads as a coverage gap even if the calculation exists.
Strategic advantage
Breadth plus "Works offline" is a coherent on-site story: a mechanic in a workshop with no signal solves belt length, then driven RPM, then the kW rating of the motor without switching apps. That serves the repeat-use buyer rather than the one-answer visitor.
Missed opportunity
Neither listing closes the loop from a computed number to a purchasable part, translating the calculated length into a standard belt designation or the nearest stocked size. For a user whose real job is ordering the right belt, buy the correct belt is unclaimed ground in this category.

Far behind
"Belt length Calculator" sits at position 2 for belt length calculator on the strength of an exact-match title, but "Pulley & Belt Calculator" at position 3 is the stronger listing on presence, conversion and review sentiment. The gap between them is a wording problem, not a product one.
Why it wins
"Pulley & Belt Calculator" shows a legible six-tile inventory across Ratio, Belt Length, Belt Speed, Hp / Kw and RPM, and its reviews describe real workshop use replacing pen-and-paper ratio maths. "Belt length Calculator" rests on a single calculation whose only depth claim is Open belt arrangement & Cross belt arrangement.
Biggest opportunity
The short description of "Pulley & Belt Calculator" already carries belt length but places it third behind pulley ratio, so the clearest gain on belt length calculator is making the searched task the first thing read rather than the third.
Next priority
Test a short description that fronts the task and claims arrangement coverage, such as "Belt length calculator for open & cross drives, plus pulley ratio, RPM, speed." at 78 characters, which keeps full belt length calculator coverage while naming the open-versus-cross distinction that only "Belt length Calculator" currently states. Behind it, an inches unit toggle is the most repeated request across reviews of "Pulley & Belt Calculator" and is unanswered by "Belt length Calculator" too.
