This app Calculate Pump hydraulic Power, Pump shaft power and Pump Motor Power
For a "pump flow calculator" search, Pump Power matches intent instantly: its first screenshot's yellow "PUMP POWER CALCULATOR" header sits directly above a "Flow Rate" field in m3/hr. Free Hydraulic Calculator shows more depth across three worked calculators, including "FORCE 8000 lbs" and a motor page ending in hp, but never surfaces its pump screen, and the iOS-style Back/Reset bars read as unfamiliar chrome on a Play listing. Neither side carries a visible trust cue or an outcome caption, so this contest is decided on keyword relevance versus demonstrated range.

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.

Value Proposition
B leadsFree Hydraulic Calculator's hero promises broad "Hydraulic Calculator" coverage, but none of the four screenshots show the pump page a pump flow searcher wants.
Pump Power's first screenshot opens on a yellow "PUMP POWER CALCULATOR" banner with "Flow Rate" in m3/hr as the very first input.
Clarity
A leadsThree distinct tools shown with filled numbers: bore 4 in yielding "FORCE 8000 lbs", motor power 19 hp, and torque in inlbs, ftlbs and Nm.
Pump Power repeats one five-field form across three screenshots, and the fourth shows a "Let'sFab" drawer with Books and Channel instead of functionality.
Emotional Hook
TiedFree Hydraulic Calculator shows only input grids labelled "PISTON/ BORE DIAMETER" and Copy buttons, with no user, scene, or outcome statement anywhere.
Pump Power's shots keep the device status bar and an ad banner in frame; captions name fields like "Specific Gravity", never a result or relief.
Trust Signals
TiedOnly a "Zenithic Innovations Inc." logo on the hero; the "There are no ads in this App" claim stays in the description, unseen by browsers.
Pump Power shows no counts, endorsements or badges; the drawer's "Website" and "Our Books" rows are self-referential brand links.
Reviews of Free Hydraulic Calculator cluster heavily around the paid unlock, with several reviewers reporting the calculators stay locked until purchase, plus a smaller set reporting ANRs or the app not working; the positive side describes it as a quick, handy reference for on-the-job questions. Pump Power collects recurring mentions of ads and a specific unit error where pump flow is labelled in cubic metres per hour instead of litres per hour. Praise for Pump Power is concentrated on the pump calculation itself being useful, while praise for Free Hydraulic Calculator is about fast answers and a usable interface.

Pump calculation seen as useful
HighFree Hydraulic Calculator positions itself as a breadth play, one circuit-wide toolkit covering cylinders, pumps, lines and orifices for hydraulic system work, with "no ads" as its trust signal. Pump Power positions itself as a single-answer instrument, naming the exact chain a searcher wants sized: "hydraulic power, Shaft power, Motor Power" for centrifugal pumps. Against the query "pump flow calculator", the mismatch is that the pump-flow capability exists in both listings but only one of them says the word "pump" where a searcher looks first.
App A
Positioning
Broad hydraulic circuit toolkit
Target audience
Engineers and technicians designing or servicing hydraulic circuits
Value promise
One ad-free app covering every routine hydraulic circuit calculation
Tone
feature-focused, matter-of-fact, technically literate
App B

Single-purpose pump sizing calculator
Target audience
Mechanical, chemical, electrical and instrumentation engineers sizing pumps
Value promise
Calculate pump hydraulic, shaft and motor power quickly from five inputs
Tone
plain, task-focused, engineering shorthand
Gap
Free Hydraulic Calculator leads with coverage of a whole discipline, naming "hydraulic circuits" and burying pump work as one of four calculation families, while Pump Power leads with a single named machine and its three power stages, putting "Pump" in the first word of the title, the subtitle and nearly every description line.
Opportunity
A searcher typing "pump flow calculator" is mid-task on one component but usually needs line velocity, pressure drop and orifice sizing next, which gives Free Hydraulic Calculator the opening to be framed as the app you keep open after the pump number lands.
Risk
Neither the title nor the subtitle of Free Hydraulic Calculator contains the word "pump", so a pump-flow searcher scanning a results list has no on-listing confirmation that the app solves their exact question, and the description also front-loads the paid-version limits ("limited to 1" or 25mm line diameters"), which reads as a restriction before any benefit has landed.
Strategic advantage
Free Hydraulic Calculator can own the one-app-per-circuit claim for fluid power technicians who otherwise install a separate calculator per component, reinforced by the ad-free stance that matters to people using the app on a shop floor between measurements.
Missed opportunity
Neither listing speaks to field troubleshooting, the moment an engineer is at a running machine trying to work out why measured flow or pressure does not match spec, as opposed to designing on paper. Both also stay silent on unit-mixing confidence, despite metric and imperial handling being a live source of costly errors in this work.

Pump Power
Slight gap
On pump flow calculator, Pump Power holds position 7 while Free Hydraulic Calculator sits at 18, yet the listing fundamentals run the opposite way: Free Hydraulic Calculator leads on store presence and keyword optimisation, and the two are level on conversion. That rank gap reads as winnable rather than structural.
Why it wins
Free Hydraulic Calculator carries the stronger listing fundamentals and the wider demonstrated range, three worked calculators against a single pump chain, while Pump Power's reviews collect recurring ads mentions and a reported unit error where pump flow is labelled in cubic metres per hour. Pump Power's higher pump flow calculator position comes from naming the machine first, not from a deeper listing.
Biggest opportunity
Neither the title nor the short description of Free Hydraulic Calculator contains the word pump, so a pump flow calculator searcher scanning results gets no on-listing confirmation that the pump screen exists, even though the app already solves that calculation.
Next priority
Test a short description that fronts the pump work, for example "Pump flow calculator, cylinder force & line pressure drop tools" (63 characters), which keeps the breadth claim while matching what a pump flow calculator searcher reads first. The second test is a one-time demo of a locked calculator, the exact thing reviewers say they want before paying.
