Swimming Pool Calculator captions all four screenshots and puts a calculator grid covering Chlorine through Langelier Saturation Index directly in front of the searcher, so its scope reads instantly. Pool-Calculator's underwater hero, "Keep your Water Crystal Clear!", is the more emotive opening frame, but the three screens after it carry no captions and ask the searcher to decode FC, TA and CYA columns unaided. Neither listing shows a rating, download count or testimonial, so trust is decided by a single support screen.

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
A leadsEvery screenshot carries a benefit caption; "Calculate quickly the exact amount of products to add" answers the pool calculator query head on.
Pool-Calculator's hero states an outcome, "Keep your Water Crystal Clear!", but the three screenshots after it carry no caption text at all.
Clarity
A leadsThe PARAMETER CALCULATORS grid names Chlorine, pH, Alkalinity, Cyanuric Acid and Langelier Saturation Index; the second screenshot shows a numbered vacuum procedure.
The FC, TA and CYA range table and the bleach dosing result are concrete, but slot one is a logo splash and slot three a setup form.
Emotional Hook
B leadsCaptions name capabilities and steps; the 14 item "VACUUM THE POOL" list reads as chores rather than the payoff of swimmable water.
An underwater pool photograph behind "Keep your Water Crystal Clear!" pairs outcome copy with aspirational imagery, though no pool owner appears in frame.
Trust Signals
A leadsThe CONSULTS screen surfaces WhatsApp support and a visible contact address, but no ratings, install counts or testimonials appear in any screenshot.
No badges, counts or testimonials across the four screenshots; the review request sits in description text where browsing users will not see it.
Swimming Pool Calculator draws consistent praise for its personalised advisory through premium WhatsApp consultations and for being easy to learn, while its recurring complaints centre on ads and on core water-testing being behind payment. Pool-Calculator is valued for telling owners exactly which off-the-shelf chemical to add and how much, but reviews repeatedly raise the account requirement, settings and target levels that do not persist, and dosing figures that some owners consider far too large. Both listings share the same underlying job, with Swimming Pool Calculator carrying more monetisation friction and Pool-Calculator more reliability and data-persistence friction.

LowSwimming Pool Calculator positions as a whole-pool maintenance manager that promises total control of the water and cheap fixes when it turns green or cloudy, while Pool-Calculator positions as a chemistry dosing engine that tells an owner "exactly how much of each chemical to add" and enumerates FCl, pH, TA, CH, CYA, salt, borate and CSI. The mismatch is that the searcher's query word, "calculator", is claimed in the title on one side and evidenced line by line in the body on the other. Both target the same owner, but one sells management and remediation, the other sells arithmetic precision.

Pool and hot tub owners testing water themselves
Value promise
Exact chemical doses for balanced water without charts or formulas

feature-focused, practical, test-kit literate
Gap
Swimming Pool Calculator leads with maintenance management and problem rescue ("the water turning green, cloudy"), while Pool-Calculator leads with named chemistry math ("Chlorine (FCl)", "Calcium saturation index (CSI, similar to LSI)") delivered as an explicit calculator toolkit.
Opportunity
Because Pool-Calculator stops at the dose and never says what to do when the water has already gone wrong, Swimming Pool Calculator can own the remediation moment: the owner who is not balancing numbers but staring at green water this weekend.
Risk
The title of Swimming Pool Calculator promises a calculator but the short description says "Manage your Swimming Pool" and the body names only "chlorine level, pH, etc.", so a searcher comparing it against an enumerated chemical list reads the calculator claim as unevidenced, which costs installs at exactly the moment of choice.
Strategic advantage
The pairing of a fix with its cost ("the fastest and cheapest solutions to any problem") targets a buying motive Pool-Calculator never addresses: the owner deciding whether to buy chemicals or call a service, where money, not accuracy, drives the decision.
Missed opportunity
Neither listing speaks to the owner who inherited a pool and has never tested water, nor answers the question that actually ends the session, whether the water is safe to swim in today. Both frame the job as dosing or upkeep rather than a go/no-go verdict for a family about to get in.

Slight gap
Swimming Pool Calculator at rank 6 and Pool-Calculator at rank 1 are separated by far less than their pool calculator positions suggest, with Swimming Pool Calculator ahead on keyword fit, screenshot clarity and review sentiment while Pool-Calculator holds a dominant positioning read. The deciding factor is evidence: whichever listing makes the calculator claim provable at a glance takes the keyword.
Why it wins
Pool-Calculator's rank 1 rests on a description that enumerates FCl, pH, TA, CH, CYA, salt, borate and CSI, so the arithmetic promise is proven line by line, while Swimming Pool Calculator carries the query term in its title and backs it with captioned screenshots and a calculator grid running from Chlorine to the Langelier Saturation Index. Neither side shows a rating or download count, so the trust gap that would normally settle a pool calculator race is unclaimed by both.
Biggest opportunity
The title already carries pool calculator exactly, so the gain is conversion rather than coverage: the short description "Manage your Swimming Pool with the Ideal Maintenance. Drive your Pool." sells management where the searcher came for arithmetic, leaving the strongest asset, the captioned parameter grid, undersold at the moment of choice.
Next priority
The remaining test is whether a short description that names the math and the payoff together, such as "Pool calculator: chlorine, pH, TA, CYA dosing for clear water" (60 characters), converts better than the current maintenance framing. A parallel test is making the basic water-test calculation free, since reviews repeatedly cite payment at the entry point as the friction, not the accuracy.
