AppsNation's case study page documents the design and build of Boujee Beachin', a React Native app (with Node.js, MongoDB, AWS, and Stripe/G Pay) for discovering premium beach experiences, with reservations, reviews, and fashion recommendations. The page describes design goals, wireframes, user testing feedback, and a persona, but states no business results or time period. The engagement outcome is a finished app design, and any marketing or SEO results are not attributable from this page.

Reviews: Google 5 from 13 reviews. Ratings never count as evidence for this question.
Positions 11 to 12: the same breakdown is on each agency's profile, linked from the table above, and in the machine-readable version below.
A claim counts as backend and API evidence when a source on file names a backend, REST or GraphQL API, cloud setup (Firebase, AWS, Azure) or an integration with another system (payments, CRM, EHR, ERP, hardware) the company built for an app, ideally with the client named.
In plain words: a case counts when it names mobile backend and API integration work and where it was published can be checked.
Ranked vendors have at least 1 claim on file that supports mobile backend and API integration under the published rubric, of which at least 1 comes from a source outside Vendar; the rest are listed unranked.
Weights: Evidence for this query 30 · Fit to this query 25 · Capability depth 15 · Reliability 10 · Transparency 10 · Reputation 5 · Market credibility 5. Penalties: Profile flagged for review -5 · Evidence not re-checked in 18 months -5 · No independent source on file -3 · Profile below decision-ready status -2.
Verified means Vendar confirmed the company, its service and its market on official sources and stamped the profile with the date. A participation status or a partner relationship does not make a profile verified.
Every date shown is a data date. A listing's updated date is the newest verification date among its ranked vendors and the evidence claims their ranks rest on; the same value appears in the page text, the structured data and the machine feed.
A position reflects documented work for the page's question, not the quality of an agency as such. Without a public case or a visible campaign the result of an agency's work cannot be known from outside. An agency with no public evidence is not worse: there is nothing to confirm it with, so it is listed below the ranking instead of being ranked low.
