ChainApp — mobile app landing page
We built a mobile app landing page for ChainApp: a first screen with App Store and Google Play buttons, product features, reviews, pricing plans and newsletter sign-up. It runs on Bootstrap and went live in three days.
Challenge
ChainApp is a mobile app. The client needed a one-page landing that briefly explains what the app does, shows pricing and reviews, and leads visitors to the App Store and Google Play buttons.
A mobile app landing page has one job: explain in a few seconds why the product is worth installing and take the visitor to an app store button. Anything that pulls people off that path, from long copy to extra clicks to a crowded first screen, ends up as lost installs.
People arrive on the same page with different questions. One just wants the gist and a download button, another compares plans first, a third looks for reviews. The page has to answer each of them and still stay short enough to take in at a glance.
There were three days for everything. Building a design system from scratch in that time is unrealistic, so the foundation had to be a proven set of components that quickly comes together into a coherent page and behaves the same in every browser.
An app's landing page is naturally opened on a phone, so the mobile version matters more than the desktop one here. Navigation, carousels and forms have to work under a thumb, and the page itself has to load quickly and stay still while scrolling.
Solution
We assembled a one-page landing on Bootstrap 5, whose ready-made grid and components let us fit into three days. Navigation in a fixed header jumps to the main sections, and the visitor's path runs from top to bottom: the product promise, features, trust, price and a newsletter.
The first screen offers two buttons with App Store and Google Play icons straight away. Below come feature cards, an about block with an invitation to try the product for free, a review carousel with ratings, three pricing plans and a newsletter form. Sign-in and registration open in a modal window, via Facebook, Google or email.
Technically it is a static HTML page on Bootstrap 5.1.3 and jQuery: reviews slide in Owl Carousel, sections animate in on scroll, Font Awesome supplies the icons and Roboto the type. Hosting is on Vercel, so the page is served from a CDN, and the layout does not shift while loading.
A first screen with store buttons
A headline and a short subheading say what the page is about, with two buttons carrying App Store and Google Play icons right next to them. On the right, an illustration of a phone in a hand makes it clear at a glance that this is a mobile app.
Feature cards
Four cards with icons are set aside for the product's key features, and each one has its own Read More link. The card format is easy to read on a phone: one idea per block and no wall of text across the whole screen.
An about block and a free trial
The About section breaks the product down into four short points and ends with a free trial button marked 'no credit card required'. That removes the main doubt before any subscription: paying for something you have not tried yet.
A review carousel with ratings
Reviews sit in a carousel, and each one shows a name, a date, a category and a rating out of five. Visitors can swipe through them with a finger, and the compact format keeps the page short however many reviews are added.
Three plans and a newsletter
Prices are laid out in three cards, from a standard plan to a premium one, each with its own feature list and purchase button. Below sits a newsletter form, so visitors who are not ready to install yet still have a way to stay in touch.
Sign-in in a modal window
The sign-in button in the header opens a modal window where visitors can log in with Facebook, Google or an email and password, register or reset a password. Nobody has to leave the page or lose the place where they stopped reading.
