Chemicals Updates App

The home dashboard of Chemicals Updates greets you with a bright blue header, a notification bell, and a clean split between two core sections — Chemicals and Polymers. Below those entry points sits a Top News feed with articles covering market developments, accompanied by images of shipping vessels and industrial processing plants. The overall structure is logical and consistent across every screen, with a persistent bottom navigation bar carrying four labeled tabs: Home, Prices, News, and Profile.

What the Pricing Screens Cover

Drilling into the Chemicals section opens a menu of distinct price categories:

• Booking Price
• International Market Prices
• Mumbai Market Price
• Opening Ports Price
• Producer Prices

Each category leads to searchable, filterable price cards. A card for Acetic Acid, for example, shows the current price alongside the previous figure and the numerical change — displayed in red for a drop. From any card you can tap through to a line graph tracing historical price movement from 2021 to 2024, with multiple color-coded trend lines plotted against a dated x-axis.

Design Strengths and a Notable Weakness

The app's visual language is consistent: a blue-and-orange palette runs through headers, buttons, and icons, with the hexagonal molecular logo echoing the chemistry theme throughout. Typography is clear, and the information hierarchy is easy to follow. However, the price trend charts rely entirely on color to differentiate between data lines, with no alternative data table or non-color indicator provided — a real gap for colorblind users or anyone using a screen reader. The accessibility documentation flags this as a critical issue, noting that price change indicators also depend on red coloring alone, without accompanying symbols or arrows.

The Sidebar and Subscription Layer

A left-sliding sidebar, accessible via the hamburger menu, holds account options including Contact Us, About Us, Directories, and Log Out. A subscription banner on the home screen — illustrated with two cartoon scientists working at a lab bench with colorful beakers — promotes the paid tier to the app's growing user base. The sidebar occupies roughly 70% of the screen width when open, overlaid on a darkened background.
