Project Overview
Creating a digital platform for easier charitable giving
ESAAR was designed to make charitable giving more accessible by connecting the public with nonprofit organisations through one web and mobile platform. The app created a simpler way for users to choose a charity, donate items or funds, request support, and participate in volunteer activity. Centangle developed the platform experience around ease, clarity, and trust. The work covered digital identity, web presence, mobile application design, user flows, and supporting visual communication so the charity experience could feel simple, human, and easy to use.
The Mandate
Building a web and mobile charity platform from the ground up
The requirement was to create a digital platform that could support donation, request, volunteer, and organisation-related workflows through a simple app experience. ESAAR needed an identity and interface that could make giving feel approachable while helping users move through key actions with minimal friction. The platform needed to support the emotional nature of charitable giving while keeping the product flow practical. Users had to understand where to donate, how to request support, how volunteer tasks worked, and how nonprofit organisations could fit into the broader platform ecosystem.
The Environment
A social impact space where trust and simplicity matter
Donation platforms need to feel trustworthy, easy to understand, and fast to use. If the flow feels complicated, users may hesitate before completing a donation or request. ESAAR needed a digital experience that reduced confusion and helped users take action quickly. The platform also needed to work for multiple user groups, including donors, support seekers, volunteers, and organisations. This required a clear structure where different actions could sit together without making the experience feel crowded or difficult to navigate.
Our Role
Delivering identity, website, mobile app UI, and visual communication
Centangle worked on ESAAR’s digital identity, website, mobile application experience, and supporting visual assets. The project focused on shaping the user flow, designing key screens, developing the web presence, and creating a visual direction that made the platform feel simple, warm, and accessible. The work helped translate ESAAR’s giving concept into a structured digital product where users could donate, request help, volunteer, and interact with charitable organisations through one connected experience.
The Challenge
ESAAR needed to turn charitable giving into a simple digital experience
The core challenge was to create a platform that could bring donors, requesters, volunteers, and nonprofit organisations into one experience without making the journey feel overwhelming. Giving needed to feel easy, clear, and emotionally aligned with the purpose of the platform.
The project also had to be delivered under a tight timeline, which made clarity of flow, identity direction, and interface decisions especially important. The challenge was to create a complete digital direction quickly while keeping the experience simple enough for everyday users.
Multiple User Journeys
The platform had to support donors, requesters, volunteers, and organisations without making the experience complex.
Simple Donation Flow
Users needed a clear and fast way to donate, request items, and participate in charitable activity.
Trust-Led Experience
The platform needed to feel credible, human, and easy to use so users would feel comfortable taking action.
The Solution
A web and mobile charity platform built around simple giving and social impact
Centangle created ESAAR’s digital identity, website, and mobile app experience to support donation, request, volunteer, and organisation workflows in one platform.
