Digital Health / Nutrition & Preventive Care

Calcium Calculator App Development For Radiant Digital Health

Radiant Digital Health wanted a lightweight, clinician-informed tool that helps users keep track of their calcium intake and support bone health.

Client's Goal

Provide an easy, trustworthy calculator that helps consumers quickly evaluate their daily calcium intake.
Make the tool accessible from both the website and mobile devices so users can check intake anywhere.
Surface simple, evidence-based recommendations (age/gender/life-stage aware) and present results in a friendly, shareable format.
Enable Radiant’s content team to update messaging and calculation parameters without developer help.
Keep the tool fast, accessible, and privacy-respectful.

Challenges

The Challenge for Impala

Business Challenges

The calculator needed to feel medically credible while remaining simple enough for lay users — balance accuracy with clarity.
Radiant required a low-friction flow so users can complete the calculation quickly (high immediate value), not a long form.
The client wanted the tool to support future content and clinical updates without rework.

Technical Challenges

Implementing evidence-driven calculation logic (age, sex, life stage, serving sizes) and keeping it auditable.
Providing consistent behaviour across web browsers and mobile devices, including offline/slow-network resilience for mobile users.
Creating a lightweight admin surface (or CMS integration) so non-technical staff can update tips, thresholds, and copy.
Ensuring privacy (no unnecessary personal data collected) while allowing optional user accounts for tracking history.

Features

The Tools That Power You

Accurate, Versioned Calculation Engine

Evidence-based rules (age, sex, life stage) implemented in a versioned API so clinical updates are auditable.

Interaction Design & Flow Simplification

Designed a minimal input flow: essential demographic fields + quick food/serving inputs so the calculation completes in one session. (UI was implemented to match Radiant’s brand.)

Front-End Implementation (Web + Mobile)

Built the web calculator as a responsive single-page component that degrades gracefully on small screens.

Delivered a mobile experience via a PWA / companion mobile app (depending on deployment preference) to ensure consistent behaviour on iOS and Android.

Calculation API & Data Handling

Implemented a lightweight, versioned serverless API for the calculation logic so changes to rules won’t require front-end releases.

Optional user-account endpoints were provided to allow intake history saving; privacy-first defaults were enforced.

CMS & Content Management

Integrated an admin editable content module (or headless CMS) for editorial updates to recommendations, help tips and localized copy.
