Mint Diagnostics was founded in the tech cluster of Cambridge with a mission to redefine how hormone data can be collected, monitored, analysed and used to improve human health and performance. Our track record developing wellbeing, fitness and healthcare apps meant that we were the right team of UX designers and app developers to help Mint from the very start.

Digital innovation in hormone monitoring & analysis

The Hormonix platform and lab service combines Mint Diagnostics biosensing technology with hormone measurement protocols and data interpretation to enable a precise and individualised approach to hormone monitoring and hormone analysis that is distinctive from other sport performance, wellbeing and healthcare apps on the market.

The Hormonix platform is used for health, wellness and performance management across elite sports, cancer diagnosis, employee wellbeing and IVF, where hormone monitoring and hormone analysis, through a non-invasive technique such as saliva sampling, is desirable.

User experience design for sport performance, health & wellness

As a user experience agency that specialises in diagnostic and healthcare apps we are always looking for an interesting challenge and we were thrilled to be asked by Mint to design the blueprint of the user experience for Hormonix. 

The user experience needed to target  many different platforms including mobile, web and desktop as well as a proprietary hardware device that is being developed for remote saliva sampling and hormone monitoring, measurement and analysis. 

Our app designers have worked closely with Mints digital product development team to refine the user experience of the service through iterative storyboarding, prototyping and testing, often responding to new innovation in technology and a rapidly evolving set of requirements.

The user experience design process included the creation of storyboards and UX prototypes that describe the different customer touch points of the app and service, from saliva sampling to hormone monitoring, collection logistics and hormone analysis.

Functional prototyping

Initially our app designers and software development team focused their efforts on mobile application development, connecting the app  (via bluetooth) with Mint Diagnostics proprietary sensing hardware for a Cortisol hormone monitoring programme that targeted the wellbeing of corporate employees. The app on-boarded the user,  guiding them through the saliva sampling and hormone monitoring routine whilst displaying key information and hormone analysis back to the user. 

We worked with Mint to develop a “concierge” style field test, where human scientists would carry out the lab tests, but users had access to a functional prototype. This allowed the digital product development team to fine tune the saliva sampling process, ensure compliance, implement hormone monitoring protocols and define how best to conduct hormone analysis and provide feedback.

User experience design for Estradiol hormone monitoring

In parallel, our app designers worked closely with Mint Diagnostics to create the user experience design for their Estradiol hormone monitoring technology. These programmes were aimed at two sets of users: female cancer patients and  female elite athletes. Identifying their Estradiol curve through regular testing, monitoring and hormone analysis, allowed patients to optimise their treatment, and athletes their athletic performance.

Our mobile app development team created a startup MVP of what would eventually grow to become the Hormonix platform. The MVP required both web application development, mobile app development and desktop software development to fulfil the requirements of the product vision.

The Hormonix platform

Hormonix has grown into a service, mobile app and web platform that can be tailored to the needs of different organisations that want to use hormone monitoring to measure Estradiol, Progesterone and Cortisol levels.

The service uses a suite of digital products developed to facilitate the regular, non-invasive monitoring of hormone levels to provide regular visibility of hormone data that is then analysed by a team of experts. 

Our user experience designers and app developers are working continuously with the Hormonix digital product development team to advance the platform, continually improving the saliva sampling process, adherence and logistics, as well as expanding the data tracking, visualisation and hormone analysis capabilities.


Mobile application development

The Hormonix mobile app supports a participant that is saliva sampling, it is easy-to-use and has been designed to reduce the chance of human error. The mobile app includes:

  • Scheduling and reminders to coordinate saliva sampling and collection protocols.
  • Easy to follow saliva sampling and collection guides including in-app sample barcode scanning to register and timestamp the samples.
  • Questionnaire to capture contextual data and symptoms.
  • Hormone analysis that includes data visualisation of symptoms alongside  hormone data.

React and React Native

We took the decision together with the Mint Diagnostic team to develop the Hormonix mobile and web application as a React and React Native App. React Native is a cross platform development solution for iOS, Android and the Web that has excellent performance and reduces the maintenance burden of software development, which means it can be a great solution for MVP startups. 

React Native is the most popular mobile application development framework on the market for delivering universal applications. It is a JavaScript framework that has been created and open-sourced by Facebook and is a popular choice amongst mobile app developers.

Web application development

The Hormonix web application supports organisations running a programme by enabling coordinators to: 

  • Design hormone monitoring studies
  • Add/manage participants
  • Monitor saliva sampling to ensure protocol adherence
  • Visualise synchronised symptom and hormone data to conduct hormone analysis and gain actionable insights

Amazon AWS

The Hormonix platform is hosted on Amazon Services (AWS). For backend development we have used a series of serverless technologies including Amazon Cognito, AWS AppSync, Amazon DynamoDB and AWS Lambda that helps create flexible, scalable, and reliable backend that is cost effective. Utilising a pay as you go model on the backend works well for MVP startups as it allows the backend app to auto-scale as a user demand changes.

Portable hormone diagnostics platform

Our app designers are helping Mint Diagnostics create their proprietary microfluid system which enables easy saliva sampling and hormone analysis with no tools or specialised laboratory equipment. Application development is continuing on the Hormonix platform to enable the regular monitoring of hormone levels via the remote collection of hormone data, providing the opportunity for hormone analysis across many different and diverse sectors, from remote IVF to elite sports performance in women's football.

Hormonix branding

As part of the digital product design process our app designers designed an appealing brand, logo and visual language that could work across multiple digital platforms and a wide range of touchpoints, including a plethora of devices and print.

English Institute of Sport

Working in partnership with Mint Diagnostics and the English Institute of Sport we developed an app for athlete monitoring - collecting data on female hormones in high frequency, in a non-invasive way, using saliva sampling rather than blood collected with needles.

The samples are collected and sent to the Hormonix lab service where they are processed and analysed in a time efficient manner, to allow the athlete, their coaches and support staff to act on the results from the hormone analysis, adapting the training schedule to improve athletic performance.

The Hormonix mobile application was developed to support athlete hormone monitoring so that training can be adapted to improve their athletic performance.

As well as being trialled by a number of elite athletes, from eight different sports (including female athletes training for the 2020 Tokyo Olympics), Hormonix was also successfully rolled out at Manchester City Women, providing detailed insight into players’ menstrual cycles and improving performance
