Case study: Picho

Picho is a 4-months project I did as my final as an intern at Apple Developer Academy @ILB. It summed up all I have learned throughout my time in the academy. I started with no knowledge about building an app, being directly involved in it and to loving the whole processes that happened behind the scene.

‘Health’ was chosen as the big idea when the project started. As we looked around us, we found that a number of direct family members and friends are struggling with cholesterol. So, it became our challenge.

Our solution to the challenge is to develop Picho.

“A native iOS App that eases healthy eating habit for people with cholesterol who find it hard to change to healthier eating habit by giving them personalised daily eating targets based on their current eating habit, educating about healthy eating and providing motivation.”

My roles: UX Researcher, Copywriter, Scrum Master

Project status: Refining concept & design, Released on AppStore


Throughout the development of this project, I gained both technical and soft skills.

1. The importance of clear and open communication.

2. Always do user testing and validate.

3. Set meeting goals and timer. Always have a note-taker and a time-keeper.

4. There is no ‘finished’ design. It is always improved.

5. Spend time determining the proper questions to ask.


As this project was carried out during pandemic and where social distancing is enforced, all of our work had to be done online. We used the following tools as our platform to collaborate with one another.

Figma — for design, prototype, & wire-framing

Google Form — for survey and data collection

Marvel — for user testing & usability testing

Miro — for brainstorming, ideation & ‘whiteboard’

Notion — for task list, research notes & timeline

Zoom — for daily discussions, meetings & interviews


In our investigation, we noticed three points that are predominant:

1. People are aware of their cholesterol, and want to control it.

2. People need to know their food intake.

3. People need help on how they can improve their eating habit.

We then build and develop Picho’s features by addressing these problems.

Desk research and survey were done to narrow down the real problem to be tackled in this challenge. Investigation was further supported by examining different perspective from experts for more insights.

Brainstorming of possible solutions and creation of user personas based on potential problems found during investigation.

Create user flow and user journey, wire-framing.

Comparative study with potential competitors.

Solution concepts got validated by conducting interview and user testing.

During the first phase of Picho’s development, we created 3 personas, Rahman, Mamat & Messi, specific to each solution concepts.

Initial personas specific to each solution concepts.

These were refined as the development and investigation progressed. And now, we have Fred as our user persona.


We came up with these solutions to answer the problems:

1. Provide people with a tool to help calculate their daily saturated fat and sugar intake to manage their cholesterol.

2. Help them keep track of your food intake, so they can maintain it.

3. Give recommendation on what to improve based on people’s current habit.

Picho is still far from perfect, but the journey we have taken to be here is something that we are proud of.

We’re working to add more food database as the current version is limited to only verified Indonesian food sources. We’re also looking to improve and refine the assistant feature on Picho as a side project.

Thank you very much for taking the time to get to know Picho and the team behind it!

Credit goes to my teammates who have worked hard to build Picho together. Give their LinkedIn a visit & get to know them too!
