Wanted: Android developer to help with Gamified Recipe App for the Climate

Time: 5-8 hours a week (or more) | No pay until we earn enough or get funding

Fork Ranger's mission is to help millions of people switch to a healthy and sustainable diet with a gamified recipe app. We already have an iPhone version and now we're looking for an Android developer.


The Mission

The food system makes up 33% of all greenhouse gases and most of it comes from eating too much meat. Alongside fossil fuels, it’s one of the most destructive forces on the planet.

The simplest solution is to change our diet. We don’t have to become vegan, only to make meat a luxury product for the weekend. A lot of people are interested to eat more sustainably but don’t know where to start. That’s where Fork Ranger is going to help.

It all started when Frank found out about the huge impact of meat but was frustrated with most vegetarian recipes. They had unknown ingredients or weren't filling enough. So he created a book that explains the problem and gives ‘user-friendly’ recipes. It has helped hundreds of people to eat less meat and now we're turning this into a digital experience.

Through recipes and food we want to inspire people to be part of the solution for a better world. We want people to feel like they can make a difference when it comes to climate change. It’s about offering a new version of 'the good life' that is not centred around consumerism but a purposeful life.

What is Fork Ranger?

We are working towards our mission in three ways:

The app

We're working on a habit changing app with recipes to solve climate change. This tackles two tricky questions that people struggle with:

  1. What can I do about climate change?
  2. What’s for dinner?

The iPhone version of the Fork Ranger app is already live. Right now it gives daily insight into a sustainable food topic and users discover a new recipe, which is connected to it.

The app is built in SwiftUI and loads the content through JSON.

Next step: Android

The current version of the app is already our fourth design. We've tested a lot and have finally found something that works. People use the app on a daily basis and we've got really good retention rates.

An important source of our current growth is word-of-mouth. But that's a lot less effective when half the population can't download the app.

That's why we want to start building the Android version.


In the meantime, we also want to connect the app to our other offline products, make it more fun to share with friends, and encourage cooking.

We prefer working with small weekly updates instead of dragging it out over months.

About Us 

I hope that by now you’re excited about the idea. Time to tell you a little about ourselves so you know what you're getting into 😉

Frank and Mareike are the founders and get help from six awesome people who help us in their spare time.

Frank is a storyteller and dreamer who loves to translate complicated topics like climate change into inspiring designs and stories. He created the Fork Ranger book and then Mareike joined him to create the app.

Mareike makes sure everything stays on track. She has a keen eye for details and structuring messy ideas. She's also vegetarian since she's 14 because somebody told her 'you will never keep this up'.

Jordi, Joost and Kevin are our developer friends who built the current iPhone app.

About You

Besides the practical points that you either speak Dutch or English there are two main things we're looking for: 

1) Passionate about the mission
You don’t need to be a vegetarian but you should join for the right reasons: working on a solution for climate change.

2) Android developer
We're looking for someone who has built an app before and is excited to build user-friendly apps. 


The Job

  • Responsibility: Build the Android Fork Ranger app
  • Time commitment: around 5-8 hours a week
  • Salary: none (until we earn enough or get funding)
  • Location: Amsterdam, The Netherlands (remote is possible)

What’s in it for you?

We’ve been working on Fork Ranger for two years and made some good progress. If you’re looking for a thrilling side project to improve the world, this might be a good opportunity to step into something promising. 

In short, this is what we can offer:

  • A chance to make more impact than Elon Musk (changing diets can save a lot more CO2 than electric cars)
  • The joy and friendship of working in an ambitious team
  • Working in a startup that has the opportunity to inspire millions of people

What is a bad fit?

  • Prefer to work alone
  • Mainly looking for a technical challenge rather than excited about a great user experience

What is a good fit? 

  • Want to make the world a better place
  • Taking initiative and bringing in own ideas
  • Love for great UX
  • Works fast and thinks in solutions
