Top 5 Sustainable Apps You Should Download in 2025
Sustainability is becoming part of everyday life, and apps are making it easier to take small but meaningful steps. From finding pre-loved bargains to cutting food waste, these tools can help people live a little greener in 2025.
1. Ganddee
Ganddee is like a digital treasure map for second-hand shopping. It helps you discover charity shops, thrift markets, vintage pop-ups, and car boot sales nearby.
You can save your favourite spots, check reviews, and even unlock exclusive discounts. Some users also join Ganddee events or online groups to meet like-minded bargain hunters. If you love vintage finds or want to shop more sustainably, Ganddee is a great place to start.
2. Good On You
Fast fashion is a big challenge, and transparency is often lacking. Good On You tackles this by rating clothing brands on their environmental impact, labour conditions, and animal welfare.
Type in a brand name and the app will give you a score along with key details about its practices. For many, it’s a quick way to compare options and avoid greenwashing when making fashion choices.
3. Earth Hero
Think of Earth Hero as a climate coach in your pocket. The app helps you calculate your carbon footprint, set goals to reduce it, and track your progress over time.
It also offers practical tips across travel, shopping, food, and lifestyle. By breaking down climate action into manageable steps, Earth Hero makes it easier to see how daily habits add up.
4. Too Good To Go
Every day, restaurants, cafes, and shops are left with unsold food that would otherwise go to waste. Too Good To Go connects users with that surplus food at a reduced price.
The catch? You don’t know exactly what will be in your bag until you collect it, usually at the end of the business day. For businesses, it cuts down on waste. For customers, it’s a chance to save money and enjoy a surprise meal.
5. Olio
Olio is all about sharing. Users list unwanted food, household items, or even skills, and neighbours can claim them for free.
It works like a local marketplace, but the focus is on reducing waste and building stronger community connections. Whether you have extra groceries or unused household items, Olio helps ensure they find a new home instead of going in the bin.
The Big Picture
On their own, no single app will solve climate change. But tools like Ganddee, Good On You, Earth Hero, Too Good To Go, and Olio show how technology can support small, practical steps toward sustainability.
From thrifting and rating fashion brands to cutting food waste and sharing with neighbours, these apps give anyone the chance to start living more sustainably — one download at a time.
