At Treeapp, we believe that small daily actions can add up to big change. That’s why we built an app that makes planting trees as simple as tapping your phone. Supporting reforestation is one powerful way to live more sustainably, but it’s not the only way.

With that in mind, we’ve rounded up the 5 best green apps for 2025 that can help you live more sustainably (And yes, we’re proud to put Treeapp at the very top of the list!)

1. Treeapp - plant trees every day 🌳 (our top pick)

Of course, we have to start with Treeapp. With our app, you can support tree planting daily, for FREE across our reforestation sites in 14 countries all around the world.

2. Too Good To Go - fighting food waste 🍴

Every year, over one-third of food goes to waste globally. Too Good To Go helps fight this by connecting users with local cafes, bakeries and restaurants offering surplus food at the end of the day. You get delicious meals at a fraction of the price, while perfectly good food stays out of the bin!

3. Olio - share more, waste less ♻️

Olio is a community sharing app that helps you give away (or collect) food and household items that might otherwise go to waste. It’s a fantastic way to reduce waste, save resources, and connect with people in your local area.

4. Ecosia - The search engine that plants trees 🔎

We love any app that plants trees alongside us! Ecosia is a search engine that uses its ad revenue to fund global reforestation projects. By using Ecosia, your web searches help fund global reforestation projects, tree planting initiatives, and environmental conservation efforts.  It’s a simple swap that turns everyday searches into climate action.

5. Liftshare - best for greener travel 🚘

Liftshare helps people heading in the same direction connect and share car journeys. It’s a simple way to cut travel costs, reduce carbon emissions, and make commuting more sustainable. By turning empty car seats into shared trips, you’re making a positive impact on both your wallet and the planet.
