The app that plants trees, just by walking

Treekly offers an easier way to help fight climate change.

Trees every week, to help reduce your carbon footprint.

The Treekly Challenge is to maintain a walking habit of 5,000 steps per day. 


Complete the challenge 5 days out of 7 and you will earn one mangrove tree - planted on your behalf in our forest in Madagascar.

Turn your steps into climate action, and create livelihoods for people living in extreme poverty.


Download Treekly for free.

Take a positive step, today.

We automatically count your daily steps from your phone’s built-in pedometer or geo-location. Alternatively, you can connect via Apple Health or our Treekly Watch.

Watch your personalised Climate Impact score improve as you earn and plant more trees.

If you really want to make strides, upgrade to Treekly Plus, rewarding you with one tree every day you reach your 5000 steps. You will soon become Climate Positive.

Download the free app to count steps, challenge friends, and plant trees. 

Climate action, one tree at a time.

Walking is one of the easiest ways to get active, and we believe that nature gives us one of the most powerful tools for fighting climate change.


Trees are an incredible, natural intervention for capturing carbon from the atmosphere.

There is no single easy solution to climate change but planting millions of trees is a key part of it.

Your steps turn into carbon-capturing mangrove trees, and better still they create livelihoods for people living in extreme poverty by empowering them to restore and protect forests on a massive scale. 


How are you funding the free trees?

The majority of people use the app for free. When they earn trees by completing the Treekly Challenge (5000 steps, 5 days a week), these are sponsored by a third party. We carefully select only ethical, green partners to give them the valuable opportunity to sponsor the Treekly Challenge for 1 week at a time. This means the user's tree earned that week is presented as being sponsored by that partner. The app is designed such that their exposure is non-intrusive to the user yet effective for the sponsor. A win-win!
There's also the option to fund trees yourself if you (or your business) want to have even more of a positive climate impact. Trees earned by users as part of Treekly Plus or Treekly for Business, or by purchasing tree packs are funded by the subscription or one-off payment.

How are you calculating an average carbon footprint?

We know that calculating carbon emissions can be tricky. There's lots of things to consider, like whether you're counting just carbon or also 'carbon dioxide equivalent' (CO2e) gases like methane. In general, when we're talking about your carbon footprint, wemean all of the CO2e emitted by day-to-day activities. This adds up things like diet, car usage, travel, heating your home, and buying things. There are numerous comprehensive research papers that have their own calculations, and the variation in results reveals how tough it is to come up with an agreed average footprint, because we all live such different lifestyles. As a mid-range figure plus an additional allowance, we believe that 12 tonnes per year is a fair estimate for the average adult in UK.

How do you ensure the trees are protected?

We asked our tree planting partner the same question during the process for making our decision on who to partner with. They have planted over 650 million trees since 2005. That's one every second! To ensure the trees planted are permanent and sustainable, they: - hire locals to plant the trees. In this way, extreme poverty is alleviated within the impacted community, whose members now have an economic incentive to ensure the wellbeing of the restoration project. They also have a sense of “ownership” over the trees and restored forest and they protect it with great care. - hire forest guards as part of the labor force. Around 10% of the price of each tree is put into a Forest Guard Endowment Fund for long-term guarding and protection of our sites. - work carefully with all levels of government to secure written agreements designating the restoration sites as 'protected in perpetuity'.
- focus on helping locals fall in love with their forest, to recognise and benefit from the restored forest through an increase in fisheries, improved farming, cleaner water, and the formation of microenterprises. - do not plant in logging areas. There is never a 100% guarantee that some form of illegal harvest will not occur. However, everything is done within legal limits to ensure the restoration sites are guaranteed to stand in perpetuity.
- plant agroforestry species (fruit, fodder, and construction species designed to provide food security and benefit legitimate human needs). Over time these trees become a source of sustainable income. - do everything possible to supply the locals with alternative fuel sources (fuel-efficient dry wood stoves and solar parabolic stoves), which reduces and/or eliminates their dependence on charcoal.

How can I improve my climate impact further?

We're glad to see you're interested in reducing your carbon footprint even further! How big your carbon footprint is depends on your lifestyle. Therefore, small but significant behaviour changes can make a big difference. Simple things such as switching to a green energy provider, eating less meat and dairy, and using less water all reduce your carbon footprint. Making a conscious effort to reuse and repurpose items will also help lessen your environmental impact. For example, using less plastic (or even better going plastic-free!) and buying second-hand. Slightly more costly ways to reduce your carbon footprint include making your home more energy efficient and making the switch to an electric car. Although more expensive, these changes can drastically reduce your carbon footprint.

What carbon capture figure are you using per tree?

The mangrove trees planted by our partner Eden Reforestation Projects have a lifetime growth of 25 years and on average absorb 308kg of carbon. It is well documented that waiting 25 years for measures to have their effect is not the solution. For that reason, we use a C02 value of 86kg per tree planted, to align with scientist rally calls that we urgently need to be taking action which has an effect prior to 2030.
