The app is excellent. I've seen complaints about the cost, but it's not greed - far from it. Parts are totally free, and at roughly £15 per year, it's affordable for almost everyone in the UK. The business must have operating costs, so I'm happy to pay it. Perhaps there could be an option to sponsor the cost of someone who can't afford it. But yes, making CBT exercises digitally accessible transforms the effectiveness of the techniques for me.

Hi James, thank you so much for your kind words - it's so good to read that you're finding WorryTree effective for your CBT practices. I absolutely love your idea of providing an option to sponsor the cost of our app for someone who can't afford it and so we'll definitely be looking into how we might make that work. Best wishes, Louise (Founder)

Terrible, I downloaded the app, replied to email etc went into the app, was presented with the record worry text box which I spent some time writing down, it said something like swipe left to continue which I did, after that the text worry sections were greyed out and a subscription option appears, I don't have a problem with subs, however why let me waste my time entering a worry before displaying that, I can't even find what I've written now, I'm annoyed, I'll just delete the app and use notes

Hey Steve - I'm really sorry that you experienced this issue - you should have been given a seven day free trial of all the tools so that you could decide whether WorryTree is right for you and it sounds like you didn't get this. If you could email me directly at hello@worry-tree.com I'll share a 3-month free subscription. BW, Louise, Founder.

Such a shame. I have had this app a long time and found it very helpful in managing my worries. Now they've put it behind a paywall, which is ridiculous for something you can essentially do with a pen and paper. Seems immoral to change it to paywall when some people may rely on this app to help manage anxieties. Uninstalling and looking for an alternative.

Thank you for your feedback Sophie. Unfortunately the cost of maintaining an app has meant that we do now need to charge a small fee. However, we have tried to keep this as low as possible. If affordability is an issue for you, please do contact us at hello@worry-tree.com so that we can help. Best wishes, Louise (Founder of WorryTree).

What’s new

In this update: the habits and goals tracker is simpler, and we’ve tidied up a few bugs in the background. Don’t forget - setting your values first unlocks the goals and habit tracker. Thanks for being part of our little family-run journey with Luma. Best wishes, Louise.
