Niix fit is fabulous

With so many fitness apps available it is hard to know where to start, I was recommended this by a friend and I have been thrilled with it. The programmes are excellent and there are lots of levels to choose from. The app itself is well set out with a great library section so you can really check out each exercise to make sure your technique is spot on. I was returning to exercise after many years and find the classes really achievable and easy to follow at home, within a week I was feeling stronger and more flexible. After joining the 4 week June challenge I feel better than I have in years, it was a very supportive community and Nicky herself is always on hand to help support and guide you.
Can not recommend this app highly enough.

Update - app now working and amazing customer support

Update - Since logging my problem with the app, Nicki / her team have been in touch and have worked with me to resolve the issue (I had managed to set up two accounts). I had a number of exchanges on a Sunday and I couldn’t have been happier with the service. I’m now logged in and ready to go.

I have subscribed to the free trial, logged in but the app still won’t move past the subscription options page. I’ve deleted and re-downloaded the app, and turned my phone off and on!! Please can someone respond to this or I will unfortunately need to cancel my subscription.

Hi Mitchy12344 I am sorry to hear you are having problems accessing the app. Please contact and we will be happy to assist and get you set up. Thanks.

Bobby is amazing😄 ,

Great to fit into my day and effective!

I am 47 and have always busy running around after my children. No two days are the same so getting into a fixed exercise routine is not always easy but I can fit Niix in to when I have time. The App is easy to use you run through a programme so is not the same exercises day in day out and I can do as little or as much as I like depending on what I am doing that day. Nicky is motivational and easy to understand. It is aimed at over 40’s but to be honest this could be used by people of all ages and levels of fitness. The programme works as I’m not only enjoying it but seeing the benefits too.

Developer Response ,

So pleased you are enjoying our app. We specifically designed niix around you, helping you fit exercise into your life any time, any place. Great to hear that you are reaping the benefits. Keep up the good work :-)
