Many of my clients have mentioned they have had help with the following apps.
• Headspace: Guided Meditation and Mindfulness (Free)
• ReSound Relief (Free)
• SleepBug by Arnt-Henning Moberg (Free/£1.99)
• Sleep Pillow by Fitness22 Ltd (Free/£2.99)
• Smiling Minds by Smiling Minds (Free)
• White Noise (Free) by TMSOFT.
For those apps that have a cost, I would suggest just downloading the free versions first to see what different sounds they have before purchasing. If you have any others that you have found useful, please let me know and I’ll add it to the list.
