Panic Ease

Panic Ease was created by someone who has been there and done that, through panic attacks, relentless anxiety and the frightening physical sensations that can come with them. Its tools are shaped by what has genuinely helped in real life, while its educational content is grounded in established evidence and reputable clinical guidance. When panic hits, even simple instructions can feel like too much. Panic Ease gives you something immediate to see, touch and follow. Tap Help Me Now and choose what feels manageable: distract your attention, reconnect with your surroundings, follow one simple action, work with your breathing or ride the sensations without fighting them. Panic Ease includes tactile, sensory tools designed to keep your hands, eyes and attention occupied: • Hold and move with a flowing light • Feel a steady pulse through your finger • Press soft pads in numbered or free patterns • Follow and catch moving lights • Trace glowing shapes • Count objects and solve gentle attention exercises • Use sound, colour and room-based grounding prompts • Squeeze and release with visual and haptic feedback • Follow the rise and fall of the Ride It wave • Try small puzzles when you want something absorbing to focus on There are no streaks, lives, countdown pressure or judgements. Stop whenever you want and choose something else. BREATHING THAT MEETS YOU WHERE YOU ARE Choose a straightforward guided breathing rhythm, or teach PanicEase the pace of your breathing by tapping along. The app can begin with your current rhythm and gradually make it more even. If the pace no longer feels right, you can adjust it again at any time. You choose the length or leave the session open and continue for as long as you want. BUILD YOUR PANIC KIT Save the tools that feel most useful and keep them close. Choose one to open first when you tap Help Me Now. Optional before-and-after check-ins let you notice patterns over time without turning your feelings into a diagnosis or a score you must improve. UNDERSTAND WHAT IS HAPPENING When you have more space to read, explore clear evidence-informed information about panic and anxiety, including: • Common physical symptoms and why they can feel frightening • The panic feedback loop • Anticipatory anxiety and avoidance • CBT and panic-focused CBT • Exposure and interoceptive exposure • Acceptance-based approaches • Medication, sleep, caffeine, alcohol, stress and exercise • Established treatments and where to seek professional support Medical evidence and lived experience are clearly labelled and kept separate. Sources and review dates are included so you can see where the information comes from. OPTIONAL APPLE WATCH SUPPORT The Apple Watch companion can add gentle wrist haptics during supported activities and show a simple heart-rate direction such as rising, broadly steady or easing down. Heart-rate information is provided as context only. It cannot determine why your heart rate changed or whether you need medical care. PRIVATE BY DESIGN • No accounts • No advertising • No tracking SDKs • No third-party analytics • Panic sessions and check-ins remain on your device • The app works offline • Delete your locally stored data whenever you want PanicEase also supports VoiceOver, Voice Control, Dynamic Type, Reduced Motion, Reduced Transparency, increased contrast and an optional reduced-stimuli mode. PanicEase is a support and educational tool. It does not diagnose, treat or cure anxiety, panic attacks or any medical or mental-health condition. It is meant as a companion only. It does not replace professional healthcare, but it can be used in conjunction with other therapies. New, severe or unusual physical symptoms should not automatically be assumed to be anxiety. Seek appropriate medical help when needed.
