This study is a two-arm, randomised controlled cross-over feasibility study with a nested, optional qualitative study. The intervention consists of a self-guided smartphone app (Orbi) based on cognitive behavioural therapy (CBT) principles, which is designed to support psychological adjustment in long-term physical conditions. Orbi is an app adaption of an existing, evidence-based web-based intervention COMPASS. The control condition consists of usual charity support (UCS) for the relevant long-term physical health conditions (LTCs). All charity support includes a helpline which can be accessed via telephone or email. The goal of this trial is to evaluate the feasibility of Orbi and the main questions it aims to answer are: 1. Is Orbi a feasible and acceptable intervention for individuals experiencing psychological distress related to LTCs? 2. Which aspects of the Orbi app and the trial enhance or diminish participants' experiences? Participants will: * Be randomised and each participant has an equal (50 %) chance of being assigned either to the Orbi+UCS group or to UCS group alone for 12 weeks. After 12 weeks, they will be crossed over to the alternate condition for another 12 weeks * Complete questionnaires to assess psychological distress and intervention engagement at baseline, 6 weeks, and 12 weeks. * A subset of participants will be invited to take part in a nested, optional semi-structured interviews to explore their experiences using Orbi and participating in the study.

Orbi is adapted from COMPASS, a web-based cognitive behavioural therapy (CBT) intervention based on the Transdiagnostic Model of Adjustment in Long-Term (physical) Conditions Model. Orbi is made up of 13 topics, each exploring a different challenge faced by individuals with a LTC(s). Orbi is a self-guided CBT programme with no therapist involvement.

Compare post intervention scores on Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS-15) adjusting for baseline differences between groups
A 15-item scale assessing symptoms of anxiety and depression. It includes items from the Patient Health Questionnaire Scale (PHQ-8) for depression and the Generalised Anxiety Disorder Scale (GAD-7) for anxiety, each scored on a 4-point Likert scale from 'not at all' (0) to 'nearly every day' (3). Total scores range from 0 to 45 with higher scores indicating greater symptom severity.
Time frame: At baseline, 6 weeks (mid-study) and 12 weeks (end of study)
Compare post intervention scores on Patient Health Questionnaire Scale - (PHQ-8) adjusting for baseline differences between groups
8-item questionnaire scoring the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria for depression on 4-point Likert scales from 'not at all' (0) to 'nearly every day' (3). Total scores below 5, 10, 15, 20, and up to 24 are categorised as none-to-minimal, mild, moderate, moderately severe, and severe depression.
Time frame: At baseline, 6 weeks (mid-study) and 12 weeks (end of study)
Compare post intervention scores on Generalised Anxiety Disorder Scale (GAD-7) adjusting for baseline differences between groups
A 7-item questionnaire assessing the severity of generalised anxiety symptoms based on DSM-IV criteria. Each item is scored on a 4-point Likert scale from 'not at all' (0) to 'nearly every day' (3). Total scores range from 0 to 21, with cut-off points at 5, 10, and 15, indicating mild, moderate, and severe anxiety, respectively.
Time frame: At baseline, 6 weeks (mid-study) and 12 weeks (end of study)
Compare post intervention scores on Illness Related Distress (IRD) scale adjusting for baseline differences between groups
A 14-item scale assessing how a long-term physical health condition has affected the psychological distress experienced by an individual over the last two weeks. Intrapersonal IRD = items 1-7 (cut-off = 15); Interpersonal IRD = items 8-14 (cut-off = 12). The scale is augmented by 3 additional items. Two horizontal visual analogue scales ranging from 0 to 10: One indicating the amount of psychological distress that is attributed to having one or more physical Long Term Condition (LTC) over the last two weeks; one indicating the severity of psychological distress related to the LTC over the last two weeks. The final item asks the respondent to specify which LTC they are attributing their psychological distress to (as many people are affected by multiple LTCs in parallel).

Compare post intervention scores on Work and Social Adjustment Scale (WSAS) adjusting for baseline differences between groups
A 5-item scale measuring the impact of mental health issues on daily functioning across work, home management, social leisure, private leisure, and close relationships. Each item is scored from 0 (no impairment) to 8 (severe impairment). Total score ranges from 0 to 40, with higher scores indicating greater functional impairment.

Comparison between intervention and control groups on Health Service Utilisation
Usage of health services will be captured with the Health Service Use Questionnaire. Participants will indicate whether they have accessed key services, including general practitioner (GP), psychological or counselling services, and emergency care during the past 3 months. For each service reported, additional items capture (i) the number of contacts, (ii) the mode of contact (e.g., in-person, telephone, video), and (iii) the duration of the most recent contact.
Time frame: At baseline, 6 weeks (mid-study) and 12 weeks (end of study)
Comparison between intervention and control in access of charity services
Participants will also be asked about their access of charity resources. A multiple-selection drop-down box will show the following options (charity helpline, online forums/networks/phone counselling, information booklets, others)
Time frame: 6 weeks (mid-study) and 12 weeks (end of study)
