Sequence 1
Usual care for 2 weeks followed by using patientMpower application \[+digital weighing scales \& BP monitor\] for 4 weeks followed by sham application (without digital scales or BP monitor) for 4 weeks. patientMpower application: electronic health journal for patient to record weight, blood pressure, medication adherence and symptoms sham application: dummy application which does not allow recording of weight, blood pressure, medication adherence and symptoms
Sequence 2

SECONDARY outcome

Timeframe: 28 days

Population: All patients who started the patientMpower observation period and provided a response to the questionnaire

Questionnaire-based assessment: 7 questions. \[pMp = patientMpower intervention\] 1. using pMp helped me to take correct dose of my medicines every day 2. using pMp gave me more confidence/greater sense of control in managing my health 3. my preference for using pMp 4. my difficulty rating in using pMp 5. effect of using pMp on my well-being and daily life 6. do I want to continue using pMp after study end 7. did I like using pMp Possible responses Q1, Q2: strongly agree/agree/disagree/strongly disagree; Q3: yes/no preference/no; Q4: very easy/easy/difficult/very difficult; Q5: positive/negative; Q6: yes/no; Q7: 10-point linear scale: 1 (did not like at all) to 10 (liked a lot)
