The app was developed based on the principles of microlearning. The study aimed to explore carer perspectives on the acceptability of the app and determine whether the app increased knowledge and confidence in their caring role. Methods: In this concurrent mixed methods study, participants completed quantitative questionnaires at baseline and at the end of weeks 2 and 6, which examined caregiving self-efficacy, preparedness for caregiving, caregiver strain, pressure ulcer knowledge, and app acceptability and usability. A subsample of participants participated in a ``think aloud'' interview in week 1 and semistructured interviews at the end of weeks 2 and 6. Results: Of the 32 participants, 23 (72{\%}) participants completed the week 2 and 16 (50{\%}) completed the week 6 questionnaires; 66{\%} (21/32) of carers participated in qualitative ``think aloud'' interviews, and 18 (56{\%}) also participated in semistructured interviews at week 2, and 13 (41{\%}) at week 6. Pressure ulcer knowledge scores significantly changed (F1,6.112=21.624; P=.001) from baseline (mean 37.5; SE 2.926) to the second follow-up (mean 59.72, SE 3.985). Regarding the qualitative data, the theme ``I'm more careful now and would react to signs of redness'' captured participants' reflections on the new knowledge they had acquired, the changes they had made to their caring routines, their increased vigilance for signs of skin damage, and their intentions toward the app going forward. There were no significant results pertaining to improved preparedness for caregiving or caregiving self-efficacy or related to the Caregiver Strain Index. Participants reported above average usability scores on a scale of 0 to 100 (mean 69.94, SD 18.108). The app functionality and information quality were also rated relatively high on a scale of 0 to 5 (mean 3.84, SD 0.704 and mean 4.13, SD 0.452, respectively). Overall, 2 themes pertaining to acceptability and usability were identified: ``When you're not used to these things, they take time to get the hang of'' and ``It's not a fun app but it is informative.'' All participants (n=32, 100{\%}) liked the microlearning approach. Conclusions: The iCare app offers a promising way to improve informal carers' pressure ulcer knowledge. However, to better support carers, the findings may reflect the need for future iterations of the app to use more interactive elements and the introduction of gamification and customization based on user preferences.
