Currently, I have to remember to check my plan each day. It would be helpful if I could set a notification for a specific time (like 6 AM) to remind me of my planned workout. This would help me stay consistent with my routine. I&apos;m using the iOS app version 8.2.&quot;</p><p>This feedback is specific, explains the benefit, and includes relevant details.</p><h4 id="content-feedback-example">Content Feedback Example</h4><p>Subject: Feedback: More beginner-friendly strength workouts</p><p>&quot;As a beginner (just started 3 weeks ago), I&apos;m finding the intermediate strength workouts challenging to follow. The movements are clear, but the pace is fast for someone learning proper form. Could you add more beginner variations or slow-paced strength sessions? I love the yoga and HIIT beginner options - similar approach for strength would be amazing.&quot;</p><p>This explains the user&apos;s situation, identifies the issue, and suggests a solution.</p><h4 id="user-experience-feedback-1">User Experience Feedback</h4><p>Subject: Feedback: Recipe search functionality</p><p>&quot;The new recipe search feature is excellent! Being able to filter by dietary preference and cooking time has made meal planning so much easier.
