Based on the user reviews on the Apple App Store, here are three pros and cons of the "First Piano - Nursery Rhymes Play Along Keyboard" app: **Pros:** 1. Engaging and educational: "Loved watching my 2-year-old learn and play piano, a great way to introduce music!" 2. Easy to use: "Simple and intuitive design, my kid had no trouble playing along with favorite nursery rhymes." 3. Fun and entertaining: "My child giggles and has a blast playing piano with this app, a great way to encourage creativity!" **Cons:** 1. Limited song selection: "Wish there were more songs to choose from, especially more modern and popular nursery rhymes." 2. No multi-touch support: "Frustrating that it doesn't support multi-touch, makes it hard to play complex melodies." 3. No ability to create own songs: "Would be great if we could create our own songs or compositions, current feature set is limited." Let me know if you'd like me to elaborate on these points or if there's anything else I can help you with!
