Based on the users' reviews of the Electrostatics app, here are three cons and pros in English, limited to 15 words each: **Cons:** 1. "Crashy and unpredictable, often freezes or stops responding during complex calculations." 2. "Limited simulation options and lack of customization for specific experiments." 3. "No clear instructions or guided tutorials for new users, leads to confusion." **Pros:** 1. "Intuitive interface and easy-to-use simulations make complex concepts more accessible." 2. "Accurate and realistic simulations of electrostatic phenomena, great for educational purposes." 3. "Comprehensive library of pre-built simulations and examples for various electrostatic scenarios."
