Know the mistakes before you make them. 100 Dev Mistakes is a growth checklist that covers the 100 mistakes junior developers make most, so you can grow faster and stop repeating the same errors. The mistakes are organized into 10 categories: coding habits, debugging and problem solving, version control and collaboration, design and architecture, testing and quality, learning and growth, communication, infrastructure and deployment, security and privacy, and performance and optimization. Each one is explained in three parts: what happens, what to do, and what you learn from it. Check off the mistakes you have experienced, then answer the reflection questions for each one. With 400 questions in total, the reflection journal turns a quick read into real understanding. You can follow your progress by category and overall across all 100 mistakes, and bookmark anything you want to revisit. Your data syncs through iCloud (CloudKit) across iPhone, iPad, and Mac, so you can pick up wherever you left off. The app collects no personal information, and there are no analytics and no ads. Try the first 30 mistakes (3 categories) for free. Upgrade to PRO to unlock all 100. PRO is available as a monthly or yearly subscription, with the yearly plan saving up to 50% compared to monthly, or as a one-time lifetime purchase. Monthly and yearly subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription anytime in your Apple ID settings. Don't wait to learn it the hard way. Know the mistakes early, learn from them, and grow faster as a developer.
