About

DevEducation

Features
Read full description

DevEducation starts with coloured blocks and ends with real code. It teaches by doing, not by reading. Nine courses take a complete beginner from the first coloured block to the first line of real code: Scratch, mBlock, HTML, CSS, Python, Java, C#, Arduino and robotics. Every lesson is made of small steps β€” drag a block, fix a line, predict what the code will print β€” so progress does not depend on reading long paragraphs. Sixteen mini games practise the same ideas a different way: sequencing commands, spotting patterns, matching terms, steering a character through a maze. Quizzes after the lessons check what stuck, with an explanation after every question. A wrong answer never costs points. Pick one of five characters (Puf, Mia, Bit, Kaşif, Bug), earn coins while learning, and spend them on hats, glasses and shoes. Behind a parent gate: progress, the weekly goal and certificates. No purchase and no external link is reachable without passing that gate. The interface is available in Turkish, English, German and Spanish. DevEducation Pro unlocks nine further games and all courses. Prices are shown in the app, in your own currency, before you buy anything. Devkom Pro is an auto-renewable subscription. It renews automatically unless it is cancelled at least 24 hours before the end of the current period, and payment is charged to your App Store account. You can manage or cancel your subscription in your App Store account settings.

Verdict

The call

DevEducation also leads on update cadence (every 6 days vs every 2 months) and iOS requirement (13.0 vs 15.1). GetPrincipia's advantage is ads (none vs shown). On price and device support there is nothing between them.
