If we’re talking about general technologies that are becoming more widely spread in educational apps, they are:
Augmented Reality (AR). Good examples of apps using AR are Star Walk and Human Anatomy Atlas.
Artificial Intelligence (AI). Apps like Thinkster and Brainly use AI to improve user experience.
Gamification. It’s not exactly a technology but a technique encouraging users to study with game-like experiences: XP, game lives, scores, and so on. Duolingo and Yousician use this technique in their apps.
The final tech stack depends on the feature list and project requirements. Contact us to get consulted about the tech stack for your project."
