Best App for Duolingo English Test 

Your choice of the best Duolingo English Test app depends on your need for vast question sets, expert video guidance, or authentic AI scoring. Heading into late 2026, these are the top-ranked apps:

• LUME: Best for All-in-One Multi-Test Prep

Lume is a fresh newcomer for English learners. It is especially suitable for mobile-first learners. Whether you are taking the DET, IELTS, or PTE, this app provides the most advanced technological experience.

Key Feature: The custom Study Planner is a standout. It creates a daily path based on your goals; consequently, you can maintain discipline without burnout.

Pros: Lume offers a premium UI/UX and an enjoyable interface. It also provides intelligent analytics to track your weekly progress.

Cons: Since it covers various exams, the DET-specific strategies lack high-level depth. The AI feedback is solid, but it does not reach the “hand-holding” precision of Arno.

• Arno: Best for AI Feedback & Writing/Speaking

This is the go-to app if you find it hard to improve your Speaking and Writing (Production). It doesn’t just offer exercises; it acts as a tutor that highlights the “gap” you need to close.

Key Feature: Arno’s secret sauce is its ability to optimize your answers. The AI system grades your work and provides native-style rewrites to push your score toward the 130+ range. 

Pros: It features a highly reliable score predictor and an endless question bank. Additionally, every new account will get a free full mock exam.

Cons: Premium features, such as in-depth corrections, require credits, which can be expensive for heavily practicing users.

• DET Practice: Best for Volume & Simulation

If you want to build test-taking endurance and feel the real exam pressure, don’t miss DET Practice. This platform’s Adaptive Test technology is incredibly close to the real thing.

Key Feature: With over 18,000 questions, the database is enormous. The mock tests are powered by smart algorithms that adjust difficulty based on your performance to recreate the real test logic.

Pros: As a Gold Partner, they provide updated content and 24-hour full-feature trials. Scoring is completed in less than a minute.

Cons: The interface is somewhat complex, and the site includes frequent upselling ads.

• DET Ready: Best for Video Instruction

DET Ready is the #1 option for those who seek both practice and “hacks” to optimize their scores. It is not only a practice tool, but it also functions as a structured educational ecosystem.

Key Feature: High-quality video tutorials are the biggest draw. Teacher Luke explains time allocation and core logic for every format. This helps students avoid rote learning.

Pros: Reliable content from a top expert and a beginner-friendly roadmap. The VIP package offers deep support.

Cons: A limited question bank of 5,000+ items. Most advanced tools are locked, so free resources are quite limited.
