Comments on Devmaxx for Android

★★★★★ Brian Kinyua · Jul 11, 2026
Just started using it, I love your TikTok videos, really helpful. Kind of videos that make me not want to leave TikTok
★★★★★ Sahib Sharma · Aug 9, 2026
Really well-designed for someone who's truly looking to improve. Loved it - would actually want to get in touch about more happy goals together
★★★★☆ Mayank Mehta · Jul 11, 2026
Please keep a free tier for this application for students. It would really help them learn a lot
★★★★☆ Bjørn O. · Oct 7, 2026
Looks nice, missing drag and drop in list sorting, missing a free version
★★☆☆☆ Basile Maret · Oct 12, 2026
Only usable with a subscription. It starts with a free assessment, then forces you to create an account and once all this is done blocks you from using the app unless you start a subscription. The idea looks nice though
★☆☆☆☆ Nikhil P · Aug 7, 2026
Installed the app, created the account and logged back in next time only to be hit with the subscribe to devmaxx screen with no option to opt out or just explore the app more. Have been stuck on the subscribe page for a while. Had to uninstall the app. I don't recommend the app, it's better to find your resources online.
★☆☆☆☆ Ivan Pavlina · Oct 13, 2026
Tell claude to let users know app is useless without paid subscription before you waste 10 minutes for stupid quiz. I want 10 minutes of my life back
★☆☆☆☆ Mark Reonal · Oct 7, 2026
Subscriptions or go home. Give at minimum a small free tier to experience the app.
★☆☆☆☆ Oliver Anteros · Oct 27, 2026
The premise is good, but it feels wrong to be asked to pay a monthly subscription after having created an account and given away personal information...

Description by Arjay McCandless Written by the developer, not by AppBrain. Click to read.
System design is becoming one of the most important skills for software engineers. Many companies now require a dedicated system design interview, and your career growth often depends on your ability to design large-scale systems. Devmaxx gives you everything you need to level up and master system design. New system design questions every day, a massive backlog of questions you can scroll through and solve instead of doom scrolling on your phone, bite size lessons on system design fundamentals with quizzes at the end to make sure you understand the concepts, and ofc progression and leveling as you get better and better.

If you don't know the answer or you get the question wrong,

What you’ll get:
• A new system design question daily
• A massive backlog of 300+ system design questions
• Clear explanations for every answer
• Progress tracking across each subject
• Bite size lessons for every core system design fundamental
• Linked resources to go deeper
• Access to a private community of developers learning and building the same things as you


If you’re preparing for interviews, this builds daily momentum.
If you’re already working as an engineer, this keeps your fundamentals sharp.

Open the app. Answer one question. Land the offer.

All features described above require a subscription.
