CertStreak: AZ-900 & AI-900
Azure Fundamentals Practice
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
AI-900 is live: 100 new questions alongside the 199-question AZ-900 bank. Ten a day, a readiness score with arithmetic behind it, and a path that says what to study next.
Most exam-prep apps hand you a pile of questions and a percentage that means nothing. CertStreak gives you a route through the material, and a readiness score you can actually trust.
WHAT YOU GET
• A path, not a pile. The question bank is cut into numbered practice exams, each one a miniature of the real paper — the same domain mix, roughly the same length, roughly the same clock. Finish the series and you have covered the bank.
• A readiness score with arithmetic behind it. Domain weight × accuracy × coverage, per domain, summed. It cannot be flattered by getting four easy questions right, and it reads "—" rather than 0% before you have answered anything.
• Tutor or Timed. Tutor explains after every question. Timed runs the exam's own clock, holds the explanations back, then hands them over in a review pass — wrong answers first, your answer set against the correct one.
• Four question formats. Single choice, multiple select, ordering and matching — the shapes the real paper uses, not just A/B/C/D.
• Pace coaching. Your answering time is measured against the exam's real per-question budget, and you are told when you would have run out of time.
• Streaks counted from your own midnight, not a server's. An unfinished today does not break anything.
• Per-question notes. Write it down mid-session; the notebook keeps them together.
• Exam-date countdown. Set the date and get a reminder three days and one day before. That is the whole of the nagging.
• Certification tracking. Log a real sitting with its score. Re-certifying adds an entry, and a failed retake cannot un-earn a certificate you already hold.
EXAMS AVAILABLE TODAY
• AZ-900 Azure Fundamentals — 199 questions across all three domains
• AI-901 Azure AI Fundamentals — 100 questions
More of the fundamentals track is in progress. Every exam carries its own official domain weights, passing score and duration, so nothing is one-size-fits-all.
YOURS, AND OFFLINE
Your progress lives on your device. An account is optional and exists for exactly one reason: backing that progress up so a new phone does not start from zero. You can delete the account, and everything in it, from inside the app.

Free gives you the first practice exam on the roadmap and ten questions a day — enough to build the habit and find out whether the app suits you.
