PMP AWS NCLEX CFA Prep — Certo
Offline certification practice
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Build a decision journal for each certification. Record your reasoning and lessons alongside offline domain practice and spaced review.
Certo combines professional certification practice with a personal Decision Journal for PMP, AWS Solutions Architect Associate, NCLEX-RN and CFA Level I.
DECISION JOURNAL
Record a scenario, your decision, supporting evidence, rejected alternatives and the lesson learned after reviewing an explanation. Each certification has its own journal, stored on your device.
PRACTICE AND REVIEW
Browse certification domains, practise questions, take timed mock tests and revisit mistakes using spaced repetition. View your recorded accuracy and domain progress. Practice results are learning indicators, not official scores or a guarantee of passing.
OFFLINE STUDY
The question bank is bundled with the app. No account is required. Study progress and journal entries stay on your device. You can export and restore a local backup.
PURCHASES AND ADS
Each certification is a separate one-time purchase unlocking that certification's question bank and unlimited mock tests and removing ads while it is active. Purchases do not unlock the other certifications. The free version includes ads and usage limits. Restore Purchases is available on purchase screens. There are no subscriptions.
