Cadence
A learning app with a personal tutor, for any topic you choose
This is our app. See the disclosure above.
Cadence brings the best ideas from books, research, expert practice and standout articles into a course shaped to your goal. You choose the topic, from a work skill to a subject you are curious about, and say where you are starting. Cadence plans an ordered 7 to 30 lesson course around it and tutors you through it. Each lesson can be read or played as audio, Spark, the tutor, gives a hint when an answer misses and brings earlier ideas back for review, and practice gives feedback on your own answers.
Best for
Turning your own starting point into one coherent course you can keep progressing through.
Not for
Anyone who needs a recognized certificate, a named instructor, or a language course with speaking practice.
Price
Free to start, with 2 new lessons a day, audio and 4 lesson voices included, and 4 new custom courses a month. Plus makes new lessons, new courses, and Ask Coach unlimited and includes 10 practice sessions a day, adds 8 more voices for 12 in total, and raises live voice practice to 15 minutes a day, for US$49.99 a year on the web, with a 7-day trial.
Mimo teaches Python, JavaScript, HTML, CSS, SQL, React, Swift, and related development skills through guided paths, short coding exercises, and projects. You write code during the lesson, then combine the ideas in work you build yourself.
Best for
Starting coding through small interactive exercises before moving into larger projects.
Not for
Learning software development without eventually building and debugging projects outside the guided lesson.
Price
Free to start. Paid plans add broader access to paths, projects, certificates, and career-focused features.
Courses and programs from universities and companies
Coursera offers provider-defined courses and programs with course-dependent assignments and credentials. Its free preview model generally opens the first module, rather than promising free completion of the whole course.
Best for
A defined syllabus or a specific provider's certificate, after checking its requirements.
Not for
Assuming every course is included in a subscription or every credential meets a particular employer's requirement.
Price
First-module previews are available for nearly every course. Full courses, programs and Plus have separate paid terms; check inclusion and your local offer.
Practical and technical skills, bought one course at a time
Udemy offers courses from individual instructors. Compare the syllabus, preview, recording date, exercises and prerequisites for the specific course. Features and access can differ between individual purchases and subscriptions.
Best for
One concrete tool or technique you need soon.
Not for
Assuming one course's format, quality or access terms apply to the whole marketplace.
Price
Individual courses and subscription options are available. Check what the particular purchase includes and its final price.
Brilliant offers guided STEM courses with interactive problems and explanations. Try material at your level and inspect the feedback; the format alone does not prove it teaches more effectively than another app.
Best for
Working through interactive problems in a supported subject.
Not for
An unsupported subject or unlimited free daily study.
Price
Free users receive two keys daily, each opening a lesson or practice set, with sequential access and ads. Premium removes those limits and adds full Koji access.
edX offers courses and programs from education providers. Many courses have a free audit track with time-limited readings, video, discussion and ungraded assignments. Graded work and certificates generally require a paid track.
Best for
Inspecting or studying a specific academic course with known prerequisites.
Not for
Assuming audit access lasts indefinitely or includes a certificate.
Price
Audit access is available on many courses, generally for four to twelve weeks. Check the course's paid track and exclusions.
Khan Academy provides free videos, articles, lessons and practice across school subjects and other areas. Course content and exercises vary by subject. Its core library is separate from the eligibility and payment rules for Khanmigo learner tutoring.
Best for
Finding explanations and practice for a topic in its free library.
Not for
Assuming a completion record is a degree or that core free access includes every separate tutoring service.
Price
The core learning library is free without ads. Khanmigo learner access is separate.
Original fictional task: draft a 30-minute agenda with 5 minutes for context, 15 for options and 10 for a decision. State that no customer data or names may be used.
Check the result: do the parts total 30 minutes, preserve all three purposes and avoid invented participants or facts? Then change the task to 25 minutes and require a revised allocation. This gives you something concrete to verify.
One successful agenda does not validate a model for other tasks. A useful course should teach how to identify the checks for each workflow, not simply praise a polished response.
Before you choose
Keep verification and authority in the workflow.
Use only employer-approved tools and information you are permitted to share. Check every consequential claim, calculation and action against an appropriate source or review process. A single correct fact cannot establish that the rest is reliable.
Tool-specific skills and general judgment can both matter. For fast-changing interfaces, compare course steps with current official documentation. The course is useful when you can explain what remains under human review.
Put it into practice
Start it today, one lesson at a time.
Cadence builds a course around your goal, with lessons, practice and saved progress. Learn at your own pace. Cadence is our app.
Learn enough of both to complete a permitted task and check the result. The needed depth depends on the workflow.
How can I test a beginner course?
Try a small public or fictional task with known constraints and an answer you can check. Inspect how the course handles errors and uncertainty.
Can I use private work material in practice?
Only within your employer's approved tools and data rules. Fictional or public examples are safer for evaluating an unfamiliar course or app.
