CareerTree

Offline SQL learning

Free · In‑App Purchases

Build skills for your next career step. Explore data-analysis work through short lessons, career trials and practical tasks. Start with the Data Analyst path. Learn SQL by trying one small thing at a time. CareerTree starts with a Data Analyst path: 10 short lessons in SQL foundations, data quality and reporting. Read an explanation, check your understanding, then put it to work. - 30 quiz questions with explanations, plus smart review for questions you missed. - Nine query-writing tasks on sample data and one short analysis note. - Four Challenge Lab missions with two sample-data versions to help you check a result and explain its limits. - Three optional career trials about data-analysis decisions. - Career Proof records and a visual Career Tree to keep track of work you have done. The starter path does not require an account or a subscription. Bundled lessons and previously opened work can be used offline. Other career paths are not available yet. Career Proof records are practice records, not a professional qualification or a job guarantee. In ad-supported versions, the first new learning session each local day is ad-free. Later eligible sessions require a completed rewarded ad break or an active ad-free subscription. One break may contain more than one video; CareerTree does not request two separate ads for one unlock. There are up to five completed ad-supported unlocks per day. Resuming work, reading saved work, Settings and Help do not need an ad. New ad-supported unlocks need a connection and an available ad. Where offered by your app version and store, the optional ad-free subscription renews monthly. The US base price is USD1.99/month, with no free trial. Your store shows the actual local price and renewal terms. Manage or cancel your subscription in your Apple Account settings. Deleting the app does not cancel a subscription. Developer tips are separate one-time purchases, with US base options of USD0.99, USD2.99 and USD4.99. Tips do not remove ads, unlock content or provide another benefit. They are not subscriptions or charitable donations. In versions with guest purchases, you can subscribe or leave a tip without a CareerTree account. Restore an ad-free subscription with the same Apple Account you used to subscribe; this does not restore learning records. Earlier versions may require sign-in before buying. Website Pro is separate. Deleting a CareerTree account does not cancel store billing. Signing in is optional. Without an account, your progress and saved work stay only on this phone, and deleting the app, resetting the phone or switching phones can erase them. After you sign in, you can review what is on this phone and connect it only when you confirm; signing in alone does not move anything. Backup to CareerTree is a separate choice, exploration backup has its own choice, and drafts are not backed up. On another device, only records already backed up to that CareerTree account can be restored. Availability of sign-in, backup and purchases depends on your platform and version. Questions?

Keep learning SQL with 10 lessons, smart review, Challenge Lab and saved Career Proof records. Optional monthly ad-free access and one-time developer tips are offered where supported. This update improves backup completion and progress ordering, store-price refresh, purchase confirmation and navigation while keeping your local learning progress. The starter path still needs no account or subscription.
