User reviews

$30 monthly

$30 monthly for incorrect answers are you serious? And your app works incorrectly it doesn’t count my progress.
It was $9 couple months ago.
I don’t recommend this, they have only 50 free questions, and wrongs answers that doesn’t match with the real test, don’t waste your time.
Also it has doubtfully high ratings

Response from developer

Thank you for the feedback. A few facts, for you and for anyone else reading: Progress: a major update (3.2.1) shipped the day before your review, and we are actively investigating whether it introduced a progress-tracking bug. If you email contact@cdlhelp.com with your iOS version, we can pin it down faster - and we'll make it right if there's an issue. That being said, this is the first report we're getting in regards to progress tracking issues. Price: the monthly plan has never been $9 - the lowest monthly price in our history was $12.99, back in 2022, and monthly has been $29.99 since 2024. You may be remembering a $9.99 weekly option we briefly offered; per month, that actually cost more than the monthly plan. There are also 3-month, 6-month, and annual plans - the annual works out to about $12.50 per month. Results and ratings: since we added an in-app prompt in March asking drivers how their exam went, more than 300 have told us they passed - over 160 in July and August alone. Our 4.9 average comes from more than 5,200 ratings collected through Apple's own rating system since 2022. Questions: the bank holds 2,937 questions, drawn from the official state CDL handbooks and maintained in ten languages. Every question has a "Report an error" button; a person reads each report, and genuine mistakes get corrected. If you remember which test and question felt wrong, that report is the fastest route to a fix. If the app let you down, we'd like the chance to make it right: contact@cdlhelp.com.
