The HBDI® (Herrmann Brain Dominance Instrument®) is a cognitive styles assessment that defines and describes someone’s thinking preferences across the Whole Brain® Model. Originally developed at General Electric, the HBDI® was created to help people understand their thinking in order to solve problems in a business environment. It has since been completed by more than two million people around the globe and has become the assessment instrument of choice at many of the world’s most successful organizations, including 97% of Fortune 100 companies, leading universities, governments and non-profit institutions. Please note that the HBDI® is a professional tool and the HBDI® App should be used in accordance with best practices. All profiles should be debriefed by a Herrmann International Certified Practitioner or an approved alternative to avoid misinterpretation and misuse. The HBDI® App is not intended to replace a debrief with a Certified Practitioner, but rather as an alternative way of accessing the HBDI® profile information during the debrief, and to help reinforce and apply the insights to everyday situations after the debrief.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Qstream holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: HBDI® has 98 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Qstream's written reviews are positive against 81% of HBDI®'s, so the app with the better star average is not the one people write more warmly about.
Qstream ships an update every 3 months, HBDI® every 6 weeks. The most recent releases landed on June 7, 2026 and September 12, 2026 respectively.
