Frequently Asked Questions

A game-based ADHD treatment clinically designed to improve ADHD symptoms, functioning, and attention in adults. For more information, visit www.endeavorOTC.com.

EndeavorOTC is a digital therapeutic indicated to improve attention function, ADHD symptoms, and quality of life in adults 18 years of age and older with primarily inattentive or combined-type ADHD. Because EndeavorOTC is indicated for adults 18 years of age and older, you will be asked to attest to your age upon sign-up. Do not use this app if you have photosensitive epilepsy, color blindness, and physical limitations that stop you from comfortably holding a device. For more indication information, visit our Instructions for Use.

Built with patented, FDA-authorized technology, EndeavorOTC uses a video game experience to strengthen your brain’s ability to focus. It does this by requiring you to do two simultaneous challenges at once: target and navigate. When targeting, you tap specific stimuli while letting other distractions go by. When navigating, you travel through a course to avoid obstacles. Doing both of these at the same time uniquely challenges and alters pathways in the brain, boosting attention and focus. As you progress, the game’s algorithm will measure your performance and adjust in speed and difficulty. In short, as you get better, it gets harder. This results in a personalized treatment experience for each individual, enhancing cognitive functions such as your ability to pay attention, multitask, and prioritize information.

For best results, we recommend playing the game approximately 25 minutes a day, 5 days a week. Our clinical study showed that the best results come with this routine for 6 weeks, although many participants showed substantial improvements in attention and clinical functioning with less play time. For more information about play time, visit our Instructions for Use.

There were no lasting or serious side effects experienced in our clinical trial for EndeavorOTC. Overall, 11 of the participants in the trial (5%) reported a treatment-emergent adverse device event, most commonly nausea (1.8%) and headache (1.4%). There were no serious adverse device events.

EndeavorOTC was studied in over 220 participants over a 6-week period. In our pivotal trial, EndeavorOTC improved ability to focus* and quality** of life in adults ages 18+ with ADHD. Improvements in attention were nearly 7x larger than those seen in the pivotal trial that supported EndeavorRx’s† FDA authorization for kids 8-12 with ADHD.

*As measured by at least a 1.4 point improvement on the Test of Variable of Attention (TOVA®) Attention Composite Score. The TOVA measures attention and other functions that assess the ability to focus.
**As measured by the validated Adult ADHD Quality of Life Scale (AAQoL). Stamatis, C. A., Mercaldi, C., & Kollins, S. H., J Am Acad Child Adolesc Psychiatry, 62, S318 (2023)

^†EndeavorRx^® is FDA-authorized, supported by 5 clinical studies involving over 600 children with ADHD. In our randomized, controlled clinical study¹, EndeavorRx improved objective attention in children with ADHD ages 8-12. Patients played for ~25 minutes per day, 5 days per week, for 4 weeks – and a more recent trial demonstrated that a second month of treatment can lead to increased benefits. To learn more about EndeavorRx, indications for use, and how to get a prescription for your child, visit EndeavorRx.com. ¹ Kollins et al, Lancet Digital Health 2020. Data from a “Yes-No” Exit Survey.

Yes. While EndeavorOTC users don’t have to be on other medications or treatments for their focus, it absolutely can be used alongside tools for attention. In fact, in our clinical study of EndeavorOTC, those participants that were on stimulant medication experienced just as much benefit, if not more by some measures. Always consult your healthcare provider before changing medications or treatments.

This is the first generation of our product for adults that still includes the core technology that improves attention and focus. We plan to make continuous improvements to the user interface and features to provide users with the best experience possible. We expedited the availability of the first generation of our product for adults given the treatment crisis affecting the ADHD community.

At this time, EndeavorOTC has not been authorized by the FDA. However, EndeavorOTC is built with the same technology behind EndeavorRx, the world’s first FDA–authorized prescription video game treatment for pediatric ADHD. Learn more about EndeavorRx, EndeavorOTC’s Mission, and Akili, the maker of both treatments.

The Focus Score measures how quickly and accurately you can complete a task despite distractions during EndeavorOTC treatment. The goal is to give you an easy way to track your focus improvement from your baseline Focus Score.

At the start of treatment, we’ll provide you with a personalized target score. If you reach this score, data from our clinical study in adults with ADHD predict you are more likely to see meaningful improvements in your ADHD-related symptoms and focus.

As measured by improvement on the TOVA® ACS. Changes in the Focus Score are statistically significantly related to changes in TOVA and other outcomes. Treatment results may vary. Internal data on file.

Our clinical trial data indicate that people who hit their Focus Score target are more likely to see meaningful improvements in ADHD-related symptoms.

In our six week study, increased Focus Scores predicted improvements in ADHD symptoms and quality of life. Those who increased their Focus Score were more likely to report improved ability to:

• Complete projects and tasks on time
• Balance multiple tasks at once
• Keep track of important items like their wallet and keys

As measured by improvement on the TOVA-ACS and AAQoL. Changes in the Focus Score are statistically significantly related to changes in TOVA and other outcomes.Stamatis, C.A., Heusser, A.C., Ala’ilima, T., Simon, T.J., & Kollins, S.H., Neuropsychopharmacol. 48 (Suppl 1), 63–210 (2023).

Your Focus Score can range between 0-100 and is calculated exclusively from gameplay mission data. The score blends three primary parts of mission performance together:

• Navigation ability
• Speed in collecting targets
• Accuracy in selecting targets

We statistically analyzed how individual Focus Scores were related to key results from our clinical trial participants to understand how Focus Score was related to improvements in ADHD-related symptoms and quality of life. The typical target Focus Score improvement will be an increase between 12 to 34 points depending on a person’s starting Focus Score or “baseline”. Based on our clinical trial analyses, reaching this target should be achievable in six weeks depending on a user’s commitment to gameplay (the more you play, the better results you can expect!).

The typical target Focus Score improvement will be an increase between 12 to 34 points depending on a person’s baseline. Reaching this target should be achievable in six weeks depending on a user’s commitment to gameplay (the more you play, the better results you can expect!). That said, progress will vary by person and not all progress is linear. Many players will see a few flat Focus Score updates or even declining Focus Score updates throughout the six weeks. This is common and does not mean that meaningful results can’t be reached. In fact, just the opposite, this could suggest the algorithm has increased the challenge as the person is strengthening their mental processes. So no change in the Focus Score likely indicates the person is performing as well as before, but at more difficult tasks.

If you had already started EndeavorOTC prior to the release of the Focus Score feature, you will be given access to your current Focus Score and updates on your score as you continue treatment. We do not have enough data from you to calculate an accurate personalized target; however, you can use the 12 – 34 point increase range to calculate your goal. You can also compare your progress to those from the clinical trial who engaged in the six-week treatment with the provided percentiles. If you have questions about how you apply this, please reach out to [email protected].

Your Focus Score will range between 0-100, and your initial target will likely be an increase between 12 and 34 points from your baseline. For the vast majority of people, this will leave room for continued improvement in Focus Score and overall cognitive abilities as well as ADHD symptom management. While breaks are encouraged, the more you play the better the results you can expect! In general, people that finished our clinical trial with higher Focus Scores had greater improvements in real-world symptoms…encouragement to keep going!

No, it does not mean you no longer have ADHD. Instead, our clinical data demonstrate that a target improvement in Focus Score was associated with meaningful improvements in ADHD-related symptoms at the end of six weeks of treatment.

Research shows that treating ADHD with multiple strategies at once leads to greater symptom relief. You’re developing a better cognitive foundation with EndeavorOTC, which will make you more effective at managing ADHD symptoms in your daily life. Even if other strategies may not have worked before, once you have measurable progress in your Focus Score, you may have better success with other symptom management options. Keep an eye out for evidence-based tips and strategies for managing ADHD symptoms in between missions and through EndeavorOTC support channels.

Customers provided feedback that the Free Trial was important to understand if the product would work. Unfortunately, 7 days is not enough time with the EndeavorOTC treatment to assess whether it works on attention improvement. A minimum treatment course of 6 weeks is needed before progress should be fully assessed (some users may see improvement before 6 weeks) so we have introduced the money back promise as a means of offering users enough time with the product to determine whether the product is right for them.

We know results matter. And, we know EndeavorOTC is an effective treatment for attention and focus. If you play EndeavorOTC for 6 weeks, at least 70 minutes each week, and don’t see improvements in your attention, we will give you your money back as long as you meet the eligibility criteria and timeline described in the program terms and conditions.
