Are you concerned about your child’s or student’s social skills or development? Think Autism® is a rapid screening tool that gets you the answers you need to take action. Complete our validated 15-question Social Challenges Screening Questionnaire for your child or student and receive immediate results that will indicate if a formal evaluation is needed for autism spectrum disorder. Developed for parents, educators and medical professionals, Think Autism® is designed for children ages 8-13 and offers resources in all 50 states. Our Social Challenges Screening Questionnaire can identify children who may have symptoms that were once characterized as Asperger’s syndrome, but now Asperger's is part of autism spectrum disorder. These children have significant social impairments that markedly affect their functioning and overall wellbeing, but language develops on time and there is no associated cognitive impairment. The app also features informational videos from the unique perspectives of professionals in the field, a parent, and a person with Asperger’s. If more individual support is needed, you will have the option to connect with an expert at Southwest Autism Research & Resource Center located in Phoenix, Arizona. Our team will guide you through your next steps and connect you to resources in your area. Get started by downloading our app for free. Southwest Autism Research & Resource Center (SARRC) is a non-profit, community-based organization dedicated to autism research, education, and resources for people with autism and their families.

Canvas Dx is for prescription use only. To find a prescriber go to cognoa.com or email support@cognoa.com. Canvas Dx is the first and only FDA-authorized Software as a Medical Device (SaMD) that aids physicians in diagnosing autism spectrum disorder (ASD) in young children. Canvas Dx harnesses clinically validated artificial intelligence (AI) technology to aid physicians in diagnosing ASD in children between the ages 18-72 months who are at risk of developmental delay. Canvas Dx incorporates 3 separate, user-friendly inputs: 1. A parent/caregiver questionnaire that asks about the child’s behavior and development collected via a parent/caregiver-facing app 2. A questionnaire completed by video analysts who review two videos of the child recorded by the parents/caregivers 3. An HCP questionnaire completed by a physician who meets with the child and a parent/caregiver, collected via a healthcare provider portal The Canvas Dx algorithm evaluates all 3 inputs, generating a device output for the prescribing physician to utilize in combination with their clinical judgment. Canvas Dx is not intended for use as a stand-alone diagnostic device but as an adjunct to the diagnostic process. CONTACT: Email: support@cognoa.com Indications for Use Canvas Dx is intended for use by healthcare providers as an aid in the diagnosis of autism spectrum disorder (ASD) for patients ages 18 months through 72 months who are at risk for developmental delay based on concerns of a parent, caregiver, or healthcare provider. The device is not intended for use as a stand-alone diagnostic device but as an adjunct to the diagnostic process. The device is for prescription use only (Rx only). Contraindications There are no contraindications to using Canvas Dx. Precautions, Warnings The Device is intended for use by healthcare professionals trained and qualified to interpret the results of a behavioral assessment examination and to diagnose ASD. The Device is intended for use in conjunction with patient history, clinical observations, and other clinical evidence the HCP determines are necessary before making clinical decisions. For instance, additional standardized testing may be sought to confirm the Device output, especially when the Device result is not Positive or Negative for ASD. Canvas Dx is intended for patients with caregivers who have functional English capability (8th grade reading level or above) and have access to a compatible smartphone with an internet connection in the home environment. The Device may give unreliable results if used in patients with other conditions that would have excluded them from the clinical study. Among those conditions are the following: • Suspected auditory or visual hallucinations or with prior diagnosis of childhood onset schizophrenia • Known deafness or blindness • Known physical impairment affecting their ability to use their hands • Major dysmorphic features or prenatal exposure to teratogens such as fetal alcohol syndrome • History or diagnosis of genetic conditions (such as Rett syndrome or Fragile X) • Microcephaly • History or prior diagnosis of epilepsy or seizures • History of or suspected neglect • History of brain defect injury or insult requiring interventions such as surgery or chronic medication The Device evaluation should be completed within 60 days of the time it is prescribed because neurodevelopmental milestones change rapidly in the indicated age group.

Verdict
The clearest difference is rating: Canvas Dx at 4.5 against ThinkAutism's 4.0. Canvas Dx also leads on update cadence (every 3 months vs every 21 months). ThinkAutism's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, ratings volume and in-app purchases there is nothing between them.
