Are you noticing changes in memory or thinking in yourself or someone you care about? ALz Test is a brief cognitive self-check designed to help people decide whether changes in their memory or thinking should be discussed with a qualified healthcare professional. The app presents a 15-question picture-based test covering memory, visuospatial skills, and cognition. Your responses are used to provide a result that may help you decide whether to continue monitoring or discuss concerns with a healthcare professional. ALz Test can be used over time as part of monitoring your memory and thinking. It is intended for informational and self-check purposes only. ALz Test does not diagnose Alzheimer’s disease, dementia, cognitive impairment, or any other medical condition, and it is not a substitute for evaluation by a qualified healthcare professional. If you or a loved one are experiencing memory changes, confusion, difficulty with orientation, or other cognitive concerns, please contact a doctor promptly.

Verdict
The clearest difference is in-app purchases: BioCog at none against Alz Test's 3. BioCog also leads on update cadence (monthly vs every 3 months). Alz Test's advantage is iOS requirement (13.0 vs 17.6). On price, ads and device support there is nothing between them.
