LIFESPACE Research
Read full descriptionHide full description
The LIFESPACE study is following a group of healthy older adults without clinical impairment to see whether their everyday behaviors can provide very early warning signs of Alzheimer’s disease. Researchers will use this application to track where participants go in their communities, and how active and socially engaged they are. By combining these “digital tracers” of daily life with health and environmental data, the team hopes to identify patterns that signal a higher risk of dementia long before noticeable memory problems emerge. In the long run, this could make it easier and cheaper to detect who is at risk and intervene earlier to help protect brain health.

Verdict
The clearest difference is in-app purchases: LIFESPACE Research at none against AOJ+'s 10. LIFESPACE Research also leads on update cadence (fortnightly vs every 5 weeks). AOJ+'s advantage is device support (4 vs 2). On price, ads and iOS requirement there is nothing between them.
