One thought is if you could work on marketing / targeted theme for people with memory issues (like from age, or illness). So perhaps explore if you can sell it as a tool to assist those with medical needs for it.
Be careful not to market as a medical device. This can come back to bite you. "My mum used this tool made for people with memory issues to tell her to remember to take her medicine and it was offline for a day and she's now in trouble".
