Partial goal achievement on multiple days	Good job for checking into the app. I know that can be hard when barriers present themselves but you are aware of what is not working. I know you are able to reach those goals you set out to achieve. You can do this!
Missed check-in for 2+ days	Hey (insert name)! Just checking in to see how it’s going! 2 days have gone by since you last checked in to the system. Every day is a new one so let’s get you back on track and start monitoring that exercise! The hardest part is checking in and keeping track of what you are doing.
