Perhaps Add Activity Log and Post day end of day Review ?

I love this app! I just think perhaps adding a way to log activity so you can see exactly how long it’s been since the triggering activity, as well as adding a way to do your end of day logs after 12 am. I have a weird schedule due to my husband working night shift and I constantly miss logging the end of day report due to this.

Love being able to track my chronic illness

I love how it lets you add a start of the day and suggests pacing point and lets you adjust if you have more or lower energy

Very helpful

I've tried several different apps to managing my energy consumption and daily activities that are impacting PEM and sudden crashes. Fatigue Sense gives real time data and helps you to visually see where you are in your day. The reason for taking a star away, there is a lot of daily entry requirements and sometimes I'm too tired or I forget. I understand this is going to be updated to make things easier on the users end within a few weeks. Overall, excellent data and the most helpful in planning your energy expenditure for the day.

Excellent, informative and helpful

The team is committed to the community. They update and evolve the app based on community feedback. I'm getting better input on when to slow down

best free app for pacing!

the app seems new and is actively being updated but considering its free provides a really detailed analysis of the data it tracks that even after only 2 weeks has been really helpful for pacing and noting potential triggers and patterns! excited for it’s continued development
