User reviews

Helpful app!

This app has been very useful in allowing me to track my sleep patterns. I find it easy to use, I would recommend to anyone who wants to form a habit of recording their sleep times.

Not user friendly

This is the most clonky app I’ve come across in a long time. Isn’t allowing me to click on today to add wake time/naps. Isn’t allowing me to edit yesterday or view the data. Isn’t allowing me to delete yesterday to start again.
Save button is not working when I add text.
When I try to add text it jumps to the beginning of the text when I start typing.
When the save button does work, it deletes the text I’ve just added. Buggy as heck.
I’ve already deleted the entire diary once and not inclined to do so again.

Shows inaccurate sleep times.

This is what I’ve been told to use by the hospital! Methinks an update is long overdue. C’mon Pharma, please keep up!

It’s ok but data sharing is limited

The app is ok but when I try to share the data with the relevant professionals it the report doesn’t show the additional comments I have added on to each daily record

Good, but with a pretty critical bug

Generally pretty good, been useful in helping me track my sleep and the user interface is pretty nice. Unfortunately as the other reviewer mentioned, seems to regularly add 24 hours to my total hours sleep for the night. Not always, but regularly enough that it’s making it hard to keep using the app. Unclear what the pattern is, but it is frustrating.

Useless.

Constantly returns the wrong amount of sleep. Needs the function to add dates to the times in order to work properly otherwise the sleep is regularly overstated by 24 hours.

I guarantee I have never slept for 31 or more hours at a time and yet the app shows I've done this 5 days in a row.
