I forgot to log a cigarette I smoked earlier, can I log it now?

Yes, you can add a cigarette you smoked earlier in the day, or from a previous day.

To log a cigarette click the + symbol next to the cigarette icon.

There you'll be able to edit the time and reason for smoking a cigarette. For example, if you forgot to log one earlier and want to do it now, click "Edit Time"

From the next screen, you can edit the date and time of your last cigarette as seen below.

Once you have the date and time adjusted click "Done" to move on to the last step which is to select a reason for the cigarette.

Once you have the date, time and reason set correctly hit the green "Done" button and your cigarette is logged.
