Use the calendar view to select the day that should be the first day of your cycle. Tap on the Bleeding tile and select 'Start New Cycle'. You may also have to uncheck this box on the previous first day if you originally didn't go back far enough.

You can, by using the calendar view to select a date in the past. New cycles are denoted by a checkbox in the bleeding tile. The easiest way to do this is to start with the oldest day in the past, and jump ahead by a month at a time. The days in-between will fill in for easy access later.

At present there is not a way to tell the app you are breastfeeding but when it first tells you that your period may be late, you can tell it not to remind you again. That will stop the reminders until you begin a new cycle. Stay tuned!

The Chart Neo app marks the BBT coverline and temp shift according to Sensiplan rules. If you would like to self-interpret your BBT chart in the Chart Neo app, then please note that it can be a bit different than some manual charters may be used to. First thing to understand is that temps in the Chart Neo app are always graphed in rounded Celsius.

This is how it works:

• Raw Temp from TD in C → Rounded to 0.05ºC → Converted to F → F Temp Displayed
• Raw Temp from TD in C → Rounded to 0.05ºC → C Temp Displayed

There are no rounded-in-F temps. Note: if you are using the Chart Neo app without Tempdrop, then always enter the raw F temp and not a rounded F temp.

When manually analyzing a shift, you do it by looking at the dot pattern or deviation pattern. The horizontal lines shown on the Chart Neo app chart are separated by 0.05ºC, which equals approximately 0.1ºF. This is 1 deviation or 1D. When you are looking for a temp to be 0.2ºC (approximately 0.4ºF) above the coverline, you are looking for a temp that is 4 deviations (4D) above the coverline. That means you count 4 lines above the coverline and look at that point or above to find it. This way of chart reading works for any chart displayed with a proper horizontal grid behind it, like most paper charts.

• 1D = 0.05ºC (0.1ºF) → count up 1 horizontal line
• 4D = 0.2ºC (0.4ºF) → count up 4 horizontal lines
