OBJECTIVE, SPECIFICATION AND SUMMARY

Cycle Manager Page 5 of 8

1.1 OBJECTIVE

Cycle Manager is a mobile app that is based on the Billings Method. Imagine a method of

family planning that is simple, natural, harmless, 99.9% effective, beneficial to

communication within a monogamous relationship, and in keeping with one's relationship

with God. That is what The Billings Method offers. It is a method that will not harm a

woman's future fertility, and will help a woman determine when she is fertile (great for

couples having trouble conceiving). It is also an invaluable and drug-free way to avoid

pregnancy. In fact, it is a method that works. The Billings Method does require discipline

and diligence, especially in the beginning, but eventually it becomes second nature.

Cycle Manager is an app designed to help every woman implement the Billings Method

effectively. For years, implementing the Billings Method has been cumbersome for most

women in the sense that it has been done mainly on paper – diaries, calendars, menstrual

charts etc. Cycle Manager has changed all that as women would now have to chart their daily

body signs on their mobile devices, thereby eliminating the inconveniences of having to chart

on paper. Above all, Cycle Manger has additional and interesting features that make charting

easy and fun.

As of now, the app design for the Android®

platform has been concluded: it can be installed

in Android devices of version 4.1 (API 16, Jelly Bean) and above. However, release of this

app will only be done when the respective designs for the Windows® and IOS

® platforms

have been concluded.

Embedded Systems Design, Java SE SDK, Android SDK, Digital Logic Techniques, XML,

SQL etc.

1.2 SPECIFICATION

Cycle Manager mobile app was designed to help every woman implement the Billings

Method effectively. This is a simple, natural and drug-free way to determine when one is

fertile or not. An internet connection is not required to use the app: all daily charting records

are saved in a specially compressed file within the mobile device. This app encompasses

more than a mere menstrual calendar as it is enriched with interesting features and one of the

key essences of the app is user friendliness. Consequently, incorporating these rich features

was inspired by the following specifications:

APP MUST BE AS SMART AS POSSIBLE

a) Users should input just little information for charting: that is only as much information as

it is necessary; while the app must deduce the rest of the required information.

b) It must take less than one minute duration for a user to save a chart record, this duration

being the time period starting from when the user commences data input and when data is

eventually saved.

DAILY CHARTING SHOULD BE EASY

c) For daily chartings, users do not have to start the app themselves and users do not have to

remember about the app: the app must be able to start automatically every day at a time

pre-set by the user or at a default time if the user has not yet set a time for daily charting.

d) Even when the device has been turned off, the app must be able to re-establish the pre-set

time for daily charting (or the default time if there is no pre-set time yet) upon the next

device booting.

NEXT BEGINNING OF MENSTRUATION MUST BE DEDUCED WELL IN

ADVANCE

e) So as to be adequately prepared well ahead of time, the app must be able to deduce and

furnish users with a projected date of the beginning of their next menstruation. This

projected date information must be available as from the day the user charts in the current

menstrual occurrence.

f) Once a projected date of the next menstruation has been provided, users should be able to

choose whether or not to set a menstruation reminder alarm based on the projected date.

HISTORICAL INFORMATION SHOULD EASILY BE ACCESSIBLE

g) Historical data (saved charting records) must be easily accessible and should be presented

to the user once the app opens. The most recently saved ones should be presented firstly.

h) Saved data must be accessible either sequentially or randomly in accordance with users’

choice.

IMPORTANT STATISTICAL INFORMATION MUST BE DEDUCED

i) Based on historical data (save charting records), users should be able to deduce important

statistical data, especially those frequently demanded for by gyneacologists.

Consequently, within pre-set dates users must be able to obtain the following statistical

information from the app:

Frequency of sexual activities.

Frequency of visitations to the doctor.

Furthermore, within a pre-set period, the last date of occurrence of each of the cycle

states (these cycle states are outlined by the Billings Method) must be made available

by the app.

THE APP MUST BE ABLE TO BACK UP SAVED RECORDS

j) User should be able to back-up her historical data (saved charting records) anytime by

exporting the data to a text file format.

APP MUST INCORPORATE A HELP SECTION

k) The help section of the app must contain invaluable literatures on each of the cycle states

as well as a quick start guide on how to use the app. All menu items in the app must be

thoroughly explained in simple language in this section.

1.3 SUMMARY

Presently, the app design for the Android® platform has been concluded: it can be installed in

Android devices of version 4.1 (API 16, Jelly Bean) and above. However, release of this app

will only be done when the respective designs for the Windows®

and IOS® platforms have

been concluded.

2.1 CLASSES

In all, seventeen (17) Java classes (totaling over 7500 lines of Java code) were developed for

this app and they encompass all aspects of the app: the screens, user-interfaces, multimedia

items, database connection, menu items and their functionalities etc.
