## What is billingsMentor®?

billingsMentor® guides you in observing, recording and interpreting your fertility symptoms according to the Billings Method. It can be used to achieve or avoid pregnancy. Cycles do not have to be regular. It helps you to follow the Billings Method by: 
• guiding you in making a proper recording of your fertility symptoms;
• automatically generating your fertility chart;
• interpreting your symptoms and your fertility status on each day;
• recognizing your Peak day in a cycle and predicting menstruation;
• allowing you to override and mark your Peak day in a cycle;
• identifying your Basic Infertile Pattern (BIP) whether you are having normal cycles or long cycles (e.g. breastfeeding);
• allowing you to override and define your Basic Infertile Pattern (BIP);
• applying the 1,2,3 count of the rule concerning a change from the BIP before the Peak day;
• reminding you of the wait day after intercourse during the pre-Peak phase.

The underlying fertility interpreter (Ovulation Mentor) is ranked the most accurate of all fertility awareness apps analyzed in this study:  http://www.jabfm.org/content/29/4/508.full.pdf+html

English, Spanish, French, Portuguese, Russian, Chinese and Arabic versions are contained in the one download.

billingsMentor® avoids the use of stamps and symbols in the fertility chart by visualising fertility as a simple bar chart that combines fertility with the rules of the Billings Method. This format is intuitive for the new user. There is an option to use the traditional stamp or symbol format if desired.

Tablet users: Users should consider using the web interface from tablets (see below).

billingsMentor® is also available as a web service. All data, whether submitted from mobile, tablet or desktop is stored on the billingsMentor® server. Thus your current fertility chart is always available from mobile or internet and is recoverable in the case of a lost or stolen phone.

When you begin to use the service, you make a privacy agreement.

Reference: The Billings Method, by Dr Evelyn Billings and Dr Ann Westmore, Penguin Books, first published 1980, new edition 2011.

### 1/5 — Archaic

*2025-03-31*

It feels like 1980 ….very difficult to use !

### 1/5 — Overwhelmingly Frustrating to understand

*2021-12-12, version 4.3*

I have tried to use this app any time, and each time I give up in frustration! It is not clear in how to use the app and it confusing? Athletically it frustrating trying to navigate and, what should be a VERY SIMPLE chart and symboled system, is turned in to a complicated muddle, ever time I try to even figure out what I am supposed to do! I even tried emailing support from the app, for help, but the email section would not let me see my typing or submit. I regret spending my money on this! PLEASE BILLINGS METHOD, please redo this app! I would gladly spend money on something that HELPED!!! This was ONLY an frustrating experience!

### 1/5 — Faire aussi mauvais relève de l’exploit

*2020-07-10*

Appli sensée être en français... le développeur doit être dys.. je lis de l’espagnol !? Visuellement, l’application est dépassée, technologiquement vendre une appli 5 euros qui ne s’adapte pas à la taille de l’écran... des gratuites le font.
Quand à Billings, ce n’est déjà pas simple, ici on pousse le vice à le compliquer...
Manquerait plus que des pubs et on aurait une pépite.

### 1/5 — Terrible

*2019-10-21, version 3.1.4*

Terrible interface. Almost impossible to use/ understand

### 1/5 — Useless.!

*2019-05-18*

Nothing works - I can’t access the help section or send a message to ask for help. Complete waste of money.

### 1/5 — L’appli ne fonctionne pas

*2019-04-03*

Dommage car il n’en existe pas d’autre. 
A fonctionné une semaine puis toutes les données enregistrées ont été perdues sans moyen de les récupérer. 5,49 pour rien.

### 1/5 — Cheio de erros de funcionamento

*2018-08-30*

Cheio de links quebrados, páginas não traduzidas para o português e informações conflitantes.

### 1/5 — Can't use it

*2017-08-01*

### 1/5 — Not reliable

*2016-04-03*

Long and painful Connexion process ; app not reliable. 5 dollars for nothing....
A pity bc could be very helpful if it worked well
