10 Tips for Best Flo Experience

Hi there, We are Hanna and Nadia, your 24/7 support buddies. We LOVE getting your feedback! To make your experience with Flo flawless, we are launching a regular monthly column, where we’ll discuss your most urgent and frequent questions. Ready? Go!

1. How do predictions work?
Flo gives predictions about your ovulation and fertile days based on your cycle data (all the information you enter into the app, including past periods and symptoms). Fertile days are marked in blue colour. The day that is inside a blue dotted circle is your ovulation day – and it says “high chance of getting pregnant”. Days before ovulation and a couple of days after are those with “a chance to get pregnant” (the app considers various parameters – such as the ability of sperm to live for up to 5 days in a woman’s body, the ability of your egg to live for one day – and it tries to keep the fertile window as wide as possible to include all possibilities). The days that are black (after the ovulation and before the next period) have a low chance of pregnancy.

2. How can Flo help me get pregnant?

If you wish to get pregnant, sex should take place close to your ovulation or during it. In our app blue days represent your fertile window – the time when pregnancy is possible. The day encircled in a blue dotted line represents your ovulation, and when ovulation begins you have the highest possibility to get pregnant. Our app calculates the probability of ovulation based on very complicated algorithms. The more cycle data you enter, the more accurate predictions the app will give you. For better results, you can track your basal body temperature, cervical mucus and log ovulation test results to pinpoint ovulation.

3. How do I log my period?
In order to log the period start date, please press the red button called “Log Period” for the required day on the main screen, and this day will be added to your period cycle. The last day logged will be considered as your finish date. If you wish to edit the period, please tap on the name of the month and press “Edit Period Dates” > then check the required dates and save it.

4. Can Flo tell me when my safe days arrive?

Unfortunately there are no completely safe days in our cycle. Flo can say whether the chance of getting pregnant is high or low on a particular day – yet “low chance of getting pregnant” means that the possibility of getting pregnant still exists. The human body is a complex system, each of us is unique. Many factors influence your cycle including sudden hormonal imbalance, illness, medications, over-exercising, diet change, stress, sudden weight gain or loss, and even travelling. And this is why there is no a 100% guarantee. If you don’t plan your pregnancy yet, we’d suggest protected sex only.

5. I can see that it’s possible to track my physical activity and nutrition in Flo. How do I enter this information?
There are 2 ways of getting your step data and distance in Flo: 1) Either from your phone device directly, through a built-in pedometer; 2) Through an app called Health App/Google Fit, which can take the steps either from your phone or other trackers attached (you can connect Health App/Google Fit in Menu > More settings > The Health App/ Google Fit > Connect and follow the instructions). Nutrition data can only be imported from other trackers via Health/Google Fit (see above).

6. Can I back up my data?
Yes, get registered with Flo (this can be done in Menu > Profile > Save Data) then your data will be safely stored on our side. You’ll always be able to restore it if you switch to other device.

7. I requested password reset, but the email didn’t arrive. What should I do?
If you didn’t receive a password reset email from us, it could be that you never registered your Flo account before. However, there is a chance of restoring your data if you still have access to the device that you originally installed Flo on, and it has not been reset. If these conditions are met, please open Flo on it, and instead of logging via the “Restore Data” button, press “New User” and then contact the support directly from the app. We will help you to restore the data.

8. What if I wish to change my email address, merge my accounts or delete them?
This can be done on our side only, so contact us right from the app and we’ll assist you.

9. I miss certain features in Flo, can I send you my requirements?

Absolutely! We love to hear from our users and listen to your needs. We are constantly working on improving our app, and carefully review all ideas that arrive. If you miss any of the features, lifestyle or pregnancy symptoms, let us know. So don’t hesitate to get in touch!

10. What is the best way to reach out to you?
The optimal way of contacting us is via the Flo app itself. Just tap “Contact support” from the app’s menu and send us a message. Please leave the rows of symbols in the message body intact – it’ll help us identify your account and provide necessary assistance.

  • Such an intuitive app! Hannah Malone
    I’ve tried several period tracker apps on the market and nothing is as good as Flo. It’s accurate, detailed providing you with an abundance of parameters to log, and they even provide useful articles and surveys to help you better understand the complex nature of the female body.
  • So accurate Connie Joseph
    I use this app to track my period and symptoms and it’s so accurate. I tried a few other apps before this one and they were never so accurate and didn’t have as many tools to use.
