Won't sync to Google Fit I would like to see graphs and reports for the parameters as well. It's kind of annoying having to go to every day individually to see when I tend to get acne flares, when I had s(e)x, when I get cranky, moody, cramps, etc. It shouldn't be difficult to add as you already have the information. You just have to add so it gathers the info into graphs. I just don't see the point of including the parameters when it's not easy to check for patterns.

i love this app. its relatively simple to use, and is surprisingly accurate. i find that its almost never off, and if it is, it's only by a day or two. also, if you change devices, say, a new phone, as long as you log in, it'll save your past cycles for you. i like knowing when i can expect my period. the only complaint is premium. i find that there's not a lot of things one can do without premium, so thats kind if a let down. but overall, i find this app to be very useful and i recommend it.

EDITED 6/28 I've uninstalled this app to ensure my data isn't sold. The best tracker I've used yet. It's accurate and I love the additional information they provide. I've learned a few things about my cycles because of this app. There is a paid version, and based on what I'm seeing in the free version, it may be worth upgrading if you have a special health circumstance or need more targeted information that isn't accessible in the free version.

Hi there! We hear your concern. Flo will never sell your personal data, and we will soon be launching a new feature: Anonymous Mode, that removes your personal identity from your Flo account. This mode will make it so that no entity can identify you. We will be sharing more details with you in the coming weeks. Yours, Flo
