Almost Perfect

I've used this app for yeeeeears and it's never let me down. I love its simplicity, the cute little widget that thankfully doesn't scream "period tracker", and that I have the flexibility to choose "average" for period length while also choosing a custom, fixed number for cycle length, and that I was able to use it for all these years without once feeling like I needed to pay for the extras (notifications, additional themes) and NEVER being prompted to do so. I finally decided to buy the extras today for the simple fact that I've been using and loving the app for so long for free that I owed the developers 😂 The ONLY complaint I have is that it doesn't auto-sync with the Apple Health app. That's actually where I input data about my period because I can add additional info like symptoms (I just love the widget from this app and I like having two trackers because they calculate slightly differently), and I'm so thankful there's a manual sync, I just wish it did it automatically.

Cute, simple, very useful little app

I was thinking how useful it would be to have a reminder, then realized I hadn’t checked for it. Three dollars gets you day, a few days before, a few more days before and a week heads up, and similar ones for ovulation and fertility, as well as predictions. It’s discrete and visual, and to put in a new period, you just click a button. You can also look back in a little list of your periods and their lengths, above which is a circle representing your cycle with a little blue cube indicating where you are, and a six month view showing the current month, two months previous, and projection for the next three. And again it’s super cute but also in a very neutral way that can appeal to almost anyone - a little white cube with eyes, a bunch of tiny cubes that organize themselves into the number of the day you’re on, a bluer-teal, white and grey color scheme that makes me feel like my cycle is pretty chill after all, and nothing to sweat about. I never write reviews. Worth every penny.

Simple but Good

Very simplistic and minimal design, a great app if you don’t care about when you are most fertile. The widget is also very discreet, if someone was to go through your phone, the widget just looks like some countdown to an event and it gives no indication about it being your period cycle.

My only recommendation would be to add a symptoms tracker, I think the app would benefit from that. Also I’d like to be able to move the little animals on the screen. I keep trying to move them around individually because they look like they could move, but that’s just me.
