Excellent. I have it four stars. Here is why: sometimes features don’t work (too many details to explain here), it needs to be tested and updated regularly. Otherwise, better for users to just use the cylcleprogo website. ### 2/5 — PLEASE CREATE TOUCH ID & get rid of terms each time *2022-01-24, version 5.0.2* Please create Touch ID so we can log in faster & please stop making us agree to terms everytime we log into the app. ### 1/5 — App just lost 1/3 of my charting *2021-06-17, version 5.0.2* App constantly forgets my login info even though I repeatedly tell it to remember. Can’t load data half the time. Doesn’t automatically determine cycle. I wish I hadn’t wasted three months charting with this app. ### 2/5 — It was working *2019-10-21, version 5.0.2* I don’t like having to pay a monthly fee. I got this app thinking it was free and you had a choice to upgrade. Today I can’t chart anything. It tells me the subscription has expired and erases my data for this day. I started using this app in July and while it took some getting used to appeared to work for what I need. Now I can’t use the chart and every time I touch something I’m told to subscribe. I wouldn’t mind a one time fee, but not monthly. I’m now looking for another app ### 2/5 — Would be great *2019-06-13, version 5.0.2* I want to love this ap, because it would save me from handwriting my fertility info, BUT even though I paid for a subscription, 75% of the time I try to record anything it pops up a warning telling me I don’t have an active subscription, and it won’t save any of my info. So, I keep trying everyday until I finally get logged in, and then I back-record for the previous days where my log-in failed. It’s frustrating. I’ve used this for multiple years, and I never had this problem until recently (last 6 months or so). Would be a great ap if I wasn’t trying to record time-sensitive data. ### 2/5 — Great NFP charting, bad design *2019-02-08, version 5.0.1* Love the method, but the interface is weird and the new color scheme is hot garbage. I’ve seen this trend happening across several apps and I don’t like it. It’s very hard on the eyes, especially with white text on these colors. Too many relatively important features also have difficult to read gray text. If this doesn’t get any better I’ll go back to just charting on paper soon. ### 4/5 — Go back to the softer colors, too much for waking eyes *2019-02-05, version 5.0.1* I’ve been a dedicated user for about four years now, so I don’t need to really describe how much I like this app. The new bright colors on the interface, even for the dark setting, are too bright for reading in the dark. The dark setting is black and bright white, so while I’m trying to read the little bitty regular font text with a black background, next to bold font on a bright white buttons, I got an instant headache! We are taking waking temperatures, this is too much for my waking eyes. —find a way to integrate individual day reports in the chart interface. Too many clicks to adjust a day. Very menu heavy. Other than that, EXCELLENT APP, just use softer colors that don’t contrast to much! ### 3/5 — Bug fix desperately needed *2018-05-22, version 4.1.1* The app NEVER remembers my login info. This makes it frustrating to use. Would love to see it fixed! ### 2/5 — Charges a lot after a few months *2018-05-21, version 4.1.1* Was pretty good until they wanted an arm and a leg subscription. Menstrual observations are only spotting, light, and heavy. ### 2/5 — Clunky and not free *2017-06-19, version 4.0.7* I'm sure the functionality of the app is fine but the user interface is clunky and frankly hard to look at. It also could be simplified so that you didn't have to click around as much. It needs some TLC from a good graphics designer to try and bring it near the UI of the GLOW app. All this makes it hard to plop down the $35/yr they want for you to get any real use out of the app. I think a better pricing model would be to just charge $5.99 or whatever for the app and forget the subscription service. I think they'd generate more revenue that way. ## Frequently asked questions about CycleProGo ### What is CycleProGo?
