This is the only biorhythm app in the Apple Store that looks great on an Apple Watch.For some reason, most biorhythm apps display poorly on the Apple Watch (in the apps themselves and in the watch face complications). Either it’s done by only displaying a set of confusing numbers, or the graphics are simply hard to see and decipher. Not the case with this app!Not only is the information displayed clearly (thick, easy to see lines) in the app but there is also a well thought out watch complication option that enables you to display your biorhythm in an innovative circular graph. What a unique way to get a quick, at a glance understanding of where your biorhythms are! I’ve been interested in biorhythms for decades and really appreciate that this developer has created something new (that I’ve never seen before) in the way biorhythms can be displayed. Quick support too…When I noticed a small glitch in the app and informed the developer about it, they responded THAT DAY and told me it would be corrected within in a day or two. Impressive!
