There aren't even any notification settings that I could find. App needs to be updated. The main reasons I purchased it for. ### 1/5 — Biobummer *2014-02-22, version 1.3.1* Can't download. VERY disappointed. ### 2/5 — Likes to Crash *2020-02-15, version 2.2.3* I just downloaded this app. It only displays one person, though I have 2 people entered in the app. It also likes to crash as I’m navigating through it. Not sure about this one yet. ### 2/5 — Not Sure about this *2015-01-22, version 1.5.2* I'm not sure what this is supposed to tell me. It seems to create some sin waves based on the birthdate. It loaded and ran, however, without more direction from the developer, it's useless. ### 3/5 — Hand enter every one *2021-05-01, version 2.2.3* This would be a great app if it could look at your contacts and get names and birthdays but no, you’ll need to enter each one. ### 3/5 — Was great. After updates no longer works! *2014-11-01, version 1.5.1* A really good bio chart calculator. However, after doing the requisite App Store updating, it no longer works. ( same complaint from a friend who used to use this app. What gives? Please FIX. Thanks. ### 3/5 — 73 Mb for 2D Graph app? *2014-03-16, version 1.3.1* There are amazing pieces of art in AppStore, that are below 20 Megabytes. Audiobus is 30 Mb, iFiles is 60 Mb. Other that that app is great, if you are into this thing. You can save several persons with different dates and trace their emotional, etc. states. 3 stars because it's about 10 times oversized. ### 4/5 — Nice looking! *2016-02-06, version 1.5.2* The graph shows an individual's high and low points. Not much to see here. Move along folks! ### 4/5 — Good *2015-06-13, version 1.5.2* Good app very functional and nice looking. It is a pseudoscience however and has nothing explaining suff in it so no 5 stars ## Most praised reviews (10 highest-rated) ### 5/5 — Years ago *2021-04-19, version 2.2.3* I did bio rhythms years ago. Recently I have been discouraged with how tired I have been and it came to my mind about the bio rhythms so ISaid to my daughter let’s check it out she said let’s see if there is an app so here we are I love looking at it and excepting the fact that this is where I’m at don’t be hard on myself just see where I am and deal with it. I need to educate myself more on reading it and investigating the meaning ### 5/5 — A must have app *2020-01-10, version 2.2.3* Of all the biorhythm apps I’ve tried and sifted through, I’ve found this to be the most consistent and laser accurate. Highly recommend ### 5/5 — The Best Biorhythm App! *2019-02-14, version 2.0.3* Jacek is awesome to responding and resolving an issue I was having with the widget. This biorhythm app is my favorite because of the precise details it has to offer. The widget is great as well, which it can show multiple biorhythms for many people. I use it for me and my wife. Keep up the great work! ### 5/5 — The best... *2019-01-21, version 1.8.2* Of all the Apps currently being offered in the App Store, yours is the most complete in features, well thought out, user friendly and useful! Biorthymn App written for and by a user; many thanks! Write on...VFP ### 5/5 — Love to know my cycles *2017-11-18, version 1.8.2* This app gives me my four cycles and can also compare them with my husbands cycles. A very nice compatibility feature. I was hooked on Hi-Biorhythm for years but it is not compatible with the new iOS so off with its head. ### 5/5 — Rebecca *2017-08-27, version 1.7.1* I am really enjoying this app. Easy to use and understand. Wish there was a short aid that explained what it all signifies. Have yet to find a bio-app that does that. ### 5/5 — Biorhythms 4U *2017-08-22, version 1.7.1* I've been using Biorhythm apps for many years and I have found that this is the one that I like best. There is so much customization in this and I really do appreciate that. Easy to use easy, to read and very easy to understand. As of now, I feel that this is the best by a rhythm app around. ### 5/5 — Great Biorhythm App! *2017-04-20, version 1.7.1* Biorhythms 4U is a surprisingly feature rich biorhythm viewing utility, with a lot of customization options, and a nicely designed interface. I knew in a minute that I made the right choice purchasing this, as I could immediately figure out how to use it, and it has unique features, including being able to show biorhythm data for multiple people on the screen concurrently, as well as being able to choose the color and dashed line style for each person's biorhythm. Included in the features are a "compatibility" value, where overlapping trends between multiple people can be seen graphically, or expressed as a percentage, for any day you like. The interface is very responsive. Once you have added people profiles, all it takes is a swipe across the screen to scrub through time for quick and simple plot viewing. Anyone who knows what biorhythms are will appreciate the features and design of this app, and the hands-on convenience of calling up biorhythm plots instantly. As good as the app is, there are a few feature additions that would make it even better: - The ability to print, or email a PDF export of a biorhythm plot. Provide options for exporting a week or month, to simplify printing. - A predefined database of famous people (dead or living) to instantly compare biorhythm plots. ### 5/5 — Fun to play with! *2016-06-03, version 1.5.2* Is it real? Who knows? But sure enough, both my wife's rhythms and mine were at their lowest .. and we were sick during that period! Coincidence? Easy to use and fun! ### 5/5 — One of the best app in this category *2014-10-22, version 1.5.1* Good features and nice look. Works fine in iOS7 and iOS8 on iPhone and iPad. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
