It is stuck on that date and will not highlight any other date. There is no provided way to update it. It still provides the cycles. Thank goodness it has the dates on the bottom because it opens to the stuck highlighted date and I have to search for current date. ### 3/5 — It works, but very basic *2016-03-03, version 1.5* The app does work okay on my devices, but it seems to ignore your locale. I think it uses UTC for determining the date, which means that its concept of "today" is based on a different time zone. I wish it would detect the correct time zone or at least let me set the UTC offset. I also wish that I could change the date format, instead of "dd.mm ddd". Example: "03.03 Thu" for March 3, 2016. ## Most critical reviews (10 lowest-rated) ### 1/5 — No Coherence *2023-03-09, version 2.0.1* I have Biorhythm on both my iPhone and iPad. Same birthday on each but biorhythms are as different as night and day. Seems as there is no science behind this app!!! ### 1/5 — Disappointing *2023-03-03, version 2.0.1* I downloaded the free version but am very disappointed and will not pay to upgrade. I tried to edit the date but all the other options were greyed out so I couldn’t have a date of birth other than today’s date eg 3rd March 2023 ### 1/5 — Not a good start! *2023-01-29, version 2.0.1* I downloaded as it looked an interesting app and was asked to put in DOB. Unfortunately, every time I put it in it defaulted to todays date. After several tried, I gave up. ### 1/5 — Rubbish *2020-04-28, version 2.0* Useless. Couldn’t even enter date of birth. ### 1/5 — Not very useful time waster *2019-11-04, version 2.0* Only for people with a good knowledge of biorhythms that can do their own interpretations. No search facility means loads of finger work. No interpretations at all. Very basic. ### 1/5 — Calendar error? *2018-05-15, version 1.5* It’s always 1 day late. ### 1/5 — Current dates not correct nor time *2015-07-12* Sorry guys a fail from me. No info on biorhythms or anything, just a chart which anyone can do. Too many ads. No options ### 2/5 — Needs more explanation *2022-12-08, version 2.0.1* Needs more explanation on how to use and benefit from the app. ### 2/5 — Error in calendar *2015-05-09, version 1.4* App shows wrong date when viewing biorhythm chart. ### 2/5 — Latest version forces audio ads *2015-04-14, version 1.4* Upon launching the latest version an ad for Game of War plays with volume turned up. Displaying a static page is one thing. Forcing a loud audio-video clip is something else. Now uninstalling; recommend you do the same. ## Most praised reviews (10 highest-rated) ### 5/5 — Very exact *2026-01-20, version 2.0.1* Tremendously precise...differs a lot from the classical...it makes you wonder why!! ### 5/5 — Muy útil !! *2021-08-09, version 2.0.1* Lo ha usado mucho a través de los años. Altamente recomendable. ### 5/5 — Uncannily accurate! *2020-05-31, version 2.0* Anyone who feels ‘Moon-centric’ could benefit from this app in respect to their lifestyle. ### 5/5 — DIYMBE *2019-04-09, version 2.0* I have studied biorhythms for over 40 years and find this app very useful ### 5/5 — good but no zoom on this *2018-12-28, version 2.0* Pretty good app, does what it says and nicely executed. Simple with no unnecessary extras. Excellent implementation of the composite wave underneath in a sub window. But would be great if could zoom out and see a whole year, for example, so only 4 stars. ### 5/5 — Great App *2017-11-06, version 1.5* Great App, quick to read and very clear. ### 5/5 — Best!! *2017-10-25, version 1.5* Best biorythym app I've found!!!! The adjusted version is extremely accurate, while classical ones are not.....highly recommend! ### 4/5 — Rec *2024-01-08* Love this app for several years ### 4/5 — Mr *2017-06-01, version 1.5* Had to give it 4 stars, otherwise it will not accept the review, this app does not work! ### 3/5 — Nice App, but... *2016-11-14, version 1.5* The app's current day calculation is a day behind and there isn't a way to update it 😒 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
