Thank you! ### 4/5 — Ottima applicazione *2022-03-01, version 58* Molto utile e carina anche l’idea della foto, ma sarebbe utile uno spazio più ampio per le note per scrivere qualche notizia anamnestica fondamentale ### 2/5 — Falta atualização para correção dos erros *2021-08-08* Preciso teclar com força nos números do aplicativo para entrar os números. Isso acontece somente o aplicatico ### 5/5 — Best OB wheel I’ve found *2020-11-12, version 50* I’m an MFM who uses this wheel several times a day. Easily the fastest way and most flexible app I’ve used. ### 5/5 — Top Notch *2020-10-23, version 50* Great app, can find dates either by LMP or scan to check gestation. Use all the time ### 5/5 — Love it *2020-09-09, version 50* Could not work without it... midwife ### 5/5 — Very Helpful *2020-07-20, version 50* This app fills in the gaps for me ALL the time. Can’t live without it ### 5/5 — Midwife *2020-06-01, version 50* I use this app at work every day. It’s very accurate and makes my life easy. ### 5/5 — Great app, some suggestions *2020-05-01, version 50* Excellent app. Love it. Would love if there are more fields for infant info, apgars and weight. ### 4/5 — Nice OB wheel app *2020-04-09, version 50* This app is quite useful. I like that you can save clients’ information and that the developer implemented a suggestion about highlighting today’s date. One problem I face is that you are not able to adjust cycle length. Most of the women I care for do not have 28day cycles. This can drastically change EDD. In order to take their cycle length into account I have to fudge LMP. I dislike having different dates for LMP in this app compared to their chart. ### 5/5 — Love *2019-10-14, version 50* Love this app! As a L&D RN for many years, this app gives me a quick and accurate info! ### 4/5 — ACOG *2019-05-24, version 47* I LOVE this app. However, I do believe that the dating for the trimesters is off. I’m only ever interested in the end of the first trimester and ACOG states that the first trimester ends at 13weeks 6days. This app does not calculate accordingly. Can you please look into this and make a correction if there is a consensus? ### 3/5 — Dúvida *2019-04-10* Boa noite. Acabei de baixar o App. Esse salva as informações de idade gestacional de varias mulheres para se salvar como uma agenda ( ou profissional que trabalha na área) ou só a versão tracker ? ### 5/5 — On wheel *2019-02-19, version 46* It is the best and I have been doing this for since 1980🧐 ### 5/5 — Wrong EDC *2019-02-19* The EDC is being calculated in 41th week. It’s wrong EDC is on the 40th week. Please fix it! **Developer response:** I’m not sure what you’re seeing that makes you conclude the EDC is wrong. Please email me (evan@regularrateandrhythm.com) so we can discuss. ### 2/5 — NÃO ESTÁ ABRINDO HÁ 2 dias *2019-02-19* Preciso de uma SOLUÇÃO urgente, estou sem informação de todas as minhas pacientes há 2 dias ## Most critical reviews (10 lowest-rated) ### 1/5 — Duas cobranças *2023-03-14* O App para registro é necessário realizar um upgrade de R$27,90. Se a 1ª versão fosse gratuita ok, o problema que o que você paga por 10,00 é apenas para ver a data não pode deixar nada salvo. Para que serve então? ### 1/5 — rip off to force you to pay more *2021-11-27, version 58* they make a sound as if the $1.99 you pay is going to open up the advanced options only to find out that once you pay the money and use the app that you will need to pay an additional 4.99 for the full features described. The basic features that you get for the $1.99 are free from many websites and several other free apps that actually include the ability to save your due date etc. don’t waste your money if you want the simple information provided in the $1.99 app get it free from the American College of obstetrics and gynecology app or many others. Shame on you. I just added an edit here because I found out that the American College of obstetrics and gynecology disagrees with the dating criteria utilized here and the trimester dating is off. So not only are you paying 1.99 you’re actually getting the wrong information. by the way I am a board-certified OB/GYN ### 1/5 — 51-й апдейт очень некачественный. *2021-09-11* Не настраивается и не отображается корректно темная тема!! ### 1/5 — Bug após a última atualização *2019-02-18* O aplicativo eh ótimo. Mas deu bug depois da última atualização e não abre. **Developer response:** Please update to the new version (46) which was released Monday 2/18. It will fix this issue which was accidentally created with version 45 released the day prior Sunday 2/17. ### 1/5 — Not working after last update!!! *2019-02-18* Don’t open on IOS 12.1.4 after last update on this Sunday!!! **Developer response:** Please update to the new version (46) which was released earlier today (Monday). It will fix this issue which was accidentally created with version 45 released yesterday (Sunday 2/17). ### 1/5 — Caspita!!! *2019-02-18, version 45* Ottimo nemico del buono! Quindi ultimo aggiornamento fallimentare. Crusha sempre ! Vi prego di rimediare sollecitamente. Grazie ### 1/5 — App stopped opening *2019-02-17, version 45* Can’t open the app- please fix ### 1/5 — Stopped working after update 45 *2019-02-17, version 45* When I tape the app it opens then immediately closes. ### 1/5 — What wheel *2015-05-09, version 39* Last update and it disappeared from my phone! ### 1/5 — Crashing!! *2014-10-06, version 37* Wa working perfect till Past few days ,not opening,crashes immediately .fix pls ## Most praised reviews (10 highest-rated) ### 5/5 — Ótimo *2026-05-15* Ótimo ### 5/5 — Great app! *2026-03-10, version 58* I love this app. It’s easy to use. ### 5/5 — Extremely helpful *2024-08-23, version 58* I am a nurse in a prenatal clinic and use this multiple times a day.
