I had a task that I was supposed to do by a certain date, and when I went to do it that day, it was already marked it as missed. I had a task due today, answered the questions and saved it earlier this morning, and now it says it was missed. It’s very frustrating. ### 2/5 — Buggy app *2023-01-19* The most recent update removed the app from my iPhone. I had to download again. I am iOS 16.0.2 . IPhone 12 Max Pro. In the past I have had to complete the diary multiple times, close the app, reboot and set the diary again to get completion. Required change to password pop up is the only place time to change password. If dismissed no place to complete password change at users convenience. Under funded app. ### 2/5 — Poor *2022-07-10, version 10.0* My password is my face ID, but all too frequently the hub does not allow for this. I once spoke to the Help Line, but this was in USA and was no help at all. It was my local Synexus base Which got it sorted ### 1/5 — Very poor *2022-05-06, version 9.1* Extremely poor functionality, sloppily laid out and prone to inaccurate information. This is about as badly constructed an App as I’ve come across. And now it does not even record my results when I post them, forcing me to email the study each time. Basically, this App is crap. ### 1/5 — Stupid site *2022-04-18, version 9.1* This is a most annoying site . I can’t exit when I am done! And it isn’t even ready for the day early in the morning. I am talking 6 AM eastern time . And I was told I only have to check in every 2 weeks starting today? Anyone in charge? Do you agree? How am I to know? ### 2/5 — Still a pretty poor app *2022-04-05* I’ve been using this app for nearly a year and a half. I think there been at least four or five updates during this time. I’ve noticed minor improvements, like it’s easier to login, but the app is still not very helpful to someone and participating in a trial. My key complaints: 1. Unreliable: Since the most recent update, the server used for data logging (eDiaries) is down about 50% of the time and since I currently have to log four times a day I don’t have time to retry later twice a day. 2. Unfriendly: The app provides a todo list, but doesn’t update as you complete items. Instead it seems to replace the list with a new one overnight. Except it doesn’t always do that either;I have todo’s from three weeks ago that I completed but are still on the list. ### 2/5 — Spend money on a better app *2022-03-29, version 9.0* This app has been so buggy, since the start of the trial. The trial that I’m in only uses it to record responses to the same questions every week. I can’t imagine how this could be used for more complex decentralized trial use cases. ### 1/5 — Utter Garbage *2022-03-28, version 9.0* Update: New update today! But unfortunately it is still utter trash. Supposedly you listened to the feedback. No you didn’t. Almost nothing works. Why does anyone pay you for this nonsense. Unbelievable. The prior reviewer (Zarqua) covered every thought I had very succinctly. This app could not be worse. Their support line is useless too. Sadly I can’t submit my review with zero stars!! ### 1/5 — Worst app I have seen for ages *2022-03-16, version 8.1* Used in the UK for Ensemble2 trial From the very start when it was impossible to set up, not support in UK, chat function never worked, diary reminders don't work and keeps asking me to book a new study appointment, immediately flashes that this function is no longer working in latest version and then asks me to choose a suitable date from a non existent list!! None of the supporting study documents are available. Truly an awful app. Update has just broken it, still remains worst app I have seen!! ### 1/5 — Fails *2022-03-07, version 8.1* The update doesn’t work on my iPhone, the screen doesn’t even appear when I try to enter the site ### 2/5 — Notification after ediary entry doesn’t go away *2022-03-04, version 8.0* Is there a reason why I have to enter the same ediary multiple times to get the notification to go away? ### 1/5 — I’m quitting a trail because of this app *2022-02-10, version 8.0* I can’t begin to tell you how rubbish this app is. After a year or so of becoming stressed out with putting in my Jansenn ensemble 2 results I can’t do it any longer. Today i quit a medical research trail because this app is useless ### 1/5 — Buggy, doesn’t function *2022-01-28, version 8.0* l don’t know what they’ve done but lately this app does not work. At *all.* It is completely non-responsive. I won’t bore you with the deets of my futile phone call to their “support” number; suffice it to say that’s a half hour of my life I’ll never get back. I’m inclined to bail out of this study early because I didn’t bargain for this particular aggravation. ### 1/5 — Worst app ever *2022-01-26, version 8.0* The fact that worldwide clinical trials are relying on this horrible, useless, never functioning app to collect data from participants is frightening. The notifications have never been consistent - the e diary is a joke. And the troubleshooting tips - a 10yo could’ve created a better app. Wonder how much this developer is getting paid. ### 1/5 — Won’t work until reinstalled, every time you need to use it! *2022-01-20, version 8.0* Can’t reach and input symptoms on diary page until you delete and reinstall. Every time! ## Most critical reviews (10 lowest-rated) ### 1/5 — No longer works *2025-02-13, version 18.0* As other user had said no longer working since last update February 2025 ### 1/5 — So far totally underwhelmed *2023-01-18, version 11.2* I’m told this is the app I am to use to participate in a study. So far I’ve put my username and password in about ten times and then from there the screen goes completely blank. The link in the email also does the same thing. Useless. ### 1/5 — Entry acknowledgement *2022-12-16* Study does not acknowledge user having completed the cold symptom entry. Even if user logs out, then logs back in, study still demands the user answers cold symptom! After the date changes study seems undecided. To clear issue, log out and log back in. Poorly programmed. ### 1/5 — The app lets the whole study down *2022-12-07, version 10.1* The study I take part in is so precise and detailed I have no idea who decided to go with this app. The notification symbol won’t clear after completion of the survey. I am unable to complete my health assessments during a bout of cold, the very time the study is centred on! Tried logging out - No! Delete and reinstall - No! Awful! ### 1/5 — What’s up with that? *2022-10-03* I’ve been prompted to change password but I access app by facial recognition. Do I need to change my facial features? Thanks ### 1/5 — Still dreadful if *2022-07-14, version 10.0* Nearly 2 years since I started using this and it’s still as dreadful as ever. One can only read the “update” notes and chuckle were it not for the sheer time and frustration that this poor excuse for an app inflicts on its unlucky users. Complicated user interface that often trips up. “We’re working on it” error message all the time. Notification icons on my home screen that don’t reflect the number in the app together with the fact that neither can be easily cleared. Absolutely crap and has put me off anything produced by this developer and on any future participation in clinical trials requiring any kind of mobile-based data collection. ### 1/5 — One of the worst apps made. Crashes when try to open *2022-07-07* Deleting the app.. worthless app ### 1/5 — Worst App *2022-07-02* This is, without a doubt, the worst app I've ever encountered. I'm enrolled in a trial and all it's used for is a one question (yes/no) check-in. When you respond, you get no acknowledgement, and if there's a problem, you can't tell. You can't edit or clear anything, so missed or non-registered check-ins sit in your to do list indefinitely. They told me I can do a workaround by distinguishing between what's "Available" and what's "Required" on the assignment page. I'll tell you what's a better workaround: a piece of paper with a phone number to call if you have a positive response to report. ### 1/5 — Confused with alerts *2022-06-16, version 9.2.1* Got multiple alerts to complete symptom check when I thought it had reduced to every fortnight on Wednesday. Go in the app and one isn’t even due. Completed it anyway, but now I’m so confused. I’m leaving this trial. ### 1/5 — One of the worst apps ever *2022-05-26* The current rating of 4.5 is fraudulent; simple arithmetic confirms this. ## Most praised reviews (10 highest-rated) ### 5/5 — Updates on this app didn’t impact its functionality *2022-07-11* There are always a few issues associated with App updates. The updates on this app did not impact its functionality. ### 5/5 — Thanks *2022-05-15* Everyone is so helpful when I call ### 5/5 — My experience *2022-04-16, version 9.1* Maybe I’m an outlier but I’ve never had any difficulty logging in or using the diary. Maybe I’m the exception but just thought I’d share. ### 5/5 — To Zarqua *2021-11-29, version 7.1* The app is great. No issues. I don’t know why someone would be so rude about an app lol ### 5/5 — Bunch idiots crying over a app *2021-08-04, version 6.2* You just need to add yes or no ! ### 5/5 — Works fine for me *2021-06-28, version 6.1* I have no idea what everyone is upset about. The app works fine for me and I have never had an issue with it. ### 5/5 — The best experience ever *2020-11-26, version 5.5.01* I use this app more then 3 months and I like that when I find any issues - support team reacts on my feedback and I see all fixes and updates in new version soon - it is cool that IQVIA developers think about users and try to make the App better ### 4/5 — I’m good *2021-06-28, version 6.1* Thanks for a way to keep me posted and give you only the info you need. That’s work’s for me. ### 3/5 — Where’s the new version? *2024-04-27* My app is telling me a new version 15.0 is available & to update, but it’s not really available yet because what’s here in the app store is 14.1? Otherwise, the app works well for what it does & what I need it for. ### 3/5 — Never clear *2022-05-09, version 9.1* Even after entering your info it won’t clear the notification alert. I have to open it again the next day to clear --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
