Sinks with the cloud. Like it **Developer response:** Hi! Thank you for your feedback! We really appreciate it! ### 2/5 — Can't import MPP directly *2022-04-28* I can't import a MPP file directly when sent to me in MPP format. I must have a converter outside of this app to make it work with this app. Plus, I can't import from iCloud.. ON AN APPLE DEVICE! Really? This is made for Apple iPad, but can't import from the Apple online storage? I'm out the $79 I paid to get the annual subscription before I figured out it wouldn't do what I needed. **Developer response:** Hi! Thank you for your feedback! We are really sorry you've encountered issues with our app! Please submit a ticket with more information about your issue at https://www.projectplan365.com/newticket/index and our Customer Support Team will help you as soon as possible. ### 2/5 — Saying more than viewer is optimistic *2021-06-30* As a project manager running 7-10 projects in a given quarter, I was excited after getting my iPad Pro and found this app to let me work alongside MPP, eProject (homegrown), and Mavenlink - particularly while sitting at home. And with the new Apple keyboard, even better. I have been disappointed after spending my $79. So far I’ve lost work because the save has proven unreliable to OneDrive (work’s primary). You think it saved your updates and on Monday you find you have to edit your project again in a “real” PM app. Extremely frustrating to actually use. Unlike MPP, I cannot use the keyboard to navigate the task view. I also cannot enter values in it as if it were excel-like (like MPP). You must tap on the cell; tap again to allow editing - in which case the screen jumps to 200% view and putting the cell 10% below the screen…and you cannot move the app up to see the whole cell. As soon as you edit the cell you cannot tab to the next, click on the next, tap anywhere else, it doesn’t matter - you are thrust back up to LINE ONE of your plan. My plans are all over 300 lines (the one I’m on right now has 642). This is totally unacceptable and massively frustrating. No, this is not an editor. This is a viewer that lets you see everything and you can pinch and zoom out - but not edit that way, and the ones I mentioned alone means (very sadly) this will be a rarely used application - and the most expensive mistake for iPad software in years. **Developer response:** Hi! Thank you for your feedback! We are sorry to hear that you encountered issues while using our application! We would be grateful if you could submit a ticket with more information about your issue at https://www.projectplan365.com/newticket ### 1/5 — Subscribe? No thanks *2020-09-09, version 20.18* You either pay once or not at all, this subscription yearly fee nonsense has to stop. Vote with your wallets people. ### 1/5 — Not as advertised *2020-01-20* I downloaded it and tried to open a project I already created only to be thrown a lengthy error. Tried another with the same result. Tried a blank *.mpp file and got the same result. I think I’ll just quit using it after trying it for 20 minutes. **Developer response:** Thank you for your review. I’m sorry to hear you had a bad experience, but I really appreciate you bringing this issue to our attention. We are looking into this issue and hope to resolve it promptly and accurately. In order to investigate your issue please submit an online ticket at https://www.projectplan365.com/newticket. ### 1/5 — Crashes *2019-08-02* Installed and linked it to our One Drive and the app crashes every time I try and browse folders to get to a project plan. No error messages of any type. Just blows itself up. Not a robust application. Too bad I can’t open a file and give it a spin. **Developer response:** Hi! Thank you for your feedback! We are sorry for this inconvenience. Please submit a ticket with more information about your issue at https://www.projectplan365.com/newticket ### 1/5 — Not free *2019-06-15* It's scamming you making you to think it's free to get and 'use' but you can basically do nothing unless you pay like $130/year. You get one month free trial but if you don't cancel it in right time... Unless you just need it for a day and have time to set up everything for that free trial, don't even bother downloading it. I just wasted my time. **Developer response:** Hi! We are really sorry for this confusion! We offer 30 days free trial version of the fully functional product. Please follow these steps in order to activate your 30 days free trial: 1. Open application 2. Go to menu Help > Register 3. Click on Start Advanced View-Only Subscription button 4. Wait for the confirmation message 5. Restart application 6. After that, you have 30 days available to cancel your subscription. For more information about how to cancel a subscription, please follow the steps described at https://support.apple.com/en-us/HT202039 ### 1/5 — Rubbish *2019-01-11, version 18.41* Opened on iphone x plus and all it provides is a list of tasks in a non sensical layout that cannot be viewed with any context so is totally useless. It might have some value on ipad but meaningless on a smaller device. At least its free and not paid for or I would be proper miffed. ### 1/5 — Не работает, все платное *2018-10-19* Кириллица в заметках не отображается Нет поддержки yandex disk **Developer response:** Hi! Please submit a ticket with more information about your issue at https://www.projectplan365.com/newticket/index ### 3/5 — Great When working *2018-02-17* Bombing right now, love it when it was working. Hopefully just an update related to iOS. **Developer response:** Hi! Thank you for your feedback! Please update your application to our latest version! If you encounter some issues, please open a ticket at https://www.projectplan365.com/newticket/index ## Frequently asked questions about iProject Viewer ### What does iProject Viewer do? iProject Viewer allows you to open, view, and edit Microsoft Project plans (MPP files) directly on your iOS device.
