I couldnt draw for consecutive 5 seconds without the pen cutting out. Cant recommend *Deleting the Account is also laggy but the link to kitten pictures at the end deserves a second star ### 3/5 — Nice app but not easy to use on iPad *2024-03-25, version 2.0.5* The app keeps adjusting the Zoom resolution automatically which makes drawing really frustrating. I have to constantly re-adjust the zoom ratio. It would be really useful if there as an option to lock-down the zoom function on the Apple IOS app. ### 1/5 — Can not sign into app with Google *2023-05-16, version 2.0.5* Signing in with Google works on the website fine, but does not work on the app. Very frustrating ### 5/5 — I wrote a review *2021-08-20* I wrote a review once. WHERE IS IT???!!!!!😡😡😡😡🤬🤯 ### 1/5 — Deleted *2020-10-23, version 2.0.5* Das not work with out Account. Deleted the app at once. ### 3/5 — Needs work indeed *2020-09-05, version 2.0.5* I agree with the other reviews. I am using it in my remote class right now to go over problems and I am not impressed. The app works for casual sharing and brainstorming, but not really as a replacement for a board lecture or a presentation that involves ex tempore writing. The lack of palm rejection is distracting (I get lots of unwanted lines) as is the fact that one can too easily accidentally zoom in or out. Writing on the board feels a little like walking on a very slippery surface. You never know what might be happening next. Some form of palm rejection (what is with those straight lines that tend to show up when you rest your hand near the edge of the screen?) would be nice. An option to lock zooming would be appreciated. It also seems that zooming distorts handwriting that is not undone by zooming back. For lefties like me an option to move the menu to the top of the screen might be helpful. Not a big one, but I found that I really would like to be able not to just export a selection on a board, but also to copy that selection to another board (Think consolidating lecture notes onto one board). ### 1/5 — Signed up ...can’t create a board *2020-08-17, version 2.0.5* Signed up, hit create board...nothing happened. Tried various combinations to see if there was some failing validation. Nope. ### 1/5 — Can not login using Google *2020-08-05, version 2.0.5* Seems like a feature that could have been fixed in the last 4 years. Disappointing. ### 1/5 — Hard Pass *2020-07-30, version 2.0.5* Invites go to email. Then once invited you have to use that email to go to a webpage. Then the webpage MIGHT bring you to a white board? Hasn’t worked once correctly. Searching for a friend’s whiteboard shows zero results. Use a code instead? Nope. This app is ridiculous and requires too much activity outside the app. ## Frequently asked questions about Limnu ### What is Limnu?
