Justice for iOS
 
    
  
  
   
    
  
  
  They’ll also tell you why your move is wrong (what the opponent will do to counter)
Until recently, I didn’t know this existed and puts app users at a disadvantage in puzzles too.
 
    
  
  
  Yeah. iOS doesn’t have access to it. It’s made Daily Games harder overall, because I am not able to form cohesive plans. 
Some may say that the “Notes” feature is good enough, but Notes can be misinterpreted, and I often forget to check or clear them. 
Not only that, conditional moves can also reduce waiting times. If there is a forced checkmate sequence (and their opponent wants to play until checkmate), conditional moves get it over with quickly, whereas not being able to use conditional moves will require the player to manually move every time, and their opponent to wait to be checkmated, adding unnecessary waiting and worsening the playing experience of both players, even if one of them isn’t using iOS. 
As a person who really only mainly plays Daily, life without conditional moves is extremely difficult, and conditionals are an overlooked but useful feature that can win or lose games. The lack of Conditional Moves personally makes me forget and have to rediscover my plans every move, and it puts every iOS user, at that inherent handicap. For example, one time, I set up a checkmating threat, which my opponent didn’t see, and so they blundered Mate in 1. Without Conditionals to help, I forgot about my threat, and ended up missing the checkmate that I had set up.
 
    
  
  
  And for those who play Live games over Dailies, iOS also lacks multiple Premoves. The faster the game, the more iOS users are handicapped, since queuing up moves (like a pawn promotion) is not only satisfying, but essential if your opponent moves fast. Premoving multiple moves in advance allows you to move quickly, while making sure your opponent needs to waste time making their moves. Without multiple Premoves, iOS users are forced to make their moves one premove at a time, which can be very frustrating if the opponent has access to multiple Premoves. This can lose iOS users precious tenths of a second every so often. And while that doesn’t sound like much, it adds up. This makes playing Bullet or even Blitz at a high level effectively impossible. Just like in Daily Games, queuing up multiple Premoves can quite literally mean the difference between winning or losing a game. (Plus, let’s be honest. Premoving a Pawn all the way up the board or ladder-checkmating like you’re Hikaru is super satisfying. We should be able to experience that, too.) 
All in all, that is really what I mean when I say that iOS is at a huge disadvantage. iOS is effectively handicapped in any games they play, Live or Daily, fast or slow. And the debuffs they get can quite literally lose them otherwise won games.
 
     
     
     
    
I found two more!
- Deletion of saved bot games
- Alternate daily game layouts (website has 2, Android has 3)
I have added them to the list.
