You can also save your games and you can also send to yourself via email your games in PNG format. You can also load a previously saved game.
Shedder is available on both iOS and Android.
There are some that do it easier then others but there is a simple way. Pretty much any chess program can use use this method.You just have to save the FEN at the branch. Play it out and go back to original position or re-paste the FEN you saved.
Thanks for the replies. I might look into those, but what I was really hoping for was a simple app that could do what I described with no analysis or play against the computer. Just something to manually make the moves according to an annotated game with the capability to save a board position in order to play out the alternate lines that are described, and revert to the saved position and continue with the real game until other alternate lines come up. I think it would be a valuable way to study. If there isn't an app that specifically does that, I'll check into what Rubicon and KineticPawn suggest.

When you say "app", you mean you want this on your phone or tablet?
The Shredder app will do this.
If you're happy to use a PC you could get Fritz (you can pick up older versions very cheaply). You could then record the game, all of the variations you look at and also your own thoughts if you want to.
Alternatively you can use the low-tech solution of using 2 chess sets, but I suspect you've already thought of that!

I wrote it. It allows you to bookmark games.
Lucas chess is great for that. For any board position it will show you a list of all the top moves and you can show the best lines for each of those moves. You can vary from the computers line at any time and see the evaluation of an alternate move. Then you can close out the best moves screen for that particular position and go back to the game position. The actual game analysis screen has the list of moves to the side, color coded by strength of move. you can click through to any point in the game, and click on any move to open up the best moves option Window. That Window shows you the line for any of the top moves and lets you look at the variations to its line.
Did you find anything that worked for you?
I'm also interested in a tool for this. I think I'm aligned with the OP in wanting a tool that helps me explore a tree of potential moves _without_ an evaluation or recommendation. I'd like to make my own evaluations, add those as annotations to the tree and use it as a note-taking tool to help me determine the best moves. So my ideal tool has a board that I can move forward/backward through move sequences, and also a convenient tree visualisation that shows my evaluations.
I think you could do all of that with many tools. But I've got "SCID vs PC" which many people regard as the best free chess GUI available. You can use it with an engine switched on of off so you can make your own analysis before you see what the engine thinks.
There are YouTube videos showing how to use it, which will also give you an idea of what you can do - for example:

This video is quite slow and slightly annoying but covers the important stuff in an understandable way.
Hello,
I have annotated games that I study, which explain alternate lines and why they are bad. Some of them go on for 6 moves or more. It's hard to play them out in my head when I'm using a real board to study the game(s) and if I attempt to move the pieces so I can see them, I may lose track of where the real game board position was. Therefore, although I like using a real board, it would be valuable if there was an electronic app that allowed me to save a current board position, play alternate lines and then go back to the current position to continue studying the annotated game. With all the electronic chess game software that exists, I would think that one of them had the capability to do this. Does anyone know?
Thanks & Regards,
Lance
