OrigamiCreaseMap

The truly challenging part of origami often lies not in the hands, but on the paper – if one step collapses and ruins the model, it's put aside; after two weeks, when it's picked up again, one has forgotten exactly where they left off, what kind of paper was used, and why they didn't continue at that time. The Origami Crease Map is specifically designed for this purpose. It doesn't serve as a riddle or a showcase of paper-cutting materials; it simply quietly reminds you of each model: the author or source of the tutorial, the level of difficulty, the size and weight of the paper, the key points of the folding sequence, the most prone step to collapse, and what the final product should look like. Each folding sequence can be marked as a "difficult step", so during practice, only the current step is unfolded, and all previous steps are folded up, and even large models won't be spread out on one screen to intimidate oneself. The most practical aspect is "continuation from the break". Unfinished works will save the step they were at, and the next time the crease map is opened, it will directly stop at that position, without having to re-read the tutorial from the beginning. For the same model on a different piece of paper, the success rate will be separately recorded: if a certain type of paper always collapses and fails, it will be noted on this piece of paper alone, rather than suspecting that the folding sequence is wrong. "Paper problems" such as moisture or fraying, and "folding sequence problems" are counted separately over time, and it can be seen whether it's the paper that's the issue, or whether you haven't done the step correctly all along. When demonstrating to others, you can also save a simplified version of the folding sequence: the complete version is used by yourself, and the simplified version is used on the spot. After the demonstration, jot down "which step is most frequently asked about", and these questions will, in turn, remind you that only you can understand the annotations, while others actually can't keep up. All the content is stored locally on the phone, and can be used without an internet connection. No camera permission is required, no photos are taken, no upload is involved, and you won't be asked to register an account. It's suitable for saving those complex models in the tutorial folder and truly turning them into a record that you can stop and continue folding.
