 "description": "初中计算错题特训是一款面向初中生的纯计算题变式训练工具。把错题算式变成可反复练习的同类题，帮助巩固计算能力。\n\n主要功能\n1. 拍照录入算式\n对准单行印刷算式拍照，或从相册选图。识别在本机完成，断网也可用。手写效果不佳时，可改用手动输入。\n\n2. 手动输入与校正\n提供数学键盘，支持逐字编辑、根号与幂次等写法。确认模板后再生成变式。\n\n3. 本地变式生成\n勾选需要随机替换的数字，设置题量（10至50）与约束条件。同一批次避免重复；可选开启避免重复历史题目。\n\n4. 练习与错题本\n作答后交卷查看正误。错题进入错题本，可基于历史模板再次生成练习。\n\n5. 全离线与隐私友好\n图片、算式与练习数据仅保存在本机，不上传服务器，不调用云端 AI，无需登录。可在设置中清除全部练习数据。\n\n支持题型\n四则运算、小数、分数（行内除法）、绝对值、平方根立方根与任意次方根、幂次、一元一次与一元二次方程、简单整式。\n\n暂不支持\n应用题、几何、三角函数、不等式与方程组、导数积分、多行堆叠分式。OCR 仅适合单行印刷体。\n\n使用提示\n请将算式完整放入取景框后再拍；识别有误可在校正页修改。若提示无法凑足全新题目，可临时关闭历史去重或减少题量。\n\n说明\n本应用定位为计算专项练习工具，不宣传提分、中考提分或保分等效果，请理性使用。\n\n联系方式\n应用反馈：请在 App Store 中留下评价和反馈",
