角度测量
Read full descriptionHide full description
角度测量把取景、水平仪和位置信息放在一部手机里。对准墙面、地面或设备,屏幕上的圆盘会跟着手机倾斜滚动,俯仰、翻滚、倾斜同时显示,读数精确到小数点后两位。 【相机测角】 打开相机即可测量。竖直握持时为 0°,镜头上仰为正,屏幕朝上贴平桌面时倾斜接近 90°。圆盘里的小球表示当前姿态,接近水平时会变色提示。需要时打开网格和中心十字线辅助对准,也可切换前后摄像头。 【保存与记录】 拍下当前画面,角度会一起留在图片上,并自动进入测量历史。可按条预览、删除,或把选中的图片导出到相册。记录只存在本机,不需要账号,也不会上传。 【位置与太阳角】 授予定位后,可查看经纬度、精度、海拔、气压,以及当前位置的太阳高度角、方位角和参考倾角。适合装修找平、施工看坡、核对设备安装角度,以及估算太阳能板朝向。 【使用说明】 测角需要相机权限,定位和太阳角需要位置权限。测量时尽量拿稳,避免在行驶或剧烈晃动时读数。室内或信号弱时,定位会变慢、精度会下降。没有气压计的机型会用估算气压,海拔仅供参考。 支持中文和英文。需要 iOS 15 或更高版本。

Verdict
The clearest difference is in-app purchases: 角度测量 at none against SolVisIQ's 3. SolVisIQ's advantage is update cadence (every 4 days vs every 9 months) and iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.
