座標實驗室(CoordinateLab)是一款專為 iPhone 開發與測試情境打造的定位模擬工具。從 Apple 地圖搜尋地點、選擇單一座標,到規劃兩點間的駕車路線,都能在清楚、集中的介面中完成。 主要功能 ・地點搜尋與選點透過 Apple 地圖搜尋地點與地址、查看座標,或直接點選地圖上的位置。 ・單點定位模擬選定座標後啟動模擬,適合測試 App 在特定地點下的顯示、內容與流程。 ・路線模擬輸入起點與終點,取得 Apple 地圖提供的駕車路線,並沿路線進行開發定位測試。 ・速度控制可在 1–100 km/h 間調整移動速度,並選擇平順的速度變化,模擬更自然的移動過程。 ・暫停、繼續與停止模擬途中可隨時暫停,之後從目前位置繼續;停止時則清除模擬位置。 ・連線與配對狀態開始前即可確認本機隧道連線與裝置專屬配對檔是否準備完成,減少設定上的猜測。 ・冷卻時間提示依位移距離與 Apple 地圖預估時間提供參考倒數。此提示僅供參考,不代表任何第三方服務的官方規則或保證。 ・抵達通知完成兩點路線時,可選擇接收裝置本機通知。 隱私與資料 座標實驗室不要求建立帳號,也不會將你選擇的座標、路線或配對檔上傳至座標實驗室的自有伺服器。地點與路線請求由 Apple 地圖處理;App 內含 Google Mobile Ads 橫幅廣告,相關資料處理依你的地區、同意選擇與服務提供者政策而定。 使用前請注意 核心定位模擬功能需要: ・iPhone 開啟開發者模式・由受信任的 Mac 為該 iPhone 建立的專屬配對檔・相容的外部本機隧道工具與桌面載入工具 上述外部工具不包含在本 App 內。配對檔含有敏感連線憑證,請僅使用自己或經授權裝置的資料,切勿公開、分享或使用他人的配對檔。 座標實驗室僅供自有或經授權裝置的軟體開發、除錯與定位情境測試。請遵守適用法律及第三方服務條款。

Turn coordinates into your route. DotTrail is a route-file editor by LocationLab for iPhone and iPad. No app account is required. • Import and export GPX, KML, GeoJSON and CSV. • Recognize decimal, DDM and DMS coordinates in mixed text, then preview and create a straight-line route. • Connect points in order; select, drag, rename, reorder and delete them on the map or in the list. • Draw a polygon to preview and remove points inside it. • Generate a zigzag route inside a selected map area with adjustable spacing and direction. • Route Tools: add loops around selected points, use fixed or ranged offsets, and build circular detours. • Smart Organize: shorten a trip, optionally keep the end, return to the start, merge nearby points, or renumber names with a prefix. • Preview the original and adjusted routes with point counts and distance comparisons before applying. • Undo and redo, restore three recent saved versions, and recover deleted routes. • Save and reopen projects, export repeatedly, and back up the original import and history. • Sync with iCloud between devices using the same Apple Account. English and Traditional Chinese follow your system language. Free download with a bottom banner ad; no subscriptions or in-app purchases. Routes use straight lines and do not provide road navigation. Smart sorting uses straight-line distances, does not consider roads or obstacles, and does not guarantee a mathematically shortest route. Smart sorting supports up to 2,000 points; imports support up to 25 MB and 20,000 points. Multiple routes are combined in file order. GPX waypoints take priority over route data. Conversion retains supported fields; other original content remains available in a full project backup.

Verdict
CoordinateLab and DotTrail are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
