Guesstimate vs Visual Finder｜Object Detector

Ever wonder "what's the answer if this number could be anywhere from 2 to 4?" Guesstimate is a calculator built for uncertainty. Use the ~ operator to define ranges in your formulas. For example, (2~4) * (1~3) means "a number between 2 and 4, multiplied by a number between 1 and 3." Guesstimate runs hundreds of thousands of Monte Carlo simulations to show you the full distribution of possible results. FEATURES - Uncertainty ranges: Use ~ to express "somewhere between" in any formula - Monte Carlo simulation: Up to 10 million iterations for accurate results - Interactive histogram: Tap bars to see exact percentages and sample counts - Box plot visualization: See min, Q1, median, Q3, and max at a glance - Full statistics: Mean, median, standard deviation, confidence intervals, and percentiles (P1 through P99) - Calculation history: Review and reload past formulas - Configurable settings: Adjust iteration count, histogram bins, confidence level, and distribution type (uniform or normal) - Built-in calculator keypad: No keyboard needed — dedicated buttons for digits, operators, parentheses, and the ~ range operator - Works on iPhone and iPad EXAMPLES - How much will dinner cost? (12~18) + (8~14) + (3~7) - Estimating project hours? (2~4) * (5~8) - Unit conversion with uncertainty? (2.79~3.09) * ((1300~1400) / (27~33)) No account required. No data collected. Just math.

Visual Finder detects people and objects in your iPhone or iPad camera feed in real time, letting you review, track, and record results as they happen. It supports 80 COCO-based categories, including people, vehicles, animals, and everyday items. Switch between Box, which marks objects with bounding boxes, and Mask, which highlights each object’s shape. Track detected objects, revisit them as cropped images, review each session through statistics and charts, and export results as CSV. Detection runs with Core ML directly on your device. —————————— ■ Real-time object detection Detect objects live through your camera. Choose only the categories you need or select all available categories. Each result shows its location, category, and confidence. The screen also displays the current detection count and inference FPS. —————————— ■ Box and Mask display modes Box surrounds each object with a bounding box for a clear view of its location and size. Mask uses instance segmentation to show the region along the object’s shape, revealing contours and occupied areas that a rectangle alone cannot capture. Use both modes to compare the same scene from different perspectives. —————————— ■ Object tracking Follow moving objects across camera frames. Each tracked object receives an ID, making it easy to distinguish multiple objects in the same category. —————————— ■ Cropped detection images Recent detections appear as object crops at the bottom of the screen. Tap a crop for a larger view and save selected images to your photo library. In Mask mode, crops follow the segmented shape. They can be saved as PNG files with everything outside the object made transparent. You can also adjust the history limit and haptic feedback for new crops. —————————— ■ Session summaries Results from start to stop are grouped into one session. Logs include: • Detection duration • Processed frames and total detections • Detected categories and counts by category • Detected frames and appearance rate • Average confidence and detection area • Maximum detections per frame • Average FPS Charts show changes over time and each category’s share. Review not only what appeared, but how frequently it was detected. —————————— ■ CSV export Export session logs in two formats: Summary, with overall and category statistics, and Data, with results for each frame. Share files through the iOS or iPadOS share sheet for use with spreadsheets and analysis tools. —————————— ■ Adjustable detection settings Fine-tune the maximum detection rate, confidence threshold, IoU threshold, minimum detection size, and Object Tracking. Choose 1, 5, 10, 20 FPS, or Max. Actual inference speed depends on the device, model, scene, and device conditions. —————————— ■ Camera selection Use available Wide, Ultra Wide, Telephoto, and Front cameras. Compatible external cameras exposed through AVCapture can also be selected. Camera availability and behavior vary by device, OS, and connected camera. —————————— ■ On-device processing Visual Finder uses Core ML. Camera frames are processed on your device and do not need to be sent to an external AI server for object detection. —————————— ■ Ideal for Explore AI, object detection, instance segmentation, and tracking with a live camera. Compare Box and Mask results, save object crops, analyze sessions or CSV data, and use the app for research, development, learning, demos, or external-camera tests. Some detection categories, Object Tracking, and ad removal require an in-app purchase. Results vary with device performance, lighting, object size and orientation, motion, occlusion, and other conditions. This app is not intended for medical, safety management, identity verification, or other uses where false or missed detections could have serious consequences.
