Turn a place into a new perspective. MapToNap brings architectural site analysis to your iPhone. Find a place, select a study area and create clear diagrams from real OpenStreetMap data. ⢠Explore 26 analysis types covering streets, urban fabric, green space, water, orientation, access and urban activity. ⢠Choose from 10 color palettes and adjust diagram framing, color and line weight. ⢠Save completed projects on your device and reopen them without generating them again. ⢠Work in light or dark appearance, with English and Simplified Chinese interfaces. ⢠Export PNG images. MapToNap Pro also includes SVG and PDF, watermark-free output and higher-resolution PNG. Four analysis types are free. Pro is available as a monthly or annual auto-renewable subscription. Payment is charged to your Apple Account. Subscriptions renew unless cancelled at least 24 hours before the current period ends. Manage or cancel in your Apple subscription settings. Availability of map detail depends on OpenStreetMap coverage and network access. Analysis diagrams are design references, not survey-grade measurements or measured environmental readings.

PixDim
Read full descriptionHide full description
PixDim is a focused photo utility for the times when a picture must fit an exact pixel size or file limit. Choose Resize or Compress, pick a photo, and set the output you need: ⢠Exact width and height, with an optional locked aspect ratio ⢠Fit, Fill or Stretch canvas, with a draggable crop position ⢠A target file size in KB or MB, using a real encoding search ⢠JPEG, PNG or HEIC output where supported ⢠Solid or transparent backgrounds ⢠Manual or automatic quality Before exporting, compare the original and result, inspect the actual dimensions, format and file size, and zoom in to check details. PixDim verifies the encoded file instead of estimating the result. If a requested limit cannot be met, it tells you instead of silently changing your dimensions. Your image is processed on your device, and the output is written without the original EXIF or GPS metadata. PixDim does not upload your photos. Limited product-interaction and purchase analytics help improve the app; see the privacy policy for details. Processing and preview are free. Export requires a purchase: unlock the current processed result, or buy lifetime access for unlimited single-image exports. No subscription. Lifetime access can be restored with your Apple Account. PixDim handles one image at a time. It is built for quick, precise exports rather than batch processing. Requires iOS 17 or later.

Verdict
The clearest difference is update cadence: MapToNap at daily against PixDim's every 3 days. MapToNap also leads on iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
