Maply helps you bring any custom map into the real world. Use a photo, an image from your library, or a shared Maply file to place a park map, museum guide, zoo plan, fair layout, campus map, trail map, or event floor plan directly on top of Apple Maps. Once the image is aligned, your live GPS position appears on the custom map, so you can understand where you are without switching between a static picture and a map app. Whether you are exploring a large park, visiting a museum, attending a trade show, navigating a festival, or saving a private map for later, Maply gives you a clear way to organize and reuse the maps that matter to you. Key features: - Import a map from your photo library or camera - Overlay custom map images on Apple Maps - Align maps with move, scale, rotate, opacity, and perspective tools - Use real-time GPS on top of the aligned map - Save maps in your personal library - Add points of interest with titles, descriptions, and icons - Save a photo of the map legend - Import maps from QR codes - Share and back up complete maps with the .maply file format - Restore compatible maps through iCloud documents Maply PRO unlocks advanced tools for people who want to create and manage more maps: - Unlimited saved maps - Corner pin and perspective warp - Automatic alignment tools - Points of interest - .maply sharing - Full import and export Maply is designed to keep your data under your control. Your imported maps, alignment settings, legends, and points of interest are stored on your device using Apple standard storage. Maply does not include advertising trackers, third-party analytics, social tracking, or developer-managed user accounts. Location access is used only to show where you are on the overlaid map. Camera and photo library access are used only when you choose to import map images or scan QR codes. Create your own map library, align the places you care about, and explore with more context.

Kaltrix turns your drive into an informed one. It fuses cross-brand radar-detector telemetry with a fast, navigation-grade live map — so the road ahead is never a surprise. Most driving apps show you where you are. Kaltrix shows you what's coming: a real-time, crowd-sourced awareness layer built from drivers around you, laid over turn-by-turn navigation that actually knows which way you're facing. WHAT YOU GET • Live awareness map — a clean, tactical dark map that surfaces corroborated road alerts ahead of you, color-coded by type and confidence. • Navigation-grade routing — turn-by-turn directions with lane guidance, speed-limit display, and smart departures that don't open your trip with a needless U-turn. • Connect your detector — pair a compatible radar detector over Bluetooth to fold its signals into your map, or run in crowd-only mode with no hardware at all. • CarPlay built in — a purpose-built CarPlay experience: glanceable maneuvers, your speed and the posted limit, and awareness cues, all sized to your car's screen. • Trip history & replay — every drive is saved; look back at your route, speed, and a shareable trip summary. • Crowd-powered, privacy-first — you contribute anonymized, coarsened signals and get everyone else's in return. Your precise location is never shared or logged. BUILT FOR AWARENESS, NOT DISTRACTION Kaltrix is a driving-awareness tool in the spirit of the road-alert apps you already know. Everything is designed to be understood in a glance and to keep your eyes on the road. PRIVACY Sharing is anonymized and location data is coarsened on our servers before anyone sees it. We never log your coordinates. Read our full policy at kaltrix.app/privacy. Drive aware. Drive Kaltrix.

Verdict
The clearest difference is in-app purchases: Kaltrix at none against Maply's 1. Maply's advantage is update cadence (daily vs every 6 days). On price, ads, device support and iOS requirement there is nothing between them.
