This utility app allows owners of GemTot bluetooth beacons to easily configure, test and demonstrate them. Distance demonstration: Demonstrates how an app is aware of a beacon's relative proximity when moving closer or further away from a beacon source and how the RSSI and power calibration of the beacon can be used to calculate a crude distance to the beacon source. Proximity demonstration: Demonstrates how the device's proximity to the beacon can trigger 3 different states (immediate, near and far), also shows how an app can respond to the event of no longer being able to see a beacon. Lock screen demonstration: Demonstrates how entering or exiting a beacon region can trigger a local notification and how a notification could be used to deliver content to Apple Wallet. This demo requires that background location monitoring and local notifications are enabled. Please note that continued use of GPS running in the background can dramatically decrease battery life. This app acts as a tool to demonstrate the capabilities of iBeacon. To save battery life, location permissions should be disabled when the app is not in use.

DimDash turns your iPad into a beautiful, always-on smart home dashboard with intelligent auto-dimming, device display controls, and full-screen kiosk mode for wall-mounted setups. Point DimDash at any Home Assistant, Grafana, Dashy, Homarr, Glance, Node-RED, or Flame dashboard and walk away. When you stop interacting with the screen, DimDash smoothly dims the display so it does not burn in or blast light across the room at night. Touch anywhere to wake it instantly. How it works DimDash loads your dashboard URL in a full-screen web view. An idle timer starts after your last interaction. When it expires, a smooth overlay fades in to dim the display. Touch the screen and the overlay fades out with your dashboard exactly where you left it. Device display controls DimDash can keep your device awake while the app is open so your wall panel does not lock. You can also enable DimDash Brightness to apply a chosen device brightness whenever the app is active. Dashboard customization Hide Home Assistant header or sidebar chrome with built-in kiosk URL controls. Use opt-in JavaScript Injection snippets to hide common nav bars, prefer dark mode, disable text selection, hide scrollbars, or add your own validated script that runs after the dashboard loads. Integration templates Getting started takes seconds. Choose from built-in templates for Home Assistant, Grafana, Dashy, Homarr, Glance, Node-RED, and Flame. DimDash auto-fills recommended settings.

Verdict
The clearest difference is in-app purchases: GemTot SDK at none against DimDash's 2. GemTot SDK also leads on iOS requirement (9.0 vs 16.0). DimDash's advantage is update cadence (every 3 days vs every 3 months). On price, ads and device support there is nothing between them.
