5D

Download

5D Trust for two runs on iPhone and on Android, and the two of you can each use whichever you have.

iPhone

On the iPhone, 5D Trust for two is shared through TestFlight, Apple's app for trying an app before it reaches the App Store.

Ask for an invitation at springvibe77@gmail.com, install TestFlight from the App Store, and open the invitation on your iPhone.

5D for Android

Install 5D

Version 0.2.0 · build 3068 · 168 MB · 2026-10-18

What changed

The chat buttons no longer stop working after a cancelled call.

Installing

  1. Open this page on your Android phone and tap Install 5D. The download runs in your notifications; tap it when it finishes.
  2. Android will ask whether this browser may install apps. Allow it — once — and come back to the download.
  3. Google Play Protect may offer to scan an app from a developer it does not know yet. Let it, then tap Install.

After installing

  1. Add 5D to your home screen.
  2. Open the app's settings (long-press the icon, then App info — or Settings → Apps → 5D) and set:
    • Camera — Allow only while using the app
    • Location — Allow all the time
    • Microphone — Allow only while using the app
    • Notifications — Allow notifications, then choose sound or silent and the style you like
    • Pause app activity if unused — turn this OFF
  3. Install unknown apps — Allow from this source: ON

Staying current

  1. Once installed, 5D checks for a newer build once a day and installs it for you — nothing to switch on.
  2. The first update asks for the same one-time permission, this time for 5D itself. After that, updates are quiet.
