The Letus Helix app is designed to be a simple and intuitive way of changing settings on the Letus Double Helix, Helix Pro, Standard Helix, and Helix Jr. Many settings from the SimpleBGC GUI (PC/Mac-based configuration program) have been eliminated, because those settings are only needed to work with other gimbals or are rarely used. Additional tools to help the user have been created to assist the user in their use of the Helix. Connection with the Helix is done as follows: 1) Turn the Helix on 2) Go to the Home screen on your iPhone/iPad. 3) Find Settings -> Wi-Fi and select your Letus Helix. 4) Enter the wifi password found in the app help files (found by pressing the info button on the app's main menu). 5) Once it connects in iOS, you can go to the app and press the connect button.

ReceptionRating · Positive reviews · Number of ratings

Dragonframe Tether holds the better App Store score, 4.2 against 3.7. That said, the two scores are not equally well evidenced: Dragonframe Tether has 15 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 80% of Letus Helix's written reviews are positive against 43% of Dragonframe Tether's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Letus Helix ships an update every 4 months, Dragonframe Tether every 3 months. The most recent releases landed on June 11, 2026 and September 14, 2026 respectively.
