Lectrosonics® SM transmitters must be configured to accept remote control tones. Hold down arrow while turning on the transmitter. Then select "rc on". The original SM requires firmware version 1.5 (released 12/05) to respond to the remote. The firmware version number appears upon turning on the unit. Any tones properly received but not supported will be met with "---------" response on the transmitter screen.

### 5/5 — Great! but sound bug?

*2026-04-14*

I’ve used this app for years and is a necessity but have noticed that sometimes when locking and unlocking my phone will trigger the dweedle.

### 1/5 — Terrible app

*2024-07-13*

Absolutely shocking app doesn’t work don’t download don’t waste your money

### 4/5 — Nice update, but?

*2021-04-26*

The frequency change section for SMWB is not shifting blocks correctly. Whatever block you choose it sends the Hex channel
and always sets the transmitter to block 470. Help!

**Developer response:** Wideband blocks are labelled differently from narrowband blocks. Look for the blocks that start with a letter: eg A1-470, B1-23, etc

### 3/5 — Why isn’t Watch app included?

*2020-08-21*

This app makes it so easy to adjust settings to many transmitters at once, or if the transmitter is buried in clothing/costume.

But why is the Apple Watch app an additional $17???

**Developer response:** Development and maintenance for new platforms requires work and equipment. The audience for Apple Watch is much smaller as well. The Apple Watch app is priced to suit the amount of work required and the number of users who will buy it.

### 5/5 — Great solution but has a bug

*2019-08-10*

If you touch the refresh symbol in the top right corner the app crashes and will not reopen.  You have to delete and the reinstall.  I have the new iPhone X.

### 5/5 — I wish

*2018-09-05*

That this ap could change volume by steps : IE plus or minus a value instead of a fixed volume setting as is offered now. I use a lot of lectro radio mic’s and we lose track of the volume setting on a transmitter. It would be super helpful to add or subtract a value !
Love this ap! It rocks! 
And it can by the way change power settings of the transmitter !

### 5/5 — Must have

*2018-03-04*

I’m a boom operator since 1993. This app is indispensable. Best $20 I’ve ever spent.

### 2/5 — Screen invert broken

*2017-08-26*

Use to be able to flip the screen so that the speaker on the bottom of the phone can be oriented away from you and towards talent. It's a minor gripe but the feature that use to work is broken now.

### 5/5 — Crashes on iOS version 10.3.1 now

*2017-06-25*

Crashes on iOS version 10.3.2 now. 
which great on set yesterday, but today it won't even open and crashes totally screwing me on set.

### 5/5 — Incremental Mode does not work on my SMV's

*2017-04-02*

My mistake, SMV's require V5.5...... mine were V5.3
