Device requirements The RS-MS1I operating requirements are as follows: iOS16 or later Usable transceivers (As of May 2026) - ID-4100A/E + Bluetooth unit (UT-137) - ID-52A or ID-52E *1 - ID-52A PLUS or ID-52E PLUS *2 - ID-5200A or ID-5200E *3 - IC-705 *4 *1 Supported in RS-MS1I Ver.1.1.0 or later. *2 Supported in RS-MS1I Ver.1.3.0 or later. *3 Supported in RS-MS1I Ver.1.4.0 or later. *4 Supported in RS-MS1I Ver.1.2.0 or later. Preparation To use the RS-MS1I with a supported transceiver, you need an optional Bluetooth unit. See your transceiver’s instruction manual for details. Transceiver’s settings Set the following functions as shown below to use the RS-MS1I. [Function] > [CI-V] > [CI-V Transceive]: ON [Bluetooth Set] > [Data Device Set] > [Serial Port Function]: CI-V (Echo back OFF) Note: - The RS-MS1I may not work with all iPhones or iPads, even if they are one of the tested devices. This is because an application program on your device may conflict with the RS-MS1I. - The RS-MS1I may not be used, depending on the OS version, installed application, and so on. - Bluetooth LE is used for the connection with the transceiver, so there may be a time delay between the transceiver’s operation and the display on the iPhone or iPad. - When sending or receiving pictures using “FAST mode,” the headset audio will be temporarily interrupted because of the transceiver’s Bluetooth unit limitations. - You may need to connect to the Internet through a Wireless LAN, an LTE network or a 5G network for some functions. - The RS-MS1I supports only portrait orientation with the iPhone. It does not support Auto Rotate. However, landscape orientation and Auto Rotate are supported with the iPad.

Verdict
The clearest difference is review sentiment: Morse Code at 70% against RS's 16%. Morse Code also leads on update cadence (every 6 weeks vs every 8 months). RS's advantage is rating (1.9 vs 1.0) and in-app purchases (none vs 1). On price and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Morse Code sells 1 one-off in-app purchase. RS asks for nothing beyond the download.
RS holds the better App Store score, 1.9 against 1.0. That said, the two scores are not equally well evidenced: RS has 75 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 16% of RS's written reviews are positive against 70% of Morse Code's, so the app with the better star average is not the one people write more warmly about.
RS ships an update every 8 months, Morse Code every 6 weeks. The most recent releases landed on October 1, 2026 and September 21, 2026 respectively.
