The Calpak-VBus®Touch app makes solar yield visible. In addition to a hydraulic scheme and a temperature progression chart, the solar heat gained will also be displayed. To visualise an individual system with VBus®Touch, a controller equipped with a VBus® interface and connected to the Internet by means of a Datalogger or Communication module is required. The basic version of the VBus®Touch app is available free of charge. Extended features will be available as modular add-ons which the user can individually combine.
SungrowEye

- Real-time data monitoring
- Direct register access
- Internet or offline operation
- Broad Sungrow system compatibility
- Specifically for SH10RT models

SungrowEye is a real-time monitor for Sungrow solar systems, retrieving all necessary data directly from the solar system’s register without requiring an internet connection. If the solar system’s register is made accessible over the home network for internet use, the data can also be retrieved in real-time over the internet directly from the register. SungrowEye was specifically developed for the SH10RT model. However, as the internal register of Sungrow solar systems, with so-called I18N values, should be compatible across different models, SungrowEye should work with all common Sungrow solar systems.

Verdict
The clearest difference is price: Calpak VBus®Touch at Free against SungrowEye's $7.99. Calpak VBus®Touch also leads on iOS requirement (9.0 vs 18.0). SungrowEye's advantage is update cadence (weekly vs fortnightly). On review sentiment, ads, in-app purchases and device support there is nothing between them.
