Spindump data is very useful when debugging sluggishness in Texpad. The spindump tool samples Texpad as you use it, recording where in the code the time is spent.
When writing to us about performance issues, please ensure you state the device you're using, the operating system you're running (version of macOS, Windows or iOS) and any other information about the environment Texpad runs in.
It is currently not possible to collect the spindump data on iOS from a user device.
If you're having performance or memory consumptions problems with Texpad on iOS, please provide detailed description of the scenarios that lead to performance issues. In addition, if the problem arises with a certain class of documents, please share a small example with us that demonstrates the problem and may help us reproduce the issue.
