UIDesignStudio is a paired tool with the iOS library UIDesignManager. Enter your bundle identifier and passkey to start modifying and saving colours, fonts, sizes, constraints of configured UI components within your app. All changes will take affect immediately and will reflect on users devices the next time they open your app.
This gives you the freedom and flexibility to control UI parameters on the fly.
Please note: In order to save new settings and parameters within UIDesignStudio you will need to subscribe to the auto-renewing in-app purchase called "Pro Features". This is a monthly subscription and can be cancelled at any time.
1 month free trial.
