This app offers credit check for Vimla mobile network. You can use widgets on your home screen to keep track of your credit.

Regarding security and integrity of your login credentials, the app uses AES-128bit encryption against your credentials and saves them locally within its private storage folder (i.e. not accessible to anyone other than app itself). No data is saved or transmitted to any remote location. It's your data, your property, hence saved locally on your device only.
