hallon.se Saldo is a third-party application developed by Filip Lindqvist, which allows you to check your balance directly from your mobile device. It is available on the Android platform and is free of charge. The app reads directly from "my pages" on the operator's website and, therefore, there is no intermediate server. It allows you to see your balance for calls, SMS and MMS, and data traffic.

The app is easy to use, and you can switch between numbers by swiping left or right. It also has a widget that updates every 60 minutes. However, it is worth noting that devices from the brand "Lenovo" seem to have problems with the app, and in case of login issues, the developer may have difficulty helping users.

It is important to mention that this is a hobby project, and the developer encourages users to provide feedback and suggestions. It is a beta version, and users can apply to join the beta testing group to help improve the app.

Overall, hallon.se Saldo is a useful tool for hallon.se users to keep track of their balance on the go. However, as a third-party app, it may stop working if the operator updates their website.
