Your bill.
Ready to review.

See the amount due, open the invoice, and expand its bank-transfer details. Copy an individual field or review the QR in your banking app.

Try Bills with sample invoices. The demo QR contains no payment instructions.

Each SIM. Its own balance.

Switch between SIMs and bundles. Each SIM keeps its own allowance and extra charges.

30 days of SIM usage.

Inspect daily usage across bundles. Current-cycle totals stay separate from the clearly labeled estimate. Missing days remain distinct from confirmed zero usage.

Account bills.

See the latest invoice or credit note. Grouped totals stay labeled as account-level amounts, the unpaid amount remains separate, and Open PDF is always an explicit action.

Customer-wide Viking Points.

See available, pending, and blocked points with recent transactions. The customer balance stays the same when you switch SIMs.

Settings that persist.

Choose used or remaining data, set a refresh interval, and enable launch at login. VikingBar also refreshes after wake. Settings shows the connection status and username, with an explicit Change account action.

Bank transfer QR.

For an eligible unpaid invoice, Bills refreshes the invoice details and generates a QR locally, with copyable recipient, IBAN, BIC, and reference fields. You review and authorize the transfer in your banking app. VikingBar does not execute the payment.

Setup

Request API access first

API access is not included automatically with your Mobile Vikings account. Email api@mobilevikings.be with your name, the brand (Mobile Vikings), the application (VikingBar), and its purpose (viewing your own balance). Ask support to approve VikingBar as a public client without a client secret. Wait for that confirmation and your public client ID before connecting. No client secret is required for the approved public-client setup.

Questions

Do I need API access?

Yes. Email api@mobilevikings.be to request access before connecting. Include your name, Mobile Vikings as the brand, VikingBar as the application, and that you want to view your own balance. Wait for their approval and public client ID.

Do I need 1Password?

No. Sign in directly with your approved public client ID, username, and password. The configured 1Password helper is optional, and no client secret is required.

Can anyone download VikingBar?

Yes. The free unsigned preview is available from GitHub without an account for Apple Silicon Macs running macOS 14 or later. It is not Developer ID signed or notarized. If macOS blocks the first launch, open System Settings, choose Privacy & Security, then click Open Anyway. Updates may require approval again.

Where is the session stored?

The refresh session is stored in macOS Keychain.

What happens if a refresh fails?

The last successful balance stays visible and is marked as out of date.

Can I switch between SIMs?

Yes. Choose a SIM and then a bundle in the menu. Each SIM keeps its own allowance and extra charges.

What does the 30-day chart show?

It shows daily SIM data use across bundles. Current-cycle totals stay separate from the clearly labeled estimate. A missing day stays different from a confirmed zero.

What account information does VikingBar show?

Bills show grouped account totals, a separate unpaid amount, and an explicit PDF action. Viking Points are customer-wide and keep available, pending, and blocked balances separate.

Can VikingBar pay an invoice?

No. For an eligible unpaid invoice, Bills refreshes the invoice details and generates a bank-transfer QR locally using a bundled helper. No Go installation is needed. You can copy the recipient, IBAN, BIC, and reference individually. You review and authorize the transfer in your banking app. VikingBar does not execute the payment.

Which settings are saved?

VikingBar saves the used or remaining display choice and refresh interval. It refreshes after your Mac wakes and can launch at login when enabled in Settings.

Is VikingBar an official Mobile Vikings app?

No. VikingBar is an independent project for Mobile Vikings users.
