What Nanda does
The whole day at a glance
96 quarter-hours as a bar chart: cheap, average, expensive. Drag across the chart to read any moment exactly.
Tomorrow, the moment it is set
The day-ahead auction publishes in the early afternoon. Nanda fetches it in the background and shows it as soon as it is there.
The cheapest window
Nanda finds the cheapest run of the day, with start time, length and average price.
Exchange price or the real end price
On request Nanda adds grid fees, electricity tax, surcharges, the concession fee and VAT. Every item can be edited on its own.
Notifications
When the price drops below your threshold, when the cheapest window of the day is about to start, or when the price goes negative.
Home screen widget
Current price, the shape of the day and the next cheap window – right on the home screen.
What it looks like
Your data stays with you
No account, no registration, no ads, no tracking. Nanda collects no data about you.
Every setting – tariff figures, price boundaries, notification rules – stays on the device. Notifications are scheduled and delivered locally; no server is involved. To show prices, Nanda calls the public energy-charts.info API – that request carries the selected bidding zone and a date range, nothing else.
