Changelog

v6.5 July 15, 2026

Group your appliance buttons by type — shown as rows or columns — so the programmes for the same machine stay together. Vehicles can still have their own section above or below.

v6.4 July 14, 2026

Share your setup: copy your appliances, their order, and EV charging settings to another phone by scanning a QR code or sending a link — no account, works offline. The other phone shows a preview where you can add, replace, or pick what to import.

v6.3 July 13, 2026

Sort and reorder your appliances: drag them into your own order, or sort by most used, recently used, name, duration, or type.
“Most used” and “Recently used” count taps on both your phone and watch.
Choose where vehicles appear among the appliances: mixed in, first, last, or a separate section.
Vehicles now show a car icon, and data sources can be reordered by dragging too.

v6.2 July 12, 2026

Redesigned Settings: a tidy menu of categories, each with an icon and its own screen — Appliances, EV charging, Total price, Region (country, price zone, timezone), Appearance (language, theme), and Advanced. Everything is easier to find than the previous single long list, and returning from a picker keeps your place.

v6.1.1 July 12, 2026

All-in price polish: the surcharge field now shows your currency (e.g. €/kWh), Settings keeps your scroll position when you return from a picker, and it reminds you to choose a supplier or enter a surcharge before leaving if the total price is switched on.

v6.1 July 12, 2026

All-in price (Netherlands): optionally show the full consumer price — the spot price plus energy tax, your supplier’s surcharge, and VAT — instead of the bare market price. Pick your supplier or enter your own surcharge under “Total price” in Settings. It never changes which window is cheapest; it just shows a realistic run cost.

v6.0.1 June 25, 2026

Refined and corrected translations across all supported languages for clearer, more natural wording.

v6.0 June 23, 2026

EV charging: add your car, enter your current and target charge, and SweetSpot finds the cheapest time to plug in and how long it will take.
“Ready by” time: have any appliance or charge finished by a deadline you set.
Power rating: set an appliance’s power in kW so the cost estimate reflects its real consumption.

v5.4 June 22, 2026

New Earlier and Cheaper buttons let you choose a sooner run time when the cheapest window isn’t convenient, and show exactly how much more it costs.
