Know which plan actually fits your home.
Wattlark replays your own usage against flat, time-of-use and dynamic plans, so the comparison reflects when you really use power rather than a national average.
Evening Saver would have cost $49 less
Your last 30 days, priced on three plans.
Four behaviours, each visible in the app and recorded in the household activity log.
Replay on real usage
Every hour of your last month is repriced under each plan, with solar and battery behaviour included.
Weekday and weekend
Weekend peaks are different on many plans. The heatmap shows exactly when each price applies.
Standing charges visible
Fixed charges are shown next to unit rates so a cheap rate does not hide an expensive plan.
You decide
Wattlark shows the comparison. Switching plan stays a decision you make with your supplier.
