Why themes are a one-time purchase
WindowWise has no ads, no subscriptions, no analytics tracking
you across the web, and no premium tier that gates the features
that actually help you save energy. The app is fully usable on
the day you install it and stays that way.
Each photographic theme takes weeks of work — sourcing or
commissioning the original images, hand-grading variants for
every time of day, every weather, and every season (20 variants
per theme), and tuning the in-app animation so the lighting
shifts feel like part of the landscape rather than a slideshow.
A theme purchase is the way to support that work.
What you get with a theme
Each paid theme ships with 20 hand-graded variants covering
five times of day (dawn, full day, golden hour, dusk, night)
across two weather states (clear and overcast) and two seasons
(summer and winter). The app picks the right variant for the
current conditions and cross-fades smoothly between them as
the day progresses.
Themes are pure visuals — they don't change the engine's
window-opening recommendations or notification timing. They're
cosmetic, on purpose.
More themes coming
The catalog grows over time. Future themes are likely to
include high-altitude mountain landscapes, Mediterranean
coast, desert canyon, and seasonal one-shots (Halloween, mid-
winter, spring bloom). Each release is announced via the
app's update notes — there's no push notification spam.
