What is Nightfall?
Nightfall is a free, open-source macOS utility focused on dark mode toggling and scheduling. It sits in your menu bar and gives you a clean, fast way to switch between light and dark mode.
Key features:
- Toggle dark mode via menu bar icon or keyboard shortcut
- Schedule switching at sunrise/sunset or custom times
- Minimal interface that stays out of your way
- Open-source code available on GitHub
- Actively maintained (v3.1, August 2024)
Nightfall does one thing and does it well. If all you need is a dark mode toggle with scheduling, it is hard to argue with free and open source.
What is Solace?
Solace is a macOS menu bar app that combines dark mode scheduling with colour temperature control, wallpaper management, and weather-aware switching.
Key features:
- Dark mode scheduling (solar, custom times, or weather-aware)
- Evening warmth (built-in colour temperature reduction)
- Wallpaper sync (separate wallpapers for light and dark mode)
- Global keyboard shortcut
- Multi-display support
- Zero data collection
- One-time purchase ($4.99, no subscription)
Solace takes a broader approach. Rather than handling dark mode alone, it manages several aspects of your Mac's visual environment from a single menu bar app.

When to choose Nightfall
Nightfall is the better choice if:
- You only need a dark mode toggle and schedule — nothing more
- You prefer free, open-source software
- You want the lightest possible footprint
- You already use Night Shift for colour temperature and just need a dark mode scheduler alongside it
Nightfall is excellent at what it does. It is minimal, transparent, and costs nothing. If dark mode switching is the only problem you are solving, there is no reason to pay for more.
When to choose Solace
Solace is the better choice if:
- You want colour temperature control alongside dark mode scheduling
- You want different wallpapers for light and dark mode that switch automatically
- Weather-aware switching appeals to you (dark mode when it is overcast, light mode when it is sunny)
- You want one app instead of running Nightfall + Night Shift + a wallpaper tool separately
The practical difference: Nightfall handles dark mode. Solace handles dark mode, colour temperature, wallpapers, and weather in a single app. If you would otherwise need to run multiple tools, Solace consolidates them.
The verdict
Nightfall is a great free tool for dark mode toggling and scheduling. If that is all you need, use it. If you also want colour temperature control, wallpaper syncing, and weather-aware switching without running multiple apps, Solace brings it all together for $4.99.
Neither app is objectively better. The right choice depends on how many features you actually need.

Frequently asked questions
Is Nightfall really free?
Yes. Nightfall is completely free and open source. The source code is available on GitHub, so you can review exactly what it does. There are no hidden costs, subscriptions, or in-app purchases.
Can Nightfall control colour temperature?
No. Nightfall only toggles and schedules dark mode. It does not adjust your screen's colour temperature. For that, you need Night Shift (built into macOS) or a third-party tool like Solace, which includes built-in evening warmth alongside dark mode scheduling.
Is Solace open source?
No. Solace is a paid app ($4.99, one-time purchase). Its source code is not publicly available. However, its privacy policy is transparent and verifiable: Solace collects no data, has no analytics, and processes location information entirely on your device.
Does Nightfall sync wallpapers?
No. Nightfall does not manage wallpapers. It only handles dark mode toggling and scheduling. If you want different wallpapers for light and dark mode that switch automatically, you need a separate tool like Umbra or an all-in-one app like Solace.
Which app uses fewer system resources?
Both are lightweight menu bar apps. Nightfall is minimalist by design and uses very little memory or CPU. Solace does more (weather monitoring, wallpaper management, colour temperature) but is still a lightweight native macOS app. Neither should noticeably affect performance.
