Why people go looking in the first place
Three reasons come up again and again when people ask about moving away from Lazy Lighting, and none of them is "the app is bad".
The first is hardware. Lazy Lighting ships only for iPhone and iPad, and its App Store listing requires a recent version of iOS or iPadOS. If the device you carry is an Android phone, or the machine already sitting in the venue is a Windows laptop, the app is not an option. Searches for Lazy Lighting Windows are common for exactly this reason — and the honest answer is that there is no Windows build, so the real question is what runs on Windows and does the same job.
The second is the shape of the surface. Corner pinning a video onto a flat garage door is easy. Wrapping it around a bay window, a pillar or a curved shopfront is not, and that is where the depth of an app's warping tools starts to matter more than its effects library.
The third is money, and it is usually about the shape of the payment rather than the amount — a small one-off purchase, a subscription you can cancel after Halloween, or a licence you buy once. Every app here answers that differently.
What Lazy Lighting genuinely does well
A comparison that pretends the incumbent is useless is no use to anyone. Lazy Lighting is a well-built iPhone and iPad app aimed at people who want a light show without a computer. It gives you cut, mask and warp tools, a Draw mode for making visuals live, video and custom logo import, and an effects library with kaleidoscopes, tunnels and colour morphs. It outputs over AirPlay as well as wired HDMI, USB-C and Lightning.
The feature that earns it the most loyalty is the dual channel setup: two independent layers you can mix and cross-fade while the show is running. For a band playing behind a mapped backdrop, or someone driving a house display live on Halloween night, that beats apps which only play one clip at a time. The app is free to download and sells its features through in-app purchase tiers; check the App Store listing for what those tiers cost today.
If you own an iPhone, you are happy with those tiers, and you never need to open the project on anything else, there is no strong technical reason to move.
The comparison at a glance
The price column describes how each app charges, not what it costs — in-app tiers and licence prices move, so read the store listing before you buy. "Mesh warping" here means subdividing a surface and pushing individual points, as distinct from dragging four corners.
| App | Platforms | Mesh warping | Price model | Best for |
|---|---|---|---|---|
| Lazy Lighting | iPhone, iPad (iOS 17+) | Warp, cut and mask tools | Free download + paid in-app tiers | Live two-channel shows and holiday displays on Apple hardware |
| ILW Light Mapper | iPhone, iPad, Mac (M1 or later) | Four-point pin plus Warp Painting (localised distortion) | Free download + paid in-app tiers | Low-cost route on Apple devices; wall art and room installs |
| Optoma Projection Mapper (was DynaMapper) | Android, iOS, Amazon Fire | Rectangles with bezier-curvable sides; no point-level mesh | Free, with paid content packs | Free first attempt, flat panels and gently curved surfaces |
| HeavyM Remote | iOS, Android (remote only) | Handled by HeavyM on the desktop, not the phone | Free app; requires a HeavyM desktop licence | People who already run HeavyM on a laptop and want a walk-around remote |
| SurfaBeam Pro | Android, iOS, macOS, Windows (.exe, Microsoft Store, Steam) | Yes — mesh warping plus corner pinning and masking | Free edition; Pro monthly, quarterly, yearly or lifetime — one-time DLC on Steam | Mixed-device teams, curved geometry, tracking and timed shows |
| Desktop VJ software (Resolume, MadMapper, HeavyM) | Windows, macOS | Yes, extensive | Paid licences, typically the most expensive option here | Large permanent installs, multi-projector blends, show control |
The alternatives, app by app
ILW Light Mapper
If you searched for a light mapper app or lightmapper app and landed here, this is probably what you were after. ILW Light Mapper is free to download on iPhone, iPad and Apple Silicon Macs, and sells its unlocks as low-cost in-app purchases.
For the price it is a serious tool: multiple grids for complex setups, four-point corner adjustment, global offset, touch scale and rotation, and a Warp Painting mode that paints localised distortion into an area rather than nudging the whole quad. Masking is additive and subtractive, and you get hue, saturation and brightness controls, playback speed, transparent-black keying, timeline scrubbing, undo, and multiple named save slots. Content comes from your own H.264 MP4 files or an in-app library.
The catch is the same as Lazy Lighting's: it is Apple-only. If your team is mixed, or you need to hand a project to someone on Android or Windows, it does not solve that. But if everyone involved is on Apple hardware, it is cheap enough and capable enough to be worth trying before you spend more anywhere else.
Optoma Projection Mapper (formerly DynaMapper)
Worth clearing up first: DynaMapper and Optoma Projection Mapper are the same app. Reo Tek's DynaMapper was rebranded under the Optoma name, which is why an old bookmark usually redirects to the Optoma listing.
It is free, runs on Android, iOS and Amazon Fire tablets, and works with any projector — you do not need Optoma hardware. You get rectangular surfaces plus a rectangle whose sides bend into bezier curves, which beats a plain four-corner keystone and handles arched doorways and gentle curves well. There is a built-in material pack for colours and textures, plus optional themed content packs.
Where it stops is point-level control. Bending an edge is not the same as subdividing a surface and pushing individual vertices, so a column, a car bonnet or a stone façade will fight you. The current release also has no tracking or timeline sequencing. For a free app that is a fair trade, and it is still the sensible first install if you have never mapped anything.
HeavyM Remote
Frequently misunderstood, so plainly: HeavyM Remote is not a mapping app. It is a companion remote for HeavyM, which runs on a Windows or macOS computer. Install it on its own and there is nothing for it to control — the mapping engine lives on the desktop.
Judged for what it is, it is good. HeavyM itself is capable desktop software with a strong generative visuals library, and being able to walk to the far side of a room and trigger scenes from your phone removes the most annoying part of desktop mapping — the constant walk back to the laptop to nudge one corner. If you already own HeavyM, do not switch apps; install the remote. If you do not, you are buying into a laptop workflow and a desktop licence, which is the opposite of what most people in this search want.
SurfaBeam Pro
Full disclosure: this is our app, so weigh what follows accordingly and test it yourself rather than taking our word for it.
The reason SurfaBeam belongs in this list is platform coverage. It runs on Android, iOS, macOS and Windows — and on Windows there are three ways in: a direct .exe installer, the Microsoft Store, or Steam, where the base app is free and Pro is a one-time DLC purchase rather than a subscription. That last route answers the "Lazy Lighting for Windows" question most directly.
The toolset covers mesh warping, corner pinning, digital masking and multi-surface mapping, with MP4 and PNG import, touch- and sound-reactive effects, hand, body and object tracking, visualizers, and a Timeline editor for sequencing a show rather than looping a clip. Output goes over AirPlay and Chromecast, or USB-C and Lightning to HDMI for a wired feed. The SurfaBeam user guide walks through each panel with screenshots if you want to see the interface first.
The honest trade-off is the free edition. It includes the whole mapping, media, effects, tracking, visualizer and Timeline toolset, but it puts a watermark on the projected image and on exported video, shows an entry gate before mapping (subscribe, or watch a rewarded ad on Android), and reserves saving and loading project files for Pro. That is fine for testing and for a one-off evening. It is not fine if you need to reopen the same alignment next week — for a repeatable install you need Pro, which removes the watermark and the gate and unlocks Save, Load and Export including Map Export to PNG for After Effects.
Try it on whatever you already own
SurfaBeam installs on Android, iOS, macOS and Windows. Map your hardest surface first, then decide.
A word on "light mapper" and other confusing search results
Two separate things share this vocabulary, and mixing them up wastes an evening.
The first is projection mapping: a projector throws light onto a surface and software bends the image to fit. That is what every app above does. The second is pixel mapping for addressable LED strings — software that decides which bulb on a roofline turns which colour, driving physical lights rather than a projector. Both get called "light mapping", and the search results blend them.
The test is simple: if your output plugs into an HDMI port, you want a projection mapping app. If it plugs into a light controller, you want pixel-mapping software and nothing here will help. Names such as ProjectX projection mapping also surface in these searches; before committing an evening to an unfamiliar tool, open its store listing and check the last update date and the supported platforms rather than trusting a video thumbnail.
How to choose a Lazy Lighting alternative
Answer these in order and the choice usually makes itself.
- What device will be in your hand on site? If the answer is anything other than an iPhone or iPad, Lazy Lighting and ILW Light Mapper are out, and you are choosing between Optoma Projection Mapper and SurfaBeam.
- Is the surface flat? A garage door or a plain wall is a solved problem — the free Optoma app will do it. A pillar, a bay window or a car needs point-level mesh warping.
- Do you need the same alignment again next month? Then you need saved project files, which means Pro on SurfaBeam or a paid tier elsewhere. Re-aligning a house from scratch every night is miserable.
- Is the show timed or improvised? Live with a band: Lazy Lighting's dual channels suit that well. Timed to a soundtrack: you want a Timeline.
- Do you already own desktop software? If HeavyM, Resolume or MadMapper is already paid for, add the remote rather than replacing the workflow.

A 20-minute test before you commit to anything
Every mobile app here is free to download, and the desktop packages ship trial or demo builds, so there is no reason to buy blind. Run the same test in each candidate and the differences surface fast.
- Start with your hardest surface, not your easiest. Everything maps a flat wall. Point the projector at the thing you actually care about.
- Lock the projector down first. Rotate the head by one degree at a four-metre throw and the image moves about seven centimetres on the wall. Clamp or weight it before you align anything.
- Project a plain white rectangle before any content. Content hides misalignment; a flat white fill shows exactly where the edges spill.
- Pull one edge into a curve and count your control points. Four corners, a bezier edge and a subdivided mesh feel identical on a flat wall and completely different on a curved one.
- Mask one real obstacle — a window, a doorframe, a downpipe — and check whether the mask survives when you then adjust the warp.
- Save, quit the app fully, and reopen. The step people skip and regret. On SurfaBeam's free edition this is where you hit the Pro wall, which is deliberate but worth knowing in advance.
- Check your output path last. AirPlay and Chromecast are fine for ambient loops but add latency you will notice on beat-synced content; wired HDMI is safer for anything timed. Our AirPlay setup walkthrough covers keeping wireless usable.
On brightness, the usual rule holds whichever app you pick: roughly 3,000 lumens is comfortable indoors in a dimmed room, and 4,000 to 6,000 lumens is more realistic outdoors. No software compensates for a projector that is too dim for the space. If this is your first map, the beginner's guide to digital mapping covers corner pinning and grid warping step by step, and the holiday projection guide deals with mapping a house exterior.
Frequently Asked Questions
What is the best Lazy Lighting alternative for Windows?
Lazy Lighting is an iPhone and iPad app, so there is no Windows version of it to move to. Of the apps in this comparison, SurfaBeam is the one that runs on Windows as well as Android, iOS and macOS. On Windows you can install it three ways: a direct .exe installer from the SurfaBeam site, the Microsoft Store, or Steam — where the base app is free and Pro is a one-time DLC purchase rather than a subscription.
Is there a Lazy Lighting alternative for Android?
Yes. Lazy Lighting itself is iOS and iPadOS only. On Android the two realistic choices are Optoma Projection Mapper, which is free and handles rectangular and bezier-edged surfaces, and SurfaBeam, which adds mesh warping, masking, tracking and a Timeline editor. SurfaBeam is listed on Google Play as a free edition and a separate Pro edition.
What is the difference between a light mapper app and a projection mapping app?
In practice the two terms overlap. Apps marketed as a light mapper app — ILW Light Mapper is the clearest example — do the same job as a projection mapping app: they align video or images to a real surface using a projector. The confusion comes from a separate category of software that maps addressable LED pixel strings for Christmas light displays. If your output device is a projector, you want a projection mapping app.
Is DynaMapper still available?
DynaMapper was renamed. The same app from Reo Tek is now published as Optoma Projection Mapper for Android, iOS and Amazon Fire devices, which is why searches for DynaMapper usually land on that listing. If you used DynaMapper a few years ago, the current Optoma release is its direct continuation rather than a different product.
Can I try SurfaBeam before paying for it?
Yes. The free version includes the full mapping, media, effects, tracking, visualizer and Timeline toolset. It adds a watermark to the projected image and to exported video, shows an entry gate before you start mapping — subscribe, or watch a rewarded ad on Android — and reserves saving and loading project files for Pro. Pro removes the watermark and the entry gate and unlocks Save, Load and Export, including Map Export to PNG for After Effects.
Map from the device you already carry
SurfaBeam runs on Android, iOS, macOS and Windows, with mesh warping, masking, tracking and a Timeline editor in every edition. Install the free version, run the 20-minute test above on your hardest surface, and decide from there.
