Simulon Reality-Aware Rendering: is it free, and how does it actually work?

By Era of Minds ·

Short answer

Simulon is free to download and every new account gets 100 one-time starter credits to try Reality-Aware Rendering with assets from the Simulon Library. That is a trial, not a free tier you can live on: free video exports are 480p and personal use only, and making your own characters from a photo or sketch needs Plus at $14.99 a month or Pro at $39.99. Renders take a couple of minutes in the cloud, the result is regenerated (so timing can shift from what you filmed), and it is iPhone only for now. Simulon does not publish how many credits one render costs.

What is Simulon Reality-Aware Rendering?

Simulon is an iPhone app from Beamm Technologies Inc., a Delaware company that trades as Simulon. It started in October 2025 as an in-camera VFX tool for placing 3D models into real footage, and the rebuilt Simulon 2.0 arrived on October 9, 2026. The app turns words, a photo or a sketch into a "neural asset", a 3D subject you can drop into your room with AR, film, and then animate by describing what happens next.

Reality-Aware Rendering is the new part. In founder Divesh Naidoo's launch post, you place the assets with your phone and act out the scene. When you stop recording, Simulon "renders the take, reading everything in it (what you do, what you say and the place around you), and your assets respond to all of it." The App Store version history lists it in version 2.1.0, alongside share links and Spaces.

The key line is the last one: "The final is regenerated from your recording: a new performance of the scene, not a copy of the footage." That is what makes the demos look so natural, and it is also the main catch, which we get to below.

Why is Simulon going viral on X?

Naidoo posted the launch on October 28, 2026 at 16:16 UTC (20:16 Dubai) with a short demo film of neural assets reacting to the person in the scene. When we checked through the X API on the morning of October 29 (Dubai):

  • @diveshnaidoo: 613,169 views, 8,466 likes, 5,553 bookmarks, 1,314 reposts and 524 replies. That bookmark count is high; people are saving it to try.
  • @LinusEkenstam quoted it as "ground breaking technology": 108,179 views and 831 bookmarks.
  • @Simulon, the company account: 39,242 views. A follow-up from Naidoo saying "You can try this right now for free" drew 24,574 views and 140 bookmarks.
  • Post volume: posts mentioning Simulon or reality-aware rendering went from 1 on October 27 to 1,140 on October 28 (UTC), and another 1,123 by 06:24 UTC on October 29. It is still climbing.

The most common replies under the launch? "When Android?" and "Is it free?" So that is what we checked.

Is Simulon free?

Partly. Here is what the pricing section and the Plans and Credits page say:

  • Free: 100 starter credits when you join. They are "a one-time gift, not a monthly refill", they work with subjects from the Simulon Library, and they don't expire while your account is open. Exports: images up to 1080p, video at 480p. Use: personal, non-commercial.
  • Simulon Plus, $14.99 a month: a monthly credit allowance, custom subjects from words or images, and commercial use for individuals.
  • Simulon Pro, $39.99 a month: three times the monthly usage of Plus, up to 15% off top-ups, "studio-tier" video and commercial use for businesses.
  • Top-ups (Plus and Pro only): 100 credits for $4.99, 260 for $12.99, 500 for $24.99. Bought credits never expire; the monthly allowance does not roll over.

So the honest answer: you can try Reality-Aware Rendering for free with library assets, but the "bring your own character" part in most of the demos is paid.

How many credits does one render cost?

Simulon doesn't say. The site and terms only promise that "the app shows how many Credits an action will use before you confirm it." Neither page lists how many credits Plus or Pro include each month either. A user asked under the launch post how many credits Pro gives and called it "not transparent enough", and Naidoo replied on October 29 that they will add "a breakdown that shows what each task costs in the app as there are a few different things that require different levels of compute."

Two rules in the terms are worth knowing before you spend anything: a render that fails on Simulon's side or gets blocked by its safety filters costs nothing, but if you cancel a render yourself you pay for the credits it already used.

One more source of confusion: the App Store listing shows ten in-app purchase items, including names like Core ($29.00), Studio ($200.00) and Lite ($15.00) that are not on the current pricing page. Simulon's 2025 launch had Core, Pro and Studio plans, so these look like older plans still in the listing. We couldn't confirm which ones are still sold, so go by the prices the app shows you.

How does Reality-Aware Rendering work?

From the launch posts and the app description, the flow looks like this:

  1. Make or pick an asset. Choose one from the Simulon Library (free) or create one from a photo, sketch or text (Plus or Pro).
  2. Place it in AR. Set its size and position in your room, then move the phone to frame the shot.
  3. Act out the scene and record. Move around it and talk to it; the launch post says the render reads what you do, what you say and the place around you. The app tracks the phone with the gyroscope, accelerometer and compass and records sound if you allow the microphone.
  4. Stop and wait. The clip goes to the cloud. Naidoo says it "takes a couple minutes to reason and render". It is not real time yet.
  5. Get a regenerated video. The asset reacts to your actions, your words and the light in the room.

Simulon's AI and Your Content page explains the back end in general terms: a language model turns your input into detailed instructions, an "AI infrastructure provider" runs the image, 3D or video model, and for some models the request goes on to the company that built it. Simulon doesn't name these providers on the page; it says you can email privacy@simulon.com to get the current list. The privacy policy also says the app does not currently use the iPhone's LiDAR depth sensor.

Naidoo posted side-by-side clips of the finished short and the raw footage, and said the whole short was made "with zero prompting".

What's the catch with a regenerated video?

Because the final clip is generated again, it is not a frame-accurate copy of what you filmed. A viewer pointed out that the hand in the final version moved out of sync with the live hand. Naidoo confirmed that "retiming and some changes in the interactions occur" and said they could stay closer to the original video "at the expense of realism", maybe as an option later.

For a fun short, that doesn't matter much. For anything where you need your exact performance (a client shot, lip sync, a precise product move) plan on checking every take.

Two smaller things to know:

  • AI labels stay on. Images get C2PA content credentials and an invisible watermark, and videos "may also carry an invisible watermark". There is no visible watermark, but the terms ask you not to strip them, and the free plan's social-posting permission depends on keeping them.
  • Your audio leaves the phone. If you allow the microphone, the sound in your clip goes with it to Simulon's AI providers so they can make the video. Simulon says it does not train models on your content and does not create voiceprints.

Is Simulon on Android?

No. Both simulon.com and the launch post say Android is "coming soon", with no date. Dozens of replies under the launch ask the same thing. On Apple devices, the App Store listing says iOS 17.0 or later for iPhone and iPadOS 17.0 for iPad, while Simulon's own llms.txt file says iOS 18.6 or later. If your phone is on an older iOS, update first.

There is also a desktop companion, Simulon Hub for macOS and Windows, which uploads custom .usdz and .glb assets and connects to Blender 4.4.3 or newer. You don't need it for Reality-Aware Rendering.

Can you use Simulon videos commercially?

Only on a paid plan. Section 8 of the terms says the free plan is for personal, non-commercial use, "including posting them on your own social media accounts, as long as the content credentials and watermark stay in place." Monetised posts, sponsored content, client work and ads need Plus or Pro. Anything you make on a paid plan keeps its commercial rights even if you downgrade later.

Simulon says it does not claim ownership of what you make, though it warns the law on owning AI-generated content is still unsettled. You must be 13 or older to use it, and under-18s need a parent's permission.

Should you try it?

If you have an iPhone and want to see the demo effect for yourself, yes: it costs nothing to download and spend the 100 starter credits on a library creature. Just treat it as a trial. If you want your own character, commercial rights or video above 480p, you are looking at $14.99 a month at least, and until Simulon shows per-render costs it is hard to know how many clips that buys.

We did not install or run Simulon for this article; we don't have the app on a test iPhone. Everything above comes from Simulon's site, terms, privacy policy, the App Store listing and the founder's posts.

It is the same pattern we saw with Hi3D's "RIP Blender" photo-to-3D post and Cindy's "free" agent app: the clip is real, and the pricing page has the rest of the story. If you want more iPhone AI tricks, our Hey Grok on iPhone guide covers a free one.

FAQ

What is Simulon Reality-Aware Rendering?

It is a rendering mode in the Simulon iPhone app, announced on October 28, 2026. You place a 3D neural asset in your room with AR, then act out a scene around it. When you stop recording, Simulon reads what you did, what you said and the space around you, and generates a new version of the clip in which the asset reacts. The final video is regenerated from your recording, not your footage with a model pasted on top.

Is Simulon free?

The app is free to download and new accounts get 100 starter credits. Those are a one-time gift, not a monthly refill, and they only work with subjects from the Simulon Library. The free plan exports images up to 1080p and video at 480p, for personal, non-commercial use. Making your own assets from a photo, sketch or text needs Simulon Plus ($14.99 a month) or Pro ($39.99 a month).

Can I use Reality-Aware Rendering on the free plan?

The founder posted that you can try it right now for free, and the free plan includes starter credits for library assets. Simulon does not publish how many credits one Reality-Aware render uses, and the founder said on October 29 that a per-task cost breakdown will be added to the app. We did not test how many renders 100 credits buy.

How long does a Simulon render take?

Not real time. The founder replied on X that Reality-Aware Rendering takes a couple of minutes to reason and render after you stop recording, and that real time is the goal. Processing happens in the cloud, so you need a connection for the render itself.

Is Simulon available on Android?

Not yet. Simulon's site and the founder both say Android is coming soon, with no date. Right now it runs on iPhone and iPad; the App Store listing says iOS 17.0 or later, while Simulon's own llms.txt file says iOS 18.6 or later, so check your iOS version.

Does Simulon train AI on my videos?

Simulon's AI and Your Content page says it does not use your scenes, photos, prompts or recorded clips to train or fine-tune generative AI models, and that any change would come with 30 days' notice and an opt-in. Your files are sent to its AI infrastructure provider and some model makers to produce the render. If you allow the microphone, the sound in your clip goes to those providers too.

Can I use Simulon videos commercially?

Only on a paid plan. The free plan is for personal, non-commercial use, including posting on your own social accounts with the content credentials and watermark kept in place. Monetised posts, sponsored content, client work and ads need Plus or Pro, and work made on a paid plan keeps its commercial rights if you downgrade later.
