Use Twin on your Apple iPhone or Apple iPad to scan your item 2. Use Twin on your Apple Vision Pro to place your digital twin That's it! - Your Twin models will be visible even when fully immersed in a visionOS environment, scan in your keyboard and actually see what you're typing on - Your Twin models are created using photogrammetry so they keep their real-world size, bring your favorite things with you into visionOS - Your Twin models can create fun twists on your world, mix and match the real world and the virtual world to your heart's content Please note: • Scanning on iOS and iPadOS requires a device with LiDAR and an A14 Bionic chip or later – this generally means an Apple iPhone Pro released in 2020 or later, or an Apple iPad Pro released in 2021 or later • Models are not tracked, they are not linked to a real world object, and they are stationary – place the stationary Twin model over your stationary real-world objects or wherever you desire • You must be signed into the same Apple ID across your devices – sign into the same account on your Apple iPhone/Apple iPad that creates the scans as well as on your Apple Vision Pro to place the models Twin's Features: 1. Use the photogrammetry capabilities of Twin on iOS/iPadOS to create 3D models (photogrammetry models require a minimum of ten pictures and can use up to a maximum of 200 pictures, pictures must be taken from different angles) 2. Filter your models to bring them to life in entirely new ways – create new colorways or use a filter on your stuff that would be impossible in the real world 3. In the Twin app models are automatically synced between devices signed into the same Apple ID 4. Search, sort, favorite, and rename your 3D models to organize them the way you want 5. Browse your 3D models on your Apple iPhone/Apple iPad or truly see them come to life as you browse and place them in 3D on your Apple Vision Pro WARNING: Photogrammetry works well with some objects and doesn't work at all with other objects, failure to follow these guidelines may result in a failure to create 3D models from your objects. OBJECTS THAT WORK: Solid, non-reflective, evenly lit objects that are less than 4 feet in all dimensions (width, height, depth) OBJECTS THAT DO NOT WORK: Transparent, shiny, monochromatic, unvaried texture, casting shadows objects that are greater than 4 feet in any dimension (width, height, depth) Bring your physical world into your visionOS spatial computing digital world with Twin!

Verdict
The clearest difference is review sentiment: Twin at 75% against Deadline Tracker's 0%. Deadline Tracker's advantage is rating (4.5 vs 4.0). On price, ratings volume, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Deadline Tracker sells 3 in-app purchases, starting at $1.99 per month and Twin sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Deadline Tracker holds the better App Store score, 4.5 against 4.0. Both are backed by a comparable volume of ratings — 10 and 4 respectively. Written reviews complicate that: 0% of Deadline Tracker's written reviews are positive against 75% of Twin's, so the app with the better star average is not the one people write more warmly about.
Deadline Tracker ships an update every 9 days, Twin fortnightly. The most recent releases landed on October 21, 2026 and October 5, 2026 respectively.
