Transform any doorway into a portal to another dimension with one tap. Parents have made Portal Door the centerpiece of block-game themed birthday parties, and kids keep asking to walk through it long after the novelty should have worn off. Point your camera at a doorway, frame the opening, and watch a dimensional glow creep across the threshold — every crossing announced by a sound that echoes from somewhere just beyond the visible. Portal Door is an augmented reality app that uses your device camera to place a glowing portal effect inside any real-world doorway. Nothing to download separately, no special hardware required, no accounts to create. Tap, frame the doorway, step back, and watch. For the party host Hosting a birthday party with a block-game or dungeon-adventure theme? Open Portal Door on a phone or tablet before guests arrive and prop it up near the entrance. A group of kids walking through a full-size glowing portal beats any paper banner or printed decoration — and the only cleanup is closing the app. Parents who've tried it report that the portal becomes the moment the whole party remembers, and that kids keep circling back to walk through it again long after they've moved on to cake. For the AR demo Trying to show someone what augmented reality can actually do? Portal Door is the demo that sticks. While most AR apps overlay stickers on a tabletop, Portal Door turns a real hallway into the effect. Point, frame, step back, watch someone walk through. The reaction is immediate and loud. For the classroom Teachers and after-school educators have used Portal Door to spark conversations about augmented reality, how cameras work, and how devices model three-dimensional space. There's no more vivid illustration of a device "understanding" its surroundings than letting a student walk through a doorway that, on screen, leads somewhere entirely else. For Halloween No decorations required. Set Portal Door running on a tablet near the front door and every visitor steps through a glowing dimensional vortex before they ever reach the candy bowl. No assembly, no power cables, no cleanup once the last guest has gone through. For content creators Video makers have used Portal Door for walkthroughs, reaction shoots, and "what's behind this door?" hooks. Place a phone on a stand at the far end of a hallway, open Portal Door, frame the opening, and you have a visual premise before you've written a single word of script. The reaction shot writes itself. For game night Running a tabletop RPG campaign with a dungeon or portal-jump theme? Open Portal Door on the doorframe of the gaming room before players arrive. Walking through a glowing dimensional rift to reach the table is a level of scene-setting no playlist or printed map can match. What players are saying The highest-rated review in Portal Door's history comes from a parent who set the app up at a block-game themed kids' birthday party. Their verdict: it was super cool, and the kids kept walking back through the door for more. That's the experience Portal Door is built for — the kind of moment that gets talked about on the drive home. Frequently Asked Questions How do I use Portal Door? 1.

Verdict
The clearest difference is rating: Falling Filter at 4.6 against Portal Door's 3.0. Falling Filter also leads on ratings volume (2.3K vs 2) and update cadence (every 5 days vs fortnightly). Portal Door's advantage is in-app purchases (none vs 3) and review sentiment (50% vs 16%). On price, ads, device support and iOS requirement 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. Falling Filter sells 3 in-app purchases, starting at $4.99 per 7 days. Portal Door asks for nothing beyond the download.
Falling Filter holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Falling Filter has 2.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Portal Door's written reviews are positive against 16% of Falling Filter's, so the app with the better star average is not the one people write more warmly about.
Portal Door ships an update fortnightly, Falling Filter every 5 days. The most recent releases landed on October 2, 2026 and October 16, 2026 respectively.
