We didn’t have time to compile our typical roundup of the best paid iPhone and iPad apps on sale for free on Tuesday, so we’re making up for it with a particularly great list today. The star of the show is TapMeasure, which might be the coolest ARKit app we’ve ever seen, but there’s plenty more to be excited about in today’s post. Check out all the apps below, and hurry to be sure you download them before these sales end.

This post covers paid iPhone and iPad apps that have been made available for free for a limited time by their developers. BGR is not affiliated with any developers. There is no way to tell how long they will be free. These sales could end an hour from now or a week from now — obviously, the only thing we can guarantee is that they were free at the time this post was written. If you click on a link and see a price listed next to an app instead of the word “get,” it is no longer free. The sale has ended. If you download the app anyway, you will be charged by Apple.

TapMeasure

Normally $1.99.

Meet TapMeasure, the spatial utility that combines computer vision and AR, creating a whole new way to capture and measure your space. ▶ 3D Room Builder

Create scale-accurate 3D models of rooms that you can measure and review immediately, or revisit later. ▶ Quick Measure

Capture point-to-point measurements with just two taps. ▶ Smart Level

Ensure picture frames and artwork are perfectly level, automatically. TapMeasure is the fastest, smartest way to measure a physical space. Period. Additional Features: • Geometric Recognition: Automatically detect rectangular objects like doors, windows, artwork, and more, and add them to your model. • Quick Outlining: Create simple outlines of items on the walls or floor. • Easy Sharing: Send your 3D model to anyone with a simple URL. • SketchUp Export: Export your 3D model as an .SKP file, allowing you to view and edit in both free and pro versions of SketchUp. We built TapMeasure as an easy to use, everyday spatial utility — but it also works great for pros, including interior designers, architects, contractors, real estate agents, appraisers, insurance agents, and anyone that needs quick, approximate 3D models and measurements. TapMeasure combines the new ARKit framework in iOS 11 with advanced computer vision, to recognize and track objects. Since TapMeasure uses ARKit, you’ll need an ARKit-compatible device (iPhone 6s or newer). TapMeasure is built by the team at Occipital (occipital.com). We’re the same team behind 360 Panorama, Structure Sensor, Canvas, Bridge, and other spatial computing products. We can’t wait to see what you create with TapMeasure!

Vikings: an Archer’s Journey

Normally $1.99.

Nott, a Valkyrie with a tenacious character, has incurred the wrath of the Viking gods who, as punishment, have sent her loyal wolf Oder into the Underworld. At a loss without her loyal companion, Nott goes in search of him within the cold and misty dwelling of the deceased known as “Helheim”. Fortunately, Nott is a formidable archer, so she’ll be able to collect special arrows along the way to help her overcome the evil monsters drawn straight from Nordic legends.

Along her journey, Nott will also have to gain the support of several Viking heroes fallen in battle. They will help her complete her Odyssey, and in return, once reunited with Oder, Nott and her faithful companion will get them out of hell. With its minimalist graphic style, this mix between a “shoot ’em up” and “infinite runner” game will delight a whole range of players: the game is easy to learn but difficult to master! Features: • Gameplay based on precision (arrow firing) and quick reflexes (infinite runner feature).

• Random level generation: a new game experience each time.

• Simple controls: easy to learn, but difficult to master

• Collect the different firing power-ups (Bullet Time, Multi-Arrows, Explosive Arrows and Target Help)
