ORBIT is a gravity simulator at the heart of a puzzle game. Launch planets with a flick of your finger, and try to get them into stable orbits around black holes. Can you make enough orbits to progress to the next level? New: ORBIT now features a Sandbox (paid) where you can create your own levels! Control time, disable collisions, and paint with gravity. Publish your creations to the world for everyone to play. • 45 free levels, with new mechanics are introduced over time — like repulsive black holes and planets with their own gravity that attract each other • Play community-created levels — virtually limitless content made by other players, all completely free • Launch as many planets as you like, and watch the mesmerizing orbital mechanics unfold • Planets leave colored traces, so that at the end of a level you will have created a beautiful piece of art • See the future trajectory of a planet before you launch it • Play in an environment of smooth, minimalist graphics while listening to relaxing classical piano Follow on Twitter: https://twitter.com/highkeygames Follow on Facebook: https://www.facebook.com/highkeygames
Delta
Read full descriptionHide full description
Pilot through ten star systems on a single trajectory. Aim, launch, slingshot — gravity does the rest. Delta-V is a one-finger arcade puzzle. Pull back from your launch pad to aim and set power, release to launch. Then ride momentum through dense star systems — bend your path around planets, slingshot off moons, scan exotic gravity wells, and dock at the next port before your fuel runs dry. Every system tells a story. Every system raises the stakes. ONE-FINGER FLIGHT • Tap and drag from the ship to aim and set power • A live trajectory preview shows the gravity-bent path before you commit • Mid-flight: tap anywhere to fire navigation thrusters perpendicular to your heading • Toggle between system overview and ship-follow camera mid-flight TEN STAR SYSTEMS, ONE STORY A handcrafted arc from HIKARU RELAY to THE BEACON. Each system is procedurally seeded but story-narrated — broken comms relays, pirate sieges, derelict mining stations, a black-hole gauntlet, a final stand at the edge of charted space. DYNAMIC OBJECTIVES Every system asks something different: salvage cache fragments, gravity-scan a target planet, slingshot off a named world, bump a specific moon, earn credits the hard way, or finish a leg without spending a single thruster correction. Bonus credits stack up. UPGRADE YOUR SHIP Spend earned credits at any starport's shop. Four branches, three tiers each: • Hull — more damage absorbed before you go down • Propulsion — bigger fuel reserve and stronger thrusters • Shields — softens hits from pirates, asteroids, atmospheres • Weapons — auto-turret range, fire rate, plasma damage LIVE GRAVITY PHYSICS Real n-body gravity from stars, planets, moons, and black holes. Every flyby bends you. Plan the path you can't directly fly. Slingshots earn bonus credits the tighter your scan angle. LOST IN SPACE Out of fuel and drifting? You'll get a four-second warning before the run ends — enough time to decide whether to push the brake button or let the cosmos claim another pilot. SYNTHWAVE EVERYTHING All visuals drawn at runtime in vector code. All sound — every ping, every chord, every drone — synthesized live. No bitmaps, no recordings. Pure offline arcade. Save persists locally. Pause anytime. Restart any system from the pause menu. Navigate gravity. Survive space.

Verdict
The clearest difference is in-app purchases: Delta at none against Orbit's 7. Delta also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
