Gravity! is an educational physics simulator for iOS that allows users to build and interact with custom solar systems and galaxies.
The App DNA
What makes this app unique?
The app removes the cognitive friction of manual physics calculation, allowing users to observe orbital mechanics through direct manipulation of particle mass and color.
For Students and hobbyists interested in physics simulations and basic orbital mechanics.
What does it look like?
Key features
Simulates Newtonian gravity for particles, planets, and black holes with adjustable mass, size, and color parameters.
Allows users to build custom galaxies and solar systems by flinging asteroids and planets into gravitational fields.
Enables zooming and panning across the simulation space using two-finger gestures.
How much does it cost?
Gravity! is distributed as a free educational tool with no observable monetization or in-app purchase gates.
Velocity
Maintenance developmentperformanceShow more...
Gravity! maintains a maintenance-level cadence, with only one release recorded in the analyzed window. The latest update focused on technical refinements to the physics simulation, specifically regarding rotation accuracy. Development appears stable but infrequent, with no evidence of new feature expansion or live-service events. The current pace of approximately one release every two months suggests a focus on long-term stability rather than rapid iteration.

Competitive landscape for Gravity!
How's the Education market?
Gravity! occupies a niche space in the Education category as a free, ad-free physics sandbox. With only 18 total ratings across its lifetime, the app lacks the scale of broader educational tools, and its maintenance-only cadence suggests a hobbyist-led development model.
The rivals identified
The Analyst's Read
Key takeaways for Gravity!
Where is it heading?
The educational physics market is increasingly dominated by tools with structured progression and cloud-sync capabilities. Gravity! remains in a maintenance-mode posture, which exposes it to churn as users seek more stable, feature-rich alternatives. Addressing the stability issues is the only path to preventing total user attrition.
- Frequent application crashes during planet placement disrupt the core gameplay loop, which directly correlates to the mixed sentiment score.
- The latest release (v2.2) focused on physics refinement, indicating that development remains in a maintenance phase rather than an expansion phase.
The SWOT
- Sandbox physics engine allows granular control over orbital parameters like mass and density.
- Visual aesthetics provide a relaxing experience for short-session engagement.
- Implementing an undo function would resolve the primary frustration identified in user requests.
- Automated camera tracking would improve visibility for complex orbital simulations.
Next best moves
Ship crash-reporting and stability fixes because frequent exits during placement are the #1 churn driver → stabilize the core loop.

The lack of monetization is not a weakness but a retention lever, as Gravity!
Read the full takeBottom line
Gravity! relies on its sandbox physics to retain a small, loyal user base, but technical instability threatens this core. Stabilizing the simulation loop would unlock higher engagement, as the current crash rate prevents users from exploring the full depth of the particle engine.
