Stoichiometry is a specialized chemistry utility for balancing reactions and calculating reactant quantities on iOS and Mac.
The App DNA
What makes this app unique?
The tool removes the cognitive friction of manual stoichiometric calculations for students and laboratory professionals.
For Chemistry students and laboratory professionals requiring precise stoichiometric calculations and reaction balancing.
What does it look like?
Key features
Automated balancing of chemical equations including unlimited components and state indexes.
Calculates molar masses, moles, and actual masses of reactants and products based on input quantitative data.
Automatically identifies the limiting reagent when data is provided for multiple components.
Exports reaction data to the Gas Phase Stoichiometry app for pressure and volume calculations.
How much does it cost?
Flat-fee paid model at $2.99, targeting students and professionals requiring specialized chemistry utilities.
Velocity
Dormant developmentopaqueShow more...
Stoichiometry has been inactive for 708 days, placing it firmly in the zombie category. There have been no feature updates, bug fixes, or operational changes recorded in the last two years. The development momentum is non-existent, and the app appears to be in a state of total abandonment.

Competitive landscape for Stoichiometry
How's the Education market?
Stoichiometry occupies a niche utility space in the Education category, relying on a $2.99 paid model rather than ad-supported volume. The lack of recent updates suggests a stable, legacy position rather than an aggressive growth strategy.

Key takeaways for Stoichiometry
Where is it heading?
The education utility market is increasingly favoring freemium models that lower the barrier to entry for students. Stoichiometry remains exposed due to its stagnant release cadence and paid-upfront model, which will likely lead to a gradual decline in relevance as more active, ad-supported rivals capture the student segment.
- The two-year release gap indicates a maintenance-only posture, which limits the potential for new user acquisition in a crowded education utility market.
- High satisfaction from the existing user base suggests the core calculation engine remains functional and meets the needs of its target audience.
The SWOT
- Specialized calculation engine creates a defensible barrier against general-purpose math tools.
- Cross-app integration with Gas Phase Stoichiometry creates a multi-tool acquisition lever.
- Localized pricing could capture students in academic-heavy markets.
