the daily ritual
Today
One molecule and one element, alive on arrival. A rotating specimen every day.
Chemistry · for iOS
The invisible world, lit from within.

the deep dive
Five universes · one app
Not a reference book. A studio.
Every screen is built to be touched — atoms you can rotate, beakers that fill, spectra you can scrub. Chemistry, made luminous.
the whole periodic table
Elements
118 elements with a live trend lens. Pinch-zoom from icon grid to data card; eight recolor lenses from electronegativity to density.
a specimen gallery
Molecules
352 molecules as liquid-glass specimen plates. 2D explorable structures, view-in-3D, AR Quick Look, and a Chemical Space star map.
a lab in your pocket
Lab
25 living calculators arranged as instruments — beakers that fill, particle boxes that respond, a pH spectrum you can scrub.
one field, everything
Search
Elements, molecules, formulas, and tools in one iOS-native search. Type a formula, get an instant molar mass.
Elements
the deep dive
Bohr model, quantum probability cloud, emission spectrum, isotope makeup, ionization ladder — and a shareable poster for every element.
The Lab · 25
Living calculators,
not a form dump.
Tools arranged as instruments. An ideal-gas particle box that responds to temperature. An animated dilution beaker. A pH spectrum you scrub with your thumb.

ChemKeys
Type chemistry
anywhere.
A system-wide keyboard that types proper formulas in any app — Messages, Notes, Mail. Subscripts, superscripts, charges, and reaction arrows, rendered correctly.
- Proper subscripts & superscripts — H₂O, SO₄²⁻, Fe³⁺
- Reaction arrows — 2H₂ + O₂ → 2H₂O
- Fully offline. No full access required.
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
1234 H₂O ²⁻ → ⌫
ChemKeys never requests full access: no network, no logging, nothing leaves the keyboard.
Built private, by design
Drawn dark for a reason.
Private for a reason.
Nothing leaves your device
All chemistry runs on-device. No account, no tracking, no network calls. The ChemKit engine is native Swift — your formulas, molecules, and history never touch a server.

Standing on shoulders
Every value is traceable to its source. Chemistry Explorer is a specimen cabinet — the specimens come from the open scientific record.
