Calculate phyllotaxis angles in botanical spirals. Measure divergence patterns, count contact pairs, and explore the mathematical architecture hidden inside seed heads.
All packages include core measurement tools. Advanced features require Android 7.0+. No subscription fees.
Plinks100 transforms botanical photography into precise mathematical models. Point your camera at any seed head – sunflower disc, pine cone, or daisy center – and the app overlays a parametric lattice grid. The software calculates divergence angles by analyzing the geometric relationship between adjacent primordia positions.
The bench mode generates synthetic seed heads from pure mathematics. Input any divergence angle between zero and 180 degrees, and watch as the algorithm builds a spiral pattern in real-time. Each simulated floret follows the cylindrical lattice formula, with plastochrone ratio determining radial spacing.
Survey mode bridges theory and reality. Mark visible spiral arms on photographed specimens, and the app computes the Fibonacci pair most likely responsible for the pattern. The lattice fit percentage reveals how closely natural growth follows ideal mathematical predictions.
Measure the golden angle with three-decimal accuracy. Adjust theoretical models from 95° to 145° and observe how contact pair identities shift as parastichy slopes reorganize.
Automatically detect visible spiral families in photographed specimens. The algorithm counts intersecting parastichy lines and suggests the most probable Fibonacci number pair.
Visualize the seed head as if cut and flattened. The wave pattern display reveals how spirals become diagonal lines when cylindrical geometry transforms to planar coordinates.
Compare real flower photographs against ideal mathematical predictions. Percentage scores indicate how perfectly nature followed the theoretical spiral arrangement formula.
Track the growth rate multiplier between successive floret positions. Watch this dimensionless value respond to divergence angle changes in bench mode simulations.
Tap to place counting dots along spiral arms in survey mode. The app links your manual counts to calculated divergence values and verifies pattern consistency.
