Read full description

Designed for apprentice and self-taught perfumers. As easy as using a pen and paper but allows you to make connections between raw materials and formulas which a traditional notebook can't provide. Keep your raw materials organised with collection of cards to store information. Keep track of basic information such as supplier, IFRA limits and cost per gram. Add dates for purchasing your stock and making dilutions to act as a reminder to when raw materials may have gone off. A table summarising concentration in formulas serves to quickly remind you which usage levels you found the most success with. Organise your formulas into custom categories and sketch out new ones with ease. Simply search your raw materials library and set a weight in grams up to 3 decimal places. Mark formula entries as too strong or weak. Change the dilution of a formula entry or swap out a raw material as you please. Formulair makes all of this quick and easy. Features: - A custom scaling engine helps you scale formulas up and down using a scaling factor, target weight or target concentration. - View a fragrance pyramid split into 5 levels of substantivity and a visual raw material category breakdown for each formula. - Keep track of different raw materials' dilutions and change dilutions in formulas using the existing solvent. - Includes a setting to scramble your raw material usage table, hiding sensitive formula information. - Your data is secured by apple in a private iCloud container. - Featuring a carefully designed colour palette, allowing you to assign colours to fully capture the essence your raw materials. - A rich interface supports light and dark mode. Even the raw materials colour palette adapts dynamically. - Raw material cards include a listing of every formula it's used in from strongest to weakest, showing any flags you set for too strong or weak. - Export formulas to pdf allowing you to print and share, markdown to open in note taking software, or tsv (tab-separated value) files, to load into spreadsheet software. Pricing: Formulair allows you to add up to 25 raw materials and up to 25 formulas for free. Once you try to go above this limit, you will be offered a one-time in-app-purchase to buy the full version, which allows you to create unlimited raw materials and formulas.

About

ForeVolt

Features
Read full description

ForeVolt is a physics-based battery degradation and lifetime modelling tool for engineers, researchers and advanced users. It simulates calendar ageing, cycling fatigue, lithium plating, power fade and usable energy loss to predict long-term State of Health under real operating conditions. Unlike simple cycle counters, ForeVolt models the underlying electrochemical stress mechanisms that drive capacity loss and resistance growth. Key features: • Long-term State of Health and End-of-Life projection • Knee-point detection for accelerated degradation regimes • Power capability and usable energy modelling • Temperature, depth-of-discharge, C-rate and storage condition inputs • Calendar vs cycling vs plating contribution breakdown • Sensitivity analysis to identify dominant ageing drivers • Interactive charts with zoom, probe and regime visualisation • PDF report export for sharing and documentation ForeVolt is designed for: • EV and battery engineers • Energy storage consultants • Researchers and students • Fleet and asset managers • Advanced enthusiasts who want realistic lifetime modelling All simulations are based on established degradation physics and Arrhenius-type stress acceleration, not simple rule-of-thumb curves. A free demo allows exploration of the model. ForeVolt Pro unlocks full interaction, presets, advanced analysis and report export. Subscription Information ForeVolt Pro is an auto-renewable subscription. • Title: ForeVolt Pro • Duration: Monthly / Annual (as listed) • Price: As shown in the App Store • Auto-renews unless cancelled 24 hours before period end.
