Pansophia is an offline STEM reference for engineers, scientists, and students — 25,400+ formulas, compounds, and reference tables across 18 disciplines including physics, chemistry, biology, mathematics, and every major field of engineering. No account. No ads. No tracking. No internet required. About a third of every discipline is free. WHY PANSOPHIA Every entry is curated, cross-referenced, and verified — not generated. When you need a decay constant, a beam capacity, or a CAS number, it has to be right, and it has to work without a signal. Built for the lab bench, the job site, and the exam desk. The kind of data you used to search for daily, or flip through a mountain of handbooks to find — now in one place. WHAT'S INSIDE - 3,000+ biological species with habitat, functions, structures, timeline - 1,200+ chemical compounds with properties, synthesis, hazards & CAS numbers - 700+ mechanical components — fasteners, bearings, hinges, latches, brackets, clamps, belts/chains, flanges, gears, couplings, pumps, pneumatics + hydraulics, etc - 500+ electronic components — transistors, op-amps, microcontrollers (Arduino/STM32/ESP32/RP2040), motors, sensors, LCDs, batteries, etc - 350+ chemistry lab reference entries — solvents, buffers (Tris/PBS/HEPES), catalysts (Pd, Grubbs, MacMillan), spectroscopy (NMR/IR/MS), HPLC/GC chromatography - 254 materials — alloys, polymers, ceramics, composites, AHSS, bulk metallic glasses, high-entropy alloys, fracture toughness & creep data - 231 astronomical objects — Messier catalog, notable stars, exoplanets, black holes - 280+ structural engineering tables — AISC W/HSS shapes & beam design, RC design, NDS wood design, foundations (spread/pile/mat/retaining), seismic design, soil classification, building codes, bridges - 80+ chemical engineering reference — distillation & absorption unit ops, TEMA heat exchangers, CSTR/PFR/PBR/fluidized reactors, ASME VIII pressure vessels, API 650/620 storage tanks, relief systems, ISA-5.1 P&ID symbols, NEC/ATEX hazardous areas, HAZOP/LOPA/SIL methodology - 220+ biomedical reference entries — FDA device classes, ASTM F-series implants, ISO 10993 biocompatibility, clinical trial phases, lab values (CBC/BMP/CMP/LFTs/ABG), vital signs by age, imaging (X-ray/CT/MRI/US/PET) - 280+ pharmacology drug classes — full WHO ATC coverage with mechanism, dosing, adverse effects, interactions - 111 nuclear isotopes with cross-sections and decay data - 72 named organic reactions with reagents, conditions & mechanisms - 61 algorithms with time/space complexity analysis - 56 statistical tests with assumptions, formulas & when to use each - 48 math identities — trig, integrals, Laplace & Fourier transform pairs 18 DISCIPLINES Physics, Chemistry, Biology, Mathematics, Computer Science, Artificial Intelligence, Statistics & Data Science, Electrical Engineering, Mechanical Engineering, Civil & Structural Engineering, Chemical Engineering, Biomedical Engineering, Industrial & Systems Engineering, Nuclear Engineering, Materials Science, Astronomy & Astrophysics, Earth & Environmental BUILT-IN TOOLS - Scientific Calculator — 52 built-in constants, trig/log/factorial, history - Unit Converter — 22 unit families including electrical & magnetic - Physical Constants — 163 constants with uncertainties, searchable & copyable - Quiz & Flashcards — SM-2 spaced repetition for coursework and exam prep CROSS-DISCIPLINE CONNECTIONS 27,500+ cross-references link related concepts across fields.

Verdict
The clearest difference is monetization model: Pansophia at free against AceNotes's freemium. Pansophia also leads on device support (4 vs 2). On price, rating, review sentiment and ratings volume there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Pansophia sells 10 one-off in-app purchases and AceNotes sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Pansophia against 5.0 for AceNotes. Both are backed by a comparable volume of ratings — 2 and 5 respectively. Written reviews split almost evenly too, at 100% and 100% positive.
Pansophia ships an update every 4 days, AceNotes weekly. The most recent releases landed on September 13, 2026 and July 8, 2026 respectively.
