WP 34s vs Clover

WP 34s is the most powerful and complete implementation of a classic RPN scientific calculator. Now available on iOS too (see the support site for other emulators and for the real stuff). The function set of the WP 34S is based on the most powerful programmable RPN calculators built so far and we expanded the set, incorporating programmer functions (base 2, 8 & 16), a fraction mode, probability distributions, a stopwatch... We also included numerous additional useful functions for mathematics, statistics, physics, engineering, programming, I/O, etc., such as: + Euler’s Beta and Riemann’s Zeta functions, Bernoulli and Fibonacci numbers, Lambert’s W, the error function, and the Chebyshev, Hermite, Laguerre, and Legendre orthogonal polynomials (no more need to carry heavy printed tables), + many statistical distributions and their inverses: Poisson, Binomial, Geometric, Cauchy-Lorentz, Exponential, Logistic, Weibull, Lognormal, and Gaussian, + programmable sums and products, first and second derivatives, solving quadratic equations for real and complex roots, + testing for primality, + integer computing in fifteen bases from binary to hexadecimal, + extended date and time operations and a stopwatch3 based on a real-time clock, + financial operations such as mean rate of return and margin calculations, + 88 conversions, mainly from old Imperial to universal SI units and vice versa, + 50 fundamental physical constants as accurate as used today by national standards institutes such as NIST or PTB, plus a selection of important constants from mathematics, astronomy, and surveying, + Greek and extended Latin letters covering the languages of almost half of the world’s population (upper and lower case in two font sizes), plus mathematical symbols.

Clover is a third-party iOS client for TriliumNext Notes, designed reading-first: bring the knowledge base on your self-hosted server to your phone — readable offline, fully searchable. All core features are free. Clover Pro (one-time purchase or subscription): multiple servers, unlimited AI chats, alternate icons, home and lock screen widgets (today's journal, continue reading, quick capture), and Spotlight search. No ads. No server yet? Start with the built-in Local Vault and upload everything with one tap once you connect a Trilium server. Reading • Native typography with adjustable paper colour, font and size • Continuous multi-chapter reading for book notes, progress remembered • Images, PDF, Office documents, code highlighting, Mermaid, math • Full-text search that works for any language, including CJK Writing • Rich-text editor fully compatible with desktop Trilium • Journal: one note per day, capture fast; voice-to-text input • Share extension: save web pages, text and images from any app • Every write is queued first — nothing is lost offline, conflicts never overwrite Sync & security • Same login session as the Trilium web UI, with TOTP, SSO and Cloudflare Access • Incremental sync + live updates (foreground WebSocket), low-power and Wi-Fi-only policies • Face ID lock; protected notes unlock separately and never touch the disk • AI chat is powered by your own server — Clover stores no API keys Multiple accounts / servers, three-column iPad layout, localised in English, 简体中文, 繁體中文 and 日本語. Clover is an independent third-party client, not affiliated with the TriliumNext project. Syncing requires a TriliumNext server (0.99+); local-only use works without one.
