Tenets vs Calc

Most planning tools optimise for output. Tenets starts with your values — and works backwards to what your year should actually look like. Tenets is a private, on-device life planning tool for people who want to live deliberately, not just productively. VALUES FIRST Before you plan a single goal, Tenets asks what your life stands for. Three reflective questions — with on-device Apple Intelligence to suggest values if you want the help — become the three to five principles everything else serves. Every domain you plan links back to a value, so your year is grounded in what matters, not just what's measurable. ANNUAL OKRS FOR YOUR LIFE Domains replace teams. Objectives stay ambitious. Key results stay honest. The framework that runs great organisations, applied to the one project that actually matters. A guided wizard proposes a full year structure in minutes — you decide what stays. A WEEKLY PULSE Ninety seconds. Energy level, a theme, values alignment, a short note — typed or dictated. The compound effect of staying honest with yourself, week by week. The dashboard tells you when a pulse is due; the widget keeps your progress on your desk. A MONTHLY REVIEW Rate each key result, then talk it through with the council — four on-device AI personas (the Auditor, the Scientist, the Witness, the Philosopher) that read your actual data and ask the questions a good coach would. Every review becomes a written record you can revisit. A LONG VIEW Time Machine shows year-over-year trends, monthly activity heatmaps, and key result history — the shape of your years, not just the last 30 days. IN SYNC, PRIVATELY Your plan follows you — Mac, iPhone, iPad — synced through your own private iCloud. No account with us, no server of ours, no analytics. All AI runs on-device with Apple Intelligence (macOS 26 / iOS 26; every feature has a full manual path without it). Works fully offline without iCloud, and your data is exportable as plain JSON at any time. BUILT FOR THE KEYBOARD ⌘K jumps to any domain, objective, or key result. ⌘1–⌘5 switch views. ⌘N logs a pulse, ⌘⇧R starts a review, ⌘Z undoes. Deliberate planning at the speed of thought. Now on Mac, iPhone, and iPad.

Calc-U-59 is a TI-59, TI-58, and TI-58C emulator for iPhone, iPad, and Mac. It runs the original ROM, so every program, module, and quirk works exactly as it did on the real hardware — with virtual magnetic cards, a PC-100C printer, all fourteen Solid State Software modules, and a CPU-level debugger for anyone who wants to look under the hood. CYCLE-ACCURATE EMULATION The TMC0501 processor is emulated at the cycle level, reproducing the exact behaviour of the original hardware — including the TI-58C's constant memory, preserved across restarts. The Master Library ROM and many more modules are included. INTEGRATED DEBUGGER Inspect program memory, data registers, CPU state, and internal SCOM registers live as the machine runs. Step through instructions one at a time, or let the emulator run and freeze it at any point. You can even run your own assembly programs! Available on iPad (landscape) and Mac. PAPER TAPE PRINTER A functional recreation of the PC-100C thermal printer with dot-matrix font rendering. Trace exactly what programs print and why. Copy output as plain text or as a high-resolution bitmap. MAGNETIC CARD READER Load and save programs and data registers as card files, stored on your device and synced via iCloud. Bring old listings back to life and run them under the debugger. STATE FILES Load .ti59 and .ti58(c) state files to instantly configure the machine with a program, registers, and flags — ideal for sharing reproducible scenarios or revisiting known machine states. SOLID STATE MODULES Select a Solid State Module and run programs from there. Whether you're bringing an old program back to life, running the Master Library modules, or exploring how these machines actually worked under the hood, Calc-U-59 gives you a faithful TI-59 in your pocket.
