Argus Mobile is a companion to Lucidea’s Argus Museum Collections Management System. Argus museum and gallery clients can use it to work remotely while roaming galleries or warehouses. Scan collection object, box, or location barcodes, then tap to set the new location for a single object, a single box, or a collection of objects or boxes. You can also indicate location type, such as “temporary” or “permanent” so you’ll always be up to date. Setup is simple. Just scan a QR code, then log into your Argus system using the same Login ID and password you use to access Argus with your web browser. Requirements: • Argus 4.3.5.51 or higher, with barcode and API features, on an SSL server. • The Argus barcode features configured. • The Argus API enabled. • Barcode labels using Code 39, Code 39 Mod 43, Code 128, or QR codes. • Any iPhone, iPod touch, iPad, iPad Air, iPad mini, or iPad Pro currently supported by Apple, with iOS 12 or later.

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.

Verdict
The clearest difference is update cadence: Calc at fortnightly against Argus Mobile's every 6 weeks. Argus Mobile's advantage is iOS requirement (12.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
