Spendjar vs Modbus 40001

Spendjar is a fast, private expense tracker built around one simple idea: your money is easier to understand when every expense has a category. Groceries, dining, transport, bills — give each one a monthly budget and always know where your money is going, with no account and no subscription. Log an expense in seconds: enter the amount, pick a category, and Spendjar keeps a running total for the month plus a progress bar for every category and one overall budget on the home screen. Tap any category to see its expenses and exactly how much of its budget is left. Everything stays on your device. There is no sign-in, no cloud sync, and no data ever leaves your phone — just a clean, one-screen way to track spending by category and stay on budget. Spendjar Pro is a one-time purchase — no subscription. It removes the 5-category limit, unlocks full month-by-month history so you can look back at past spending, and lets you export any month as a plain-text summary in one tap.

Modbus 40001 is a Modbus/TCP master & slave for testing and commissioning industrial equipment — PLCs, drives, meters, and controllers — from an iPhone or iPad. Enter a device's IP address and port, choose a function code, and continuously poll a block of coils or registers of any size. Values update live, changed cells flash as they move, and holding registers and coils can be written back with a tap. FEATURES:- • Function codes 01–04 — Coil Status, Input Status, Holding Register, Input Register • Any block size — set the start address and length, checked against the protocol limits for each function • Poll rates from 100 ms to 5 seconds • Value notations — unsigned and signed decimal, hex, binary, 32-bit long, Float32 and 64-bit double in both word orders • Character notations — ASCII in either byte order, plus a low-byte form, with a joined readout so device names and serial numbers read as text • Writes — tap a cell to send Preset Single Register (06) or Force Single Coil (05) • Multiple scan documents — save several register blocks per device and switch between them • Addressing toggle — 1-based (PLC style) or 0-based (raw protocol), so off-by-one confusion is a single tap away from being resolved • Traffic view — every frame in and out as bracketed hex, with capture and clear • Status strip — polls, valid responses, errors, success rate, latency, and last update time • Built-in demo device — try every screen without hardware on the bench • Designed for both orientations — iPad keeps a two-column layout, iPhone scrolls the whole page No accounts, no analytics, no advertising. Device addresses and scan settings are stored only on your device. Intended for general testing of the Modbus/TCP protocol. Not certified for safety-critical use.
