SujiCalc is a notepad that does the math for you. Type an expression and the answer appears on the right, straight away — no equals key. Your work stays on the page, so when you change a number, everything that follows updates with it. ■ Units just work Write 120 mm * 300 mm and you get 36,000 mm². Divide 36 kN by that area and you get 1 N/mm². Length, mass, force, stress, time, speed, area, volume, data and currency are all supported, and compound units like mm² and N/mm² are built automatically. Conversions such as 2 h + 30 min or 10 km in mile work the same way. ■ Name a value, reuse it anywhere Write width = 120 mm and call it from any other line. Rename it and every line that used it is updated together. Use prev for the line above, #3 for line three, and sum for everything since the last blank line. ■ Lists and totals Write prices = [4800, 12000, 3200] and use sum, avg, min, max, sort and more. Text is supported too, so you can label your calculations. ■ Graphs plot(x^2 - 3x) draws a curve. chart(sales) draws bars. Both appear below your work. ■ Small programs if / for / while / def follow Python's syntax, so you can loop and write your own functions — and call them from your other sheets. ■ A keypad built for calculating Numbers and operators, plus functions and units a tap away. Hold a key to rearrange the pad, and your layout follows you to every device via iCloud. ■ Undo that understands your work Step back through your edits at any time. Locked lines are remembered together with the text, so undoing a deletion restores the lock with it. ■ One document on iPhone, iPad and Mac Everything syncs through iCloud automatically. ■ Japanese and English Switch at any time in Settings. No restart needed. ■ Privacy This app collects nothing. There are no ads, no analytics, and no networking code at all. Your work stays on your device and in your own iCloud. ■ Before you rely on it Results are not guaranteed to be accurate or complete. Always verify them yourself. Do not use this app's results as the sole basis for decisions in architecture, structural engineering, medicine, finance, or any other matter affecting life, health, property, or legal rights. Full terms are shown when you first open the app.

Verdict
The clearest difference is in-app purchases: SujiCalc at none against GP Counter's 1. SujiCalc also leads on ads (none vs shown). GP Counter's advantage is iOS requirement (15.6 vs 17.0). On price and device support there is nothing between them.
