The RLM-BA2 application is a general purpose calculator with a special focus in finance and business. It is inspired by the Texas Instrument BAII+Professional calculator, but specially designed to bring up the most of your iOS devices. The RLM-BA2 has a extensive Menu System: >Finance Worksheets: •Account Balance: Calculates the Balance of cash transactions and interest applied at arbitrary dates. •Amortization: Loan Amortization Schedule for a single or several loan payments. •Bond Price & Yield: Calculates the Price, Yield and Effective Duration of a Bond. •Black-Scholes Options: Calculates the CALL, PUT and “Greeks” values of a Black-Scholes European option. •Depreciation: Calculates depreciation with SL, SOYD, DB or MACRS methods and conventions. •Time Value of Money: Calculates compound Interest problems. >Business Worksheets: •Bill-Tip-Split: Calculates the sharing of a Bill with Tip. •Break-Even: Analyze the following relation: Profit = (Price - Var.Cost) • Units - Fix.Cost •Currency Exchange with on-line rates. •Percents & Margins: Calculates %Change, %Total and Business margins. >Cash Flows Worksheets: •Equal Periods: Calculations with Cash Flows occurring at regular time intervals. •Unequal Periods: Calculations with Cash Flows occurring at arbitrary dates. >Statistics Worksheets: •One-Variable Statistics: Calculations for one variable data samples. •Two-Variable Statistics: Calculations for two variables data samples. •Probability: Combinations, permutations and Normal, Exponential, t-Student and Weibull probability distributions. >Scientific Worksheets: •Angles & Polar: Convert angles and coordinates. •Logarithm functions with common or arbitrary base. •Number Alteration functions •Trigonometric & Hyperbolic functions. >Conversion Worksheets: •Angles & Polar: Convert angles between DEG,RAD,GRAD,DMS or Slope % and Polar-Rectangular coordinates. •Currencies: world currencies conversions with manual input or on-line current rates. •Interest Rates: Nominal and effective interest conversion. •Units: Physical units conversions. >General Worksheets: •Date: Calculates days between dates with Actual, 360 or 365 days calendars. •Time: Calculates time intervals between different times. •Solver: Calculates arbitrary equations entered as text expression to solve any of the variables knowing the others. •Storage Registers: Store and perform operations directly over the calculators storage registers. •Memory Content: Clear, Back-Up or Restore part or all of the Calculator's memory. •General Settings: Customize many aspects of the calculator including formats & feedbacks. •Help Documents: Description and examples of all the calculator worksheets and features. >Editors Worksheets: To create or edit data •(Date,Trx) List: Transactions and the dates they occurs for the "Account Balance Worksheet". •(Date.CF) List: Cash flows and the dates they occurs for the "Unequal Periods Cash Flows Worksheet". •(X,N) List: Cash flows and repetitions for the "Equal Periods Cash Flows Worksheet". •(X,Y) List: X and Y data samples for the Statistics worksheets. •Solver Equation: Algebraic expression for use in the "Solver" worksheet. •Units Database: Customize the "Units" worksheet. System requirements: iOS 15.0 or above. 30 days Free-Trial. In-App-Purchase: One-Payment for life.

Here come the general/special purpose equation/function calculator! Students, scientists, accountants, merchants, anyone can easily use it for a instant result. Usage: -equation string, e.g. 1+2x3-4÷5.0-.2+1+2^5 = 39 -VAT % calculation, e.g. 7 % x 56000 = 3,920 -Auto Floating point operation, e.g. 11÷2 = 5.5 11.0÷2 = 5.5 11÷2.0 = 5.5 -compound operators and precedence +, -, x, ÷, ^, e.g. 1+2x3÷4-5 = -2.5 1+2x3÷4.0-5 = -2.5 2^10 = 1024 -use parenthesis ( ) as highest operator precedence. e.g. (3+6)x2-3÷2 = 16.5 -always use parenthesis to prevent ambiguity, e.g. √9+2 means √11, to get √9 plus 2, equation must be (√9)+2, result: (√9)+2 = 5 -perform x^y, e.g.2^16 = 65,536 -perform square root, e.g. tap √ , tap 6 2 5, tap = , result: √625 = 25 -compute %, e.g. to compute 5% of 300. Tap 5, tap %, tap x, tap 3 0 0, tap =, result: 0.05x300 = 15 -compute logarithm base 10, e.g. to compute log1000, Tap log, tap 1 000, tap =, result: log1000 = 3 -equation log100+10 means log110, to compute log100 plus 10, equation must be (log100)+10, result: (log100)+10 = 12 -compute natural logarithm base e, e.g. ln2, Tap ln, tap 2, tap =, result: ln2 = 0.693147 -compute factorial, e.g. 5!, Tap 5, tap !, result: 5! = 120 -compute inverse of x or 1/x, e.g. 1/25, Tap 25, tap 1/x, result: 1/25 = 0.04 -compute area of a circle with radius 5, e.g. Tap 2, tap x, tap Pi, tap x, tap 5, tap =, result: 2xPix5 = 31.4159 -Continuous computation, e.g. to compute 7.5% of 800 then add by 1000. Tap 7.5, tap %, tap x, tap 800, tap +, tap 1 000, tap =, result: 0.075x800+1000 = 1060 -Tap share button to share the result of the computation to other apps. -Tap M+ to add result in memory, -Tap M- to subtract result in memory, -Tap MR to recall result from memory. -Tap MC to clear result from memory. -Tap hist button to to view and select the previous calculation history. -long press equation or result label to copy/paste equation and/or result to/from other app, e.g. 17.0+2x3-4x5÷6+7-8x9÷5+6x7-5 = 49.266667 -Tap speaker On/Off button to toggle button click sound. Note: -Operators (, ), +, -, x, ÷, and ^ can combine into a long equation string. e.g. 17+2x3^2-4x5÷6.0+(7-8)x9÷5.0+6x7-5 = 66.866667 -Computation follows operator precedence, e.g. 1+2x3-2^3+1 = 0 2x(3+4)÷3.0+5 = 9.666667 -Operators !, % and 1/x can only be used in a single operation or first operator in mixed operation. e.g. 5!, 6%, but not 2 + 5!, not 20 + 5%. -but can use as first operator. e.g. 5! + 2, or 5% + 20. - Mod operator can not be mixed with other operators, to compute 34 mod 5. Tap 3, Tap 4, tap Mod, tap 5, tap =, result: 34 Mod 5 = 4 - nCr operator can not be mixed with other operators, to compute 5 nCr 2. tap 5, tap nCr, tap 2, tap =, result: 5 nCr 2 = 10, note that, n>=r>=0. Invalid equation: 2√9 must change to 2x√9 2log100 must change to 2xlog100 2Pi5 must change to 2xPix5 In equation, multiplication must always use x operator.

Verdict
The clearest difference is in-app purchases: Calculator 2024 at none against RLM's 1. Calculator 2024 also leads on update cadence (fortnightly vs every 2 months) and iOS requirement (11.0 vs 15.0). RLM's advantage is ads (none vs shown). On price and device support there is nothing between them.
