"The graphing option is extremely useful"

Over 5,000 downloads worldwide!

Apptuary is THE app to have if you're an Actuarial student or a qualified Actuary - PARTICULARLY if you're tired of looking up values in tables of figures.

Apptuary is the ONLY actuarial app to feature downloadable Life Tables, and makes life-contingent annuity, compound-interest, option and statistical calculations fast and easy.

Apptuary can calculate:

• Values for life contingent annuities and assurances for single and joint lives, for any combination of interest rate and term.

• The values of all of the first and second order Greeks, using the Black-Scholes model of option prices.

• Values for annuities-certain for:
- any interest rate
- any number of payment years (including infinite)
- any number of payments per year (including continuous)
- any deferral period.

• Cumulative probabilities for a number of discrete and continuous statistical distributions, as well as values for the inverses of those cumulative distributions:
- Binomial
- Bernoulli
- Poisson
- Negative Binomial (Type I)
- Negative Binomial (Type II)
- Geometric
- Uniform (Discrete version)
- Standard Normal
- Normal (Gaussian)
- Exponential
- Gamma
- Chi-square
- Uniform (Continuous version)
- Lognormal
- Pareto (Two-parameter version)
- Weibull
- Burr

• The means and variances for the above distributions PLUS the following:
- Beta
- Pareto (Three parameter version)

## Key features

- Downloadable life tables
- Life contingent annuity and assurance calculations
- Option pricing (Black-Scholes model)
- Annuities-certain calculations
- Cumulative probabilities for statistical distributions
- Inverse cumulative distribution values

### 5/5 — Great date night activity

*2023-03-11*

This typically confirms I am normal to my date! Unfortunately there aren’t enough functions to make it through two dates and I think that’s the main reason girls don’t call me back after the first date :(

### 5/5 — Great Resource

*2021-03-22*

This app is a real life saver. It shows you tons of of different distributions and let’s you plug in variables to get different results like the expected value, variance, probability, or plot. It is very useful for someone who knows how to do the computations but just needs a way to get them fast and easy.

### 1/5 — Rubbish

*2018-03-06, version 3.08*

Forces you to write a review.

### 5/5 — Good stuff

*2015-11-25, version 3.04*

Created by potentially the most influential Actuary in Australian history. A pity he's a kiwi.

### 4/5 — Useful

*2015-03-17, version 3.02*

Quicker than using the tables.

Just a note that the values being shown for increasing annuities in advance is the value for those in arrears. Can this be fixed?

### 5/5 — Awesome Little Tool

*2013-04-09*

This is a great no-nonsense app for checking my work. Very easy. I wish I could use it on exams!

### 4/5 — Very useful

*2012-03-26, version 2.02*

As an actuarial student, I find this app faster and more extensive than actuarial tables. Great app.

### 5/5 — A must have for an actuarial student it can be used to even study while you commute

*2012-02-22, version 2.01*

.

### 5/5 — Very useful!

*2012-01-29*

Great app for most of the distributions actuaries use. Great for studying when you just need a quick answer. The graphing option is extremely useful for a visual representation of whatever you're trying to accomplish.  A must-have for an actuary of any level.

### 5/5 — Wish I had this for exam C

*2012-01-17*

It looks fairly complete. Able to solve and show formulas for all of the formulas you may see through exam C (that I can remember).

Nice graphical representation as well. Sometimes nice to see to better understand what the distribution looks like and how it changes with the parameters!
