## CALC 1 Financial Calculator Reviews in United States

### *---- "Asking for review"
Just bought this app and you’re asking for a review? I find this unacceptable.
-- muurish, 2024-01-07

### ***** "I'm an old RPN guy"
I love this app. It works just like my old HP calculator.
-- FrankRuss, 2023-03-12

### *---- "Non stop pestering for a review"
I’ll be switching to a calculator that leaves me alone.
-- An unsatistied user, 2023-02-11

### *---- "Seems great, but asked for a rating 3 seconds after buying"
If I wanted to be slowed down by popups I'd use a calculator with ads. I've owned this app for all of 3 seconds and it's asking for a review, so here's my review so far.
-- pop-uph8trr, 2022-02-08

### ***** "Perfect for teaching my finance students"
I teach an upper lever finance class at a local university.  The Finance department requires that the students use TI BAs, so I use that primarily for in class examples. 
When I prepared for class and write my exams, I always work the examples on CALC 1 to verify my answers.  I love how I can export the history details to Notes.
And I also have the inputs for the TVM calculations recorded (N, I/YR, PV, PMT, FV, PYR, CYR and BEG/END) so I can double check all my inputs and answers. Just having the values shown right on the keys prevented a lot of miscalculations.  I like that this app also has a 12C that I am very familiar with having taken the CFA. I’d give it an A!
-- babygirlsteph, 2019-12-17

### ***** "Outstanding"
I usually use an HP 12CP but this has replaced that long standing relationship. Seeing the value on the keys is worth the price of admission. I am amazed by the scope of this app. HP should hire the developer to design their next product.
-- Imhotep VII, 2018-10-22
