HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (6.4 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Price and subscription14%

7 of the 1 and 2 star reviews.

★★★★★ The free version ads have apparent scams. One pop up window from the app telling me there's $187 Apple account authorization on holding waiting for my approval. Stay away from the app!
★★★★★ I paid for the ad free version and I am still seeing ads. Developer doesn't respond.
★★★★★ I bought the ad free version TWICE I think. Now all of a sudden ads pop up all over the place. Nothing seems to work and it is asking me to buy it again even though I already did last year. Stay away!
Wrong or poor results10%

5 of the 1 and 2 star reviews.

★★★★★ Does not calculate properly anymore. I have the actual calculator and does not match up with app version results. :(
★★★★★ I used this app to calculate mortgage payments and the amount comes out wrong.
★★★★★ This makes the app useless.
Worse after an update6%

★★★★★ Update: Turns out I have the paid version however had accidentally selected the ad version.
★★★★★ Last update plays an add with sound when I start it.
★★★★★ Have used this app for YEARS but am deleting it tonight after updating it to the latest version.
Bugs, things not working4%

2 of the 1 and 2 star reviews.

★★★★★ It stopped working after the iOS upgrade.
★★★★★ I get the migration notice on my copy of 16i on both phone and iPad. Installing this app, shows no upgrade path info even after restoring purchases. Obviously not reliable, judging from other reviews here. Also am…
Login and account problems4%

2 of the 1 and 2 star reviews.

★★★★★ One pop up window from the app telling me there's $187 Apple account authorization on holding waiting for my approval.
★★★★★ Why is your app the only one that consistently has a window popping up asking me to input my Apple ID password?
Lost data, sync, backup4%

2 of the 1 and 2 star reviews.

★★★★★ Shouldn't have deleted the old one before finding out this was a financial calculator - not an 11c.
Missing features4%

2 of the 1 and 2 star reviews.

★★★★★ There is no way to dismiss this!
★★★★★ There's no option for upgrade with no ads.

Worth the money22%

12 of the 4 and 5 star reviews.

★★★★★ For the traditional 12c users, definitely worth the few bucks to go ad free.
★★★★★ This is an excellent HP12C emulator anf is free with ads.
★★★★★ The free version is incredibly annoying with all the ads.
Accurate, great results13%

7 of the 4 and 5 star reviews.

★★★★★ This is an excellent HP12C emulator anf is free with ads. The ads don't bother me and saves $10+ from buying the actual HP app.
★★★★★ I set it back to zero and everything works perfectly again.
★★★★★ I have not done a thorough test on accuracy but it appears to be accurate.
Fast7%

4 of the 4 and 5 star reviews.

★★★★★ Very fast, and true to HP12c.
★★★★★ The only minor concern is on the last one: it replaces the Bond functions with these other ones, but the quick reference card (simulating the back of the calculator) still shows Bond related functions there.
★★★★★ Very handy for doing quick calculations of loan charges.
Useful, it helps4%

2 of the 4 and 5 star reviews.

★★★★★ I have been using this app for years and its beyond helpful.
★★★★★ A really useful app that one doesn't have to learn.

★★★★★Apr 26, 2026
Ads a’plenty

Now featuring full screen ads. Why bother with calculator nonsense when you can bask in full bore unbridled advertising hypersaturation!

★★★★★Apr 4, 2026
iPhone rendering change?

I’ve enjoyed this app for several years. Recently I’ve noticed an appearance change on my iPhone. The display and keyboard seems stretched in a vertical direction. Was a change made?

★★★★★Feb 3, 2026
ADS!

I assumed the premium version would be ad free. Not so. Still have very annoying ads.

★★★★★Jan 27, 2026
Use the paid version daily

I still have a working original HP-16C on my desk. But when I’m not at my desk, I use this app and have for many years. Looks and works just like the real thing. No ads in the paid version and I love the portrait and landscape modes. Would like a Paste feature however.

★★★★★Jan 18, 2026
Premium version worth

For the traditional 12c users, definitely worth the few bucks to go ad free. Having an rpn calculator on your phone is worth it vs carrying a 12c around. Who really wants to carry one nowadays give the developer credit for making life a little easier

Ads

Paid for the ad free version and still get ads
