I first downloaded this calculator 29Dec2012 and have used it regularly. One might ask why would I give a one star review to something I’ve used for so long for free? The first 6 or 8 years or so there were absolutely no pop up ads. I think there may have been an ad banner at the bottom for a while but nothing crazy. It’s been a few years now that the ads have started increasing. I haven’t had a problem with that because they weren’t too bad. It started out with an ad that would pop up once every few times using it and would allow me to close it out pretty quick. It’s been getting more frequent and longer lasting ads. It’s now that every single time I go in to use it, one pops up and makes me watch a 15-30 second ad every single time. There are way too many options out there that it’s about time for me to delete this one and find a new one. Guaranteed I can find one that doesn’t have ads. Maybe I just go back to the one Apple provides. Been a good run for the past 12 years but I guess all good things do come to an end -- Plaid11, 2024-12-31 ### **--- "Too many long adds" In the last 6 months or so, too many long loud ads I’m powerless over. Meaning I can’t get rid of them. when I’m trying to do an important calculation. I have to wait until it goes through its loud until I can use again. -- DW1!, 2024-12-28 ### ***** "Muy buena esta aplicación" Super -- Puestaovando, 2024-11-04 ### ****- "Nice" Very nice layout and the price is right👍 -- Mathcansmd, 2024-10-08 ### ***-- "Works well but obnoxious ad placement" Works well but obnoxious ad placement -- Whiz one, 2024-09-15 ### *---- "I can only take pictures three times and it’s still not working" Kimaya hicks -- Kimaya hicks, 2024-09-11 ### ****- "Pretty good!" Layouts a bit confusing to me but other than that I love it! -- aizee🐬🦄🦢🕊❄️, 2024-07-16 ### *---- "Ruined by ads" It’s unbelievable how annoying and frequent the ads are. I’ve had this for a while but it just keeps getting worse. Smdh -- tigerJohnny123, 2024-06-28 ### ***** "Stuff" Good for dragon ball z power level -- alex know yyy, 2024-06-21 ### *---- "Gives the wrong answers" Doesn’t give right answers, terrible app. -- No username 101, 2024-04-29 ### *---- "Add to use basic calculator" You can’t work peacefully to do a basic operation without an add showing. Most of the time I use the web to avoid this. -- Hemh1, 2024-04-12 ### *---- "Non stop ads" this calculator is loaded with ads -- schoomy_booboo, 2024-04-01 ### *---- "Incessant and obtrusive ads" the ads are terrible! i can't use the app without full commercials playing. this is ridiculous! -- Les🌻, 2024-03-22 ### *---- "Why ???" why did you change the whole design ?? I use this app a lot everyday, I've had it for years And now it's just awful, everything is different I'm completely lost I regret doing the update ! I absolutely hate it It had everything we needed for maths I don't understand why you needed to change the whole design like that.. I'm going to have to find another calculator unfortunately... -- mfredhatkarlek, 2024-03-16 ### ****- "Great Calculator- too many ads" Title says it all. I’m too cheap to pay for ad-free if there is that option. -- lvo06, 2024-03-11 ### *---- "Terrible app" If I could give this zero starts I would. -- Because(of Sarah) mills, 2024-03-06 ### ****- "Trigonometry" The reverse trig doesn’t work for finding the angle -- dhdbfujdbdheeubxbx, 2024-02-28 ### ***** "To All" Me an mo and a iPhone jail broken -- 👹👿😈🤡👺 jennifer l laflora, 2024-02-25 ### **--- "unexpected full screen video ads with sound" I was considering this as a free calculator with ads.
