Also it complicated to use. Missing intuitive icons and menus. There is good help available within the app but occasional users will be required to run through how to use the app often to get the most out of it. Dev team, please fix the Apple Watch functionality! ### 3/5 — Good App, but.. *2015-04-04* Needs improvement in conversions. Not intuitive and clumsy. ### 3/5 — A little disappointed *2015-03-16* Calculator works ok, but the converter has some resolution inaccuracies. ### 3/5 — Good -- could use improvement *2015-02-22* Easy to use and attractive. Paid for premium mostly to support developers, since I liked the free version; but, I was sadly disappointed in the conversion feature since the conversions are all useless to me, who works in the medical field. ### 4/5 — Great *2015-04-09* Great app ### 4/5 — Very good but... *2015-03-10* There is a glitch that whenever I use the search for advanced functions, after I type a character, the keyboard glitches and closes. This is problematic and irritating since I have to type one letter at a time and it takes longer. Another bug I found is that whenever I put the phone into portrait mode, whenever I use the timer, half of the bottom buttons seems to show; however, the other half is off screen. Other than the problems mentioned, it's pretty good. I haven't run into any other problems...yet. ### 5/5 — Great calculator app *2022-12-22* seller still updating app. ### 5/5 — BEST Calculator App! *2016-06-25* That's all I can really say. I had been through several and none of them impressed me, but once I realized how this one works I love it! You should definitely download this app. It's all you'll ever need a calculator. It's killing me that more people haven't tried it out! Forget Texas Instruments!! Lol 🙃 ### 5/5 — Really cool features *2016-06-10* I don't write many reviews and I'll be short. This calculator has a ton of time saving features. The smart parentheses and smart tip calculator was an awesome idea. The new tutorial explains how to use the features well and are key to using all the features. ## Most praised reviews (7 highest-rated) ### 5/5 — Doesn't get any better than this *2016-02-04* I just spent the last week, looking at and trying many different calculators, even paying $10 bucks for one of them and none of them are as good or are as complete as this one. The interface has a small learning curve but with it comes amazing flexibility and powerful features. I don't usually write reviews but this one is well worth it! ### 5/5 — Great! *2015-03-20* Love the layout, ease of getting the additional functions and overall use ability of the app ### 5/5 — Kind of cool *2015-03-18* Except every single time I go too use the calculator I'm asked too leave a review little too often ### 5/5 — Good *2015-03-16* Does maths good ### 5/5 — Spectacular Calculator *2015-02-17* This has history and proper data conversions (both specs) and is also beautiful. All I could ask for! ### 5/5 — Keeps Getting Better & Better *2015-02-15* I really love this app so much. You can customize everything the way that you like it. I love the new button shapes and the new landscape mode, so cool! Thank you so much for updating this app and providing new awesome features. Five star app without a doubt!! ### 5/5 — Great app *2014-11-25* Very happy with it so far. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
