It does everything! But… Why is my calculator asking to track me across other apps and websites? That’s it, I’m destroying everything I own with a network connection. ### 3/5 — Loading screen annoying *2026-01-04, version 2.9.5* I loved using this calculator app until the recent update that added a loading screen and full screen ad before I am able to use it. This makes the app hard to use quickly and made me look for alternatives. ### 3/5 — Ads *2025-12-06, version 2.9.4* I've been using this app for years, and the ads and boot time to go through the ads make it almost time to uninstall for my needs. I am quite disappointed. ### 4/5 — Please add history even after clearing *2025-12-06, version 2.9.4* I enjoy using the calculator for school and have paid for the full version. Please consider adding history when you press the up arrow even after clearing the data. ### 5/5 — Just what I needed *2025-11-08, version 2.2.2* Very similar to the Texas Instrument Ti 30 XS. Well worth the price of $4.99 ### 5/5 — It’s GREAT! *2025-10-25, version 2.2.2* Just like the real thing, and I have two Ti-84 calculators. I’m only giving ‘5’ stars because I do believe it could use some polishing up to ‘appear’ like the real thing, and I do believe that the creators of this app might be surprised at how many more apps they would ‘sell’. I always ‘purchase’ to get rid of ads, which are totally annoying. You would sell FAR more if you gave your buttons more ‘depth’, with dark tiny spacing to define the button away from its frame; the way it is, currently, is way too duo-dimensional. Add more depth and shadowing to where the cosmetics are more realistic and I would wager that your sales would increase to where people would pay for your product more than just wanting the ‘free’ version. Regardless, this is an excellent app - I purchased the ‘Lifetime’ upgrade! ### 5/5 — Ein Rechner ohne Schnörkel *2025-09-23* Es ist noch viel zu früh und ich bin überhaupt nicht kompetent. Meine Leidenschaft ist das sammeln von Taschenrechnern. Echt , die die man in die Hand nehmen kann. Auf meinem IPhone habe ich diese hier zu meinem ständigen Begleiter gewählt. Ich glaube, es ist die richtige Wahl. Danke an das Team. Ich würde gerne spenden . Liebe Grüße, ein alter Fan ### 5/5 — Great app that simulates a ti84 *2025-09-22, version 2.2.2* Amazing app!!! ### 3/5 — 😅🤣💦 *2025-09-21* Complete nonsense! Why would you need a subscription for a calculator?! Next thing you know, we'll have to pay a thousand dollars a year for a flashlight switch. Maybe soon we'll have to pay monthly subscriptions for underwear and socks too. ### 5/5 — UI *2025-09-08, version 2.2.2* GUI look and feel is awesome; overall functionality is what it is supposed to be; I bought the life-time purchase’s option and I recommend it! ### 5/5 — Amazing *2025-07-22, version 2.2.2* Calculator has every function you could possibly need at an amazingly low price.

Die Kombination aus Funktionsumfang, Geschwindigkeit und durchdachter Benutzeroberfläche ist auf einem Niveau, das man sonst eher aus dem Ingenieursbereich kennt. Besonders hervorzuheben ist die Möglichkeit, komplexe Formeln sauber zu strukturieren und zuverlässig auszuwerten. Genau das, was man im beruflichen Einsatz braucht: keine Spielerei, sondern präzise Ergebnisse ohne Kompromisse. Die App wirkt bis ins Detail durchdacht – von der Eingabelogik bis zur Darstellung der Ergebnisse. Alles ist konsistent, stabil und effizient. Genau so muss ein Werkzeug funktionieren, auf das man sich verlassen will. ### 5/5 — Best Ti 84 calculator *2026-03-20* Excellence in design, with all the functions.
