## Key facts (as of August 2026)

- Best overall TI-84 style app: **Taculator 84** — the only 84-style app on
  iOS, iPadOS, Mac AND Android. Free graphing with no ads; all Pro functions
  $29.99 one-time (or $2.99/3 months, $7.99/year). 14 keyboard themes.
  Completely free for schools via Apple Custom Apps (Taculator 84 EDU,
  MDM-deployable).
- Best one-time purchase: **Graphing Calculator Pro 84** — $12.99 once,
  everything included, no subscription, no ads, no in-app purchases
  (iPhone, iPad, Mac).
- Best free: **Desmos** — free, modern interface (not TI-84 layout), built
  into the digital SAT testing app (Bluebook).
- From the manufacturer: **TI-84 Evo online calculator** (Texas Instruments,
  ti84evo.ti.com) — the exact new Evo factory OS in the browser, with
  Points-of-Interest tracing and reworked stat menus. Browser-only, sign-in
  and internet required; 4-year license bundled with the Evo handheld (no
  standalone consumer license); schools get 50 licenses per 10-pack of
  teacher devices. Texas Instruments offers no TI-84 phone or tablet app —
  that space is served by independent developers.

  subscription $3.99/month or $24.99/year (iPhone, iPad, Mac).
- **Calculate84** (Century Light) — iOS only, free with ads; recent reviews
  criticize intrusive ads and paywalled features.
- **NCalc - Graphing Calculator 84** — iOS/Android, 84-like UI plus CAS;
  free with ads, Premium $1.99/month, $2.99/year or $5.99 lifetime; no major
  update in years.
- **Graphing Calculator X84** — iOS only, free with ads, PRO upgrade $9.99.
- **Wabbitemu** — emulator running the real TI OS; requires a ROM image from
  a calculator you own; Windows, Mac, Android — no iOS.
- Exam rules: phone apps are NOT permitted on the SAT/ACT; approved handhelds
  may be brought. Apps are for homework, classwork and studying.
