Spell it once.
Be heard the first time.
Alpha Academy trains the one skill nobody teaches you: reading a code out loud so the other end gets it right. Booking references, email addresses, passport series, tracking numbers — letter by letter, in order, without being asked to repeat.
Spelled with an f so it survives every accent — never “Alpha” on the radio.
You are on the phone. One hand. Half a second.
Every other trainer is a study screen you read sitting down. The real moment is mid-call — the agent is waiting, you are three letters into a confirmation code and “S as in… Sierra?” is already too slow. Alpha Academy is built backwards from that moment: the chart is a primary surface, not a cheat sheet, and the drills use real strings instead of isolated letters.
Four moves from “A as in… apple?” to fluent.
Learn the plate
Each letter arrives on a light card: the glyph, the code word, a respelled pronunciation key and one line on why the word is what it is. Tap to hear it spoken.
Drill both directions
Letter to word and word back to letter. Each symbol carries its own mastery level, and the app schedules what you are about to forget instead of what you already know.
Read a real string
Encode a booking reference or an email address in order, or listen to one being spelled and write down what you heard. This is the exercise the rest of the app exists to feed.
Keep it warm
A Daily Drill built from your weak letters plus one string, and an optional reminder at a time you choose. Two minutes a day holds the whole chart.
Six ways in, one skill out.
Cards with audio
The plate, the pronunciation key and the mnemonic. Spoken on tap, at a speed you set.
See a letter, call the word
The direction you need when you are the one spelling.
Hear a word, write the letter
The direction you need when someone is spelling to you.
Spell it out, in order
A real reference from one of six scenario sets. Order counts — one letter out of place and the code is wrong.
Listen, then write it down
The hardest mode, and the one that transfers. Replay costs you.
Sixty seconds. Build a combo.
The only place a timer belongs. A run of right answers multiplies what each one is worth.
The strings you actually read out loud.
Encode and Decode draw from six sets, each with its own shapes and its own difficulty. You are never spelling nonsense.
Flight Numbers
Airline code plus number, as read at the gate.
Hotel Bookings
Confirmation references from booking systems.
Email Addresses
Where mis-hearing one letter costs the whole message.
Serial Numbers
Device and warranty codes read to a support agent.
Passport & Documents
Document series and numbers, letter by letter.
Tracking Codes
Parcel references — long, mixed, unforgiving.
Switch the set, keep your progress.
NATO / ICAO
The international aviation and maritime standard. Alfa through Zulu, plus the digits.
Able Baker
The WWII Allied military and aviation set. Four of its words survived into the modern chart.
Law Enforcement
The set used by US police and dispatch, where Adam and Boy replace Alfa and Bravo.
Always one tap away.
A full reference table you can reach mid-call — every symbol, its code word and how to say it. Searchable, and it never hides behind a session.
| Sym | Word | Say it |
|---|---|---|
| B | Bravo | BRAH-VOH |
| J | Juliett | JEW-LEE-ETT |
| L | Lima | LEE-MAH |
| M | Mike | MIKE |
Mastery per symbol, not one blunt score.
Every letter and digit carries its own level from 0 to 5. Answer it right and it moves up and gets scheduled further out; miss it and it comes back tomorrow. The chart fills in as you go.
Cadet, Operator, Instructor, Wing Commander — rank is information, never a lock. Nothing in the app is gated.
Your callsign
Your initials, spelled properly. Yours from the first launch.

Plays offline
The whole trainer works with no connection.
No account. No ads. No paywall.
You do not sign in. Your progress, profile and settings live on your iPhone, and deleting the app deletes them. The trainer itself needs no connection at all — we use an analytics service to measure installs and an optional push notification, both described in plain language on the privacy page.
