Overview

Fasty Letters is a letter recognition game for ages 4 to 7. It does not march through the alphabet in order. It watches which of the 52 uppercase and lowercase letters a child misses and brings the least-mastered one back every third question. Letter Match asks the child to pair capital and lowercase forms; the app says each letter name aloud, capital A and a. Letter Recognition says a letter name, such as uppercase B, and the child taps it from four cards. Cards are large, audio plays on every prompt, and haptics work even when the device is muted. Parents get a mastery grid with four tiers, Not Started, Beginner, Practicing, and Mastered, for up to four profiles on one device. The app teaches letter names and shapes, not letter sounds, tracing, or blending. No ads, no in-app purchases, no social features, and gameplay works offline. Free on iPhone and iPad, iOS 18.6 or later.

Key features

  • Weak letters come back

    Every third question is the child's least-mastered letter, tracked separately for all 52 uppercase and lowercase forms.

  • Letter Match and Letter Recognition

    Pair capital and lowercase letters, or hear a letter name and tap it from four cards. Every prompt is spoken.

  • A mastery grid you can read

    An A to Z grid in four tiers, Not Started, Beginner, Practicing, and Mastered, with per-letter accuracy for each profile.

  • Built for ages 4–7

    Large cards, haptics, audio that plays on a muted device, and monster celebrations so a pre-reader can play alone.

  • Safe by design

    No ads, no in-app purchases, no social features, no account. Up to four profiles, with data staying on the device.

Benefits

The letters that slip get another turn, instead of a random pass through the alphabet.

  • Practice lands on the letters a child misses

    Every third question is the least-mastered letter. A child who already knows capital B does not spend the round proving it.

  • A pre-reader can play alone

    Every prompt is spoken, cards are large, and haptics confirm a tap even on a muted device. Monster celebrations close each round.

  • You can see which of the 52 letters are solid

    Uppercase and lowercase are tracked separately on an A to Z grid with four tiers, so the next session starts where the gaps are.

Use cases

Practical ways people use Fasty Letters day to day.

    A quick look at which letters a child still misses

    Up to four profiles on one shared iPad, each with its own mastery grid and per-letter accuracy.

  • Caregivers

    Gameplay needs no connection and nothing in the round sells the next thing.

Frequently asked questions

Ages 4 to 7, letter names versus letter sounds, the two modes, and what stays on the device.

What ages is Fasty Letters for?

Ages 4 to 7, the pre-K and kindergarten window. Large cards, spoken prompts, and haptics are built so a child who cannot read yet can still play a round alone. The App Store rating is 4+.

Does Fasty Letters teach letter sounds?

No. The audio is letter names: capital A, a, uppercase B. Fasty Letters teaches recognizing and naming the 52 uppercase and lowercase letters. It does not teach phonemes, tracing, handwriting, or blending. The letter names and sounds guide explains the difference.

How does the adaptive practice work?

The app tracks each of the 52 letter-case combinations separately. Every third question is the child's least-mastered letter, so weak letters come back often and known letters do not fill the round.

What is the difference between Letter Match and Letter Recognition?

Letter Match shows six cards, three pairs, and the child matches each capital letter to its lowercase form while the app says the names. Letter Recognition says a letter name, such as uppercase B, and the child taps it from four cards. Each mode has its own mastery dashboard.

Are there ads or in-app purchases?

No. Fasty Letters is free with no ads, no in-app purchases, no social features, and no account. Up to four profiles stay on the device. The App Store privacy label is Data Not Collected.

Which devices does it run on?

iPhone and iPad on iOS or iPadOS 18.6 or later. There is no Android version and no browser version.
