Read full description

Build your own keyboard! Touchscreen keyboards don't need to be one-size-fits-all, so let's change that! With Keybuild, you choose the layout, the keys, everything. Keys can be set up to type whatever you want! Letters, greek letters (ɑ, β, ɣ), maths symbols (π, ∫, ∑), arrows (↑→↓←), or even your favourite emoji can be added and organised depending on your needs. Create multiple ‘panes’, each containing keys arranged using a stack-based layout, and switch between them with either an automatic menu, or direct links. Add a small number row to your Qwerty keyboard, or have a try using Azerty or Colemak layouts. Build a keyboard that can keep up with your maths-heavy university course, or specialist profession. Or just make a dashboard for your favourite emoji. Or do all that and more, it's up to you! This app does its best to supports VoiceOver, and accessibility APIs. Technical note: This app is 99% SwiftUI, which is as close as you can get while we wait for the ‘SwiftUI Lifecycle’ to come to Custom Keyboard Extensions! SwiftUI powers this app's advanced functionality, as well as some of its more unusual bugs. :) Disclaimer: This iPad app is available on Apple Silicon Macs, but macOS currently does not support keyboard extensions. Still waiting for that tablet Mac!

Verdict

The call

The clearest difference is rating: Fontastic at 4.8 against Keybuild's 4.1. Keybuild's advantage is monetization model (free vs paid) and update cadence (fortnightly vs every 5 weeks). On price, review sentiment, ratings volume and ads there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Fontastic costs $3.99 and Keybuild $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Fontastic holds the better App Store score, 4.8 against 4.1. Both are backed by a comparable volume of ratings — 48 and 49 respectively. Written reviews complicate that: 67% of Fontastic's written reviews are positive against 73% of Keybuild's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Fontastic ships an update every 5 weeks, Keybuild fortnightly. Both last shipped on October 27, 2026.
