Toolchain

A real Go environment, verified in the source

Bundled Go 1.27.1

The Go toolchain ships inside the app and runs on device. No remote build server, no sign-in.

build · run · test · vet · gofmt

The commands you already use, wired into a touch-first workspace with a Problems and Output panel.

Multi-package projects

Real directory layouts with several packages, all sources fully editable in the app.

Projects that stay organised

Folders, tags, favorites and autosave keep work in place between sessions.

Import from GitHub and Files

Pull in a repository snapshot or bring sources from the Files app to keep editing on device.

Checksum-verified vendoring

Pure-Go dependencies are vendored with checksum verification before they enter a project.

Learning

Practice with the compiler in hand

31lessons: Structured across nine units, from syntax to composition.
20practice challenges: Question-and-answer challenges, separate from the 31 course lessons.
9Concurrency Lab scenarios: Instrumented goroutine timelines make scheduling visible.
14interview questions: Answer, then compare against the reference.
12spot-the-bug exercises: Find the defect in realistic Go snippets.
0AI in the Idiom Coach: The Idiom Coach is deterministic rule-based analysis, not a language model.

In the app

No account. No subscription. No ads. No analytics.

The native app has no sign-in, no subscription, no advertising and no analytics or crash reporting SDK. Projects, progress and settings stay on your device unless you export or share them yourself, or they travel in your own device backups. Achievements are local; Game Center is not used. Full details are in the privacy statement.

Source and licence

Publicly readable, not open source

The GopherForge repository is public so anyone can read the code, review the compiler integration and check security claims. It is proprietary software: all rights are reserved, and public visibility grants no licence to use, copy, modify or redistribute it.

Honest limitations

What GopherForge does not do

Can I use cgo or hand-written assembly?: No. cgo and native assembly are not supported. Guest programs are pure Go.
Can programs I write make network calls?: No. Guest Go programs cannot access the network. Networking is only used by the app itself for optional source imports, package search and package installation.
Are transitive module dependencies resolved automatically?: Not yet. Transitive modules must be installed separately, each one explicitly.
What happens if my program loops forever?: There is no guaranteed stop for an infinite loop. If a program stops responding, close the app and reopen it.
Has this been validated on real hardware?: Offline and thermal validation on physical devices is still pending. The compiler integration has been demonstrated in the iOS Simulator.
Is GopherForge open source?: No. The repository is publicly readable for review and evaluation, but the source is proprietary and all rights are reserved. See the LICENSE for the exact terms.
Is the app on the App Store?: Not yet. The App Store release is being prepared, so there is no download link or rating on this page. The planned launch price is confirmed: US $6.99, with US $4.99 in Ukraine.
How much does GopherForge cost?: It is a one-time purchase: US $6.99 as the base price, with a regional override of US $4.99 for Ukraine. Other regions use the App Store's localized pricing derived from the $6.99 base. There is no subscription and no in-app unlock.
Why does the price look different in my country?: The App Store converts the base price into each region's price tier, so the local amount shown at purchase varies with region, currency and taxes. The App Store price at checkout is always the price that applies.
Does the app need an internet connection?: Only for optional work: importing sources, searching packages and installing them. Editing, building, running and testing happen on device.
