Compose Multiplatform - iOS/Android Development with Kotlin
provider

1

Compose Multiplatform - iOS/Android Development with Kotlin (2026)

4.3
(538 reviews)
byStefan Jovanovic

A two-hour, single-project crash course that ships one Kotlin currency app to both iOS and Android with fully shared Compose UI, Ktor networking and an offline cache.

Best for: Working Android developers who know Jetpack Compose and want a fast, working KMP template rather than a lecture series.

icon
Pros
icon
Cons
    • One real app covers networking, local caching, MVVM and Clean Architecture in 2.3 hours
    • Shared UI on both platforms, not just shared business logic
    • Updated August 2026 with a dedicated course updates section
    • One experienced Android developer says it works as a reusable KMP template
    • Pace is the top complaint across nearly every low-star review; code is often pasted, not explained
    • Uses Realm for local storage, which two reviewers found deprecated and replaced on their own
    • No coverage of platform-specific cases like permissions or notifications

Android Lifecycles Masterclass
provider

2

Android Lifecycles Masterclass (2024)

4.9
(455 reviews)
byVasiliy Zukanov

Ten focused hours on Android component lifecycles, configuration changes and process death, from a course whose 455 reviews average 4.9 stars.

Best for: Working Android developers who keep hitting lifecycle bugs or have an interview with lifecycle questions coming up.

icon
Pros
icon
Cons
    • Explains why each callback exists, not just the order, so reviewers say the concepts stick.
    • Dedicated sections on configuration changes and process death, the two areas the course singles out for tricky bugs.
    • Tutorial code lives in an open-source demo app built to test tricky lifecycle behavior.
    • Concise at about 10 hours; one reviewer says the shorter length is the perfect fit.
    • No Jetpack Compose lifecycle module, which one reviewer flagged as a gap.
    • One low-star review says on-screen coding mistakes and corrections break the flow.
    • Last updated March 2024, and no quizzes or exercises to check understanding.

Create Business Applications with AppSheet
provider

Create Business Applications with AppSheet (2019)

4.4
(5,083 reviews)
bySantiago Uribe Montoya

A free, one hour tour of Google's no-code AppSheet builder that shows spreadsheet users what the platform can do, with 41,000 students and a 4.4 rating despite a 2019 update.

Best for: Spreadsheet users who want a quick, free look at what AppSheet can build before spending real time on it.

icon
Pros
icon
Cons
    • Free and only an hour, so it costs nothing to find out if AppSheet fits your problem
    • Clear step-by-step structure across data, UX, automation, security and publishing
    • Reviewers say it left them comfortable moving on to more advanced AppSheet material
    • Taught by a practitioner who builds AppSheet apps for businesses, with two co-instructors
    • Last updated August 2019, so the screens show AppSheet's old editor
    • Shows features rather than building one app end to end; styling is barely covered
    • No way to ask the instructor questions, and one reviewer wanted captions and a search option

4.5
(432 reviews)
byOak Academy

Best for: People who know a little Kotlin and want a gentle, line-by-line walk through Compose basics with two small apps.

icon
Pros
icon
Cons
    • Slow, line-by-line explanations that reviewers say suit true Compose newcomers
    • Two full projects, a to-do list and a math game, plus a section on publishing to Google Play
    • Updated in September 2026, three years after its 2023 launch
    • Short at about 10 hours, with 10 quizzes to check the basics
    • No MVVM, Room, or SQLite, which two reviewers wanted in the projects
    • Navigation section uses the older API, not type-safe navigation, per a one-star review
    • Needs basic Kotlin despite the no-prerequisites claim; one reviewer says total beginners get lost

The Complete Android 16 Course [Part 2] - Jetpack Compose (2026)

4.5
(291 reviews)
byAbbass Masri

A project-heavy Jetpack Compose course that goes from composables and state through MVVM, Room, Retrofit, Hilt and Firebase to a Google Maps Uber clone, rated 4.5 from 291 reviews.

Best for: Kotlin-comfortable learners who want to build a stack of Compose apps with Room, Retrofit, Hilt and Google Maps rather than study one topic.

icon
Pros
icon
Cons
    • Ten build-along apps, from a Room note app to a 300-minute ecommerce project and an Uber clone
    • Reviewers say Masri explains in detail and shows where a concept applies, not just how it works
    • Covers Hilt, Retrofit, Room, Firebase and Google Maps in one place, with about 500 minutes on Maps alone
    • Last updated September 2026, so the Compose material is still being refreshed
    • Several sections ship missing or wrong source code, including an XML project attached to the ecommerce section
    • Some lectures use outdated APIs and one reviewer says the instructor did not respond to questions
    • One reviewer says the zooming while code is typed makes it hard to follow after looking away
