5 Best Mobile Development Tools for Solo Developers (2026)
Shipping an app alone means build, release, monetization, monitoring, and design all land on you. These five tools — Expo, Fastlane, RevenueCat, Sentry, and Mobbin — cover the whole loop.
A solo mobile developer does five jobs: build the app, get it into the stores, charge for it, find out when it breaks, and make it look like a team designed it. This is the smallest set of tools that covers all five without hiring anyone.
Every entry is in the Mobile directory.
| Tool | Covers | Pricing |
|---|---|---|
| Expo | Build + OTA updates + submission | Freemium |
| Fastlane | Release automation | Open source |
| RevenueCat | Subscriptions and paywalls | Freemium |
| Sentry | Crash reporting | Freemium |
| Mobbin | UI patterns and design reference | Freemium |
1. Expo — the fastest path from code to a store build
Covers: development builds, cloud builds, over-the-air updates, store submission.
Expo removes most of the native toolchain from your day. Managed builds mean you are not maintaining Xcode and Gradle configs alone, and OTA updates let you push a fix without waiting on review. For a one-person React Native project it is the single highest-leverage choice. See Expo.
2. Fastlane — stop doing releases by hand
Covers: signing, screenshots, metadata, uploads — scripted.
A manual release is twenty minutes of clicking and one chance to get it wrong. Fastlane turns it into a command, which matters most exactly when you are shipping alone and tired. Open source, and it runs on any CI. See Fastlane.
3. RevenueCat — subscriptions without writing StoreKit
Covers: in-app purchases across iOS and Android, entitlements, paywalls, revenue analytics.
Billing is the part of a mobile app most likely to break quietly and cost you money. RevenueCat gives you one SDK across both stores, a real entitlement model, and the analytics to see whether a paywall change actually helped. Free until meaningful revenue. See RevenueCat.
4. Sentry — find out before your users tell you
Covers: crash reporting, error tracking, release health, performance.
Store reviews are a terrible bug tracker. Sentry tells you which release broke, on which device, and with what stack trace — usually before the first one-star review lands. See Sentry.
5. Mobbin — design reference instead of a designer
Covers: real screenshots and flows from shipped apps.
Solo developers do not lack taste, they lack references. Mobbin catalogues real screens and flows from production apps, so onboarding, paywall, and settings screens can start from a pattern that already works. See Mobbin.
The minimum stack
- Building: Expo (or React Native bare, if you need it).
- Shipping: Fastlane.
- Earning: RevenueCat.
- Watching: Sentry.
- Designing: Mobbin.
That is the whole loop, and four of the five have a free tier that lasts well past launch.
FAQ
Do I need Expo if I already use React Native?
Not strictly, but you almost certainly want it. Bare React Native means owning the native build setup yourself — a real cost when there is only one of you.
Is RevenueCat worth it over StoreKit directly?
For a solo developer, yes. Cross-platform entitlements, receipt validation, and subscription edge cases are far more work than they look, and the free tier covers early revenue.
What about Firebase?
Firebase overlaps here — analytics, push, and a backend in one. It pairs well with this list; it just does not replace release automation or subscription infrastructure.
The rest of the stack — frameworks, backends, and store tooling — is in the Mobile directory.
