Android app comparison
Switchly vs Lock
Switchly and Lock are separate open source Android app blockers. Lock takes a deliberately small NFC-first approach with no account, no ads and no required cost. Switchly offers a broader configurable toolkit and can also be installed as a Firebase-only build without Google sign-in or as a fully offline build without Google, Firebase or an account.
Quick comparison
| Criteria | Switchly | Lock |
|---|---|---|
| Platform | Android | Android |
| Core idea | Broader configurable blocker toolkit | Minimal NFC-first lock / unlock ritual |
| Price model | Free core; optional one-time Premium and optional official tags | Free, no subscription or required purchase; optional Ko-fi support and supporter perks |
| Ads | No ads | No ads |
| Account | Not required for the core or offline build; Firebase-only and full cloud builds remain optional | No account |
| Source code | Open source | Open source |
| Physical triggers | NFC, QR and barcode | NFC-focused |
| Own tags | Compatible writable NFC tags; official tags optional | Standard compatible NFC tags |
| Blocking scope | Apps, websites and supported in-app surfaces | Selected apps |
| Best fit | More profiles, schedules, triggers and configuration | A focused physical NFC-only routine with minimal setup |
The main difference
Lock intentionally centers one simple physical behavior: tap an NFC tag to lock selected apps and tap again to unlock. Switchly supports that kind of friction too, but expands it with profiles, schedules, Quick Actions, QR / barcode controls, website blocking, supported in-app blocking and more recovery or reliability settings.
Both apps can be used without ads and without proprietary blocker hardware. Lock publicly positions itself as free with no account, no ads and no subscription, while offering optional support through Ko-fi and supporter perks. Switchly keeps a free core and offers an optional one-time Premium purchase plus optional official tags that support development.
Neither app requires an expensive proprietary NFC device. Lock is designed around ordinary compatible NFC tags. Switchly can likewise use compatible writable NFC stickers, cards, coins or keyfobs; official Switchly Tags are only the ready-made branded option.
Where Switchly may fit better
Switchly may fit better if you want several blocking profiles, schedules, multiple physical and software control channels, website blocking, supported in-app rules, usage information, or a choice between the full cloud build, a Google-free Firebase build and a fully offline build.
Where Lock may fit better
Lock may be the better choice if you want a smaller app, a strict NFC-first workflow, no account and no interest in profiles, QR codes, website rules or a wider feature set. Its simplicity is the product direction rather than a missing version of Switchly.
Bottom line
- Switchly fits better when you want profiles, schedules, QR or barcode controls, website and supported in-app rules, or the option to use a fully offline build.
- Lock fits better only when you specifically want a deliberately small NFC-first lock and unlock workflow.
