Why are most Android notes apps so large?
An Android app's install size is mostly determined by the libraries it bundles. A typical notes app pulls in:
- A cloud sync SDK (Firebase, AWS Amplify, custom), 5–15 MB
- An account / authentication library, 1–3 MB
- Google Analytics or Firebase Analytics, 1–2 MB
- Crashlytics or Sentry, 1–2 MB
- Advertising SDKs (AdMob, Meta Audience), 3–8 MB
- A heavy UI toolkit or rich text editor, 5–20 MB
- Unoptimized images and unused locale files
That is how an app whose actual job is "save text and show it back" ends up at 50–100 MB.
How does SnapTask stay under 4 MB?
By not shipping the bloat:
- No cloud sync. Local SQLite via Room. No sync server, no SDK.
- No account system. Optional Pro is unlocked with a Gumroad license key, one HTTPS call, no auth library.
- No analytics or crash reporting. Zero telemetry SDKs.
- No ads. No advertising SDK at all.
- Jetpack Compose UI (built into Android), not a third-party framework.
- R8 minification + resource shrinking on release builds.
- 17 languages stored as Kotlin maps, not as bloated XML resources.
How does SnapTask compare on size to other notes apps?
| App | Approx install size | Has ads? | Has tracking? |

| Markor | ~6 MB | No | No |
| Google Keep | ~20 MB | No | |
| ColorNote | ~12 MB | Yes | Yes |
| Todoist | ~50 MB | Limited | Yes |
| TickTick | ~70 MB | Yes (free) | Yes |
| OneNote | ~80 MB | No | Microsoft |
| Notion | ~120 MB | No | Yes |
Does a smaller app actually mean better battery?
Usually yes. Battery drain comes from:
- Background sync (cloud apps poll or maintain push connections)
- Telemetry pings (analytics SDKs phone home periodically)
- Ad refresh cycles (banner ads request a new ad every minute)
- Wake locks (some apps keep the CPU awake longer than needed)
SnapTask has no advertising refresh or cloud-sync loop. Its persistent notification is an ongoing Android UI element. Actual battery use still varies by phone, Android version, and settings, so Android's per-app battery screen is the right place to measure it.
What features does SnapTask actually have at <4 MB?
- Notification-bar input for adding notes without opening the app
- Plain-text share target for compatible Android share actions
- Task list with three tabs (inbox / scheduled / done)

- Date shortcuts (tomorrow, +2d, 15 May, 15/03/2026)
- Local reminders with exact-alarm fallback
- Markdown export and backup/restore
- 17-language UI
- Light and dark themes
Every feature is local. No server, no sync, no account.

What is the lightest notes app for Android?
SnapTask at under 4 MB. Markor at around 6 MB is the next closest in the offline-first category.
Are there notes apps without ads on Android?
Yes. SnapTask, Markor, Google Keep, OneNote, and Apple Notes are all ad-free. SnapTask is the only one of those that is also under 4 MB and account-free.
Does SnapTask run a background service?
It runs a foreground notification, which Android requires for the persistent notification bar input. It does not poll, sync, or run any network calls in the background.
Will SnapTask drain my battery?
Package size alone does not determine battery use. SnapTask has no ad refresh or cloud-sync loop, but actual use varies by phone and settings. Check Android's per-app battery screen for a device-specific answer.
