The latest version of Cell Surveys, 1.2.0, was last updated on July 21, 2026. ## Version history (last 5 releases) ### 1.2.4 — 2026-08-11 Getting started is quicker. • Signing up is one screen instead of four, with the same terms and privacy choices. • Prefer not to allow background location? The app now works without it — surveys record while it's open, and you can turn background collection on later in Settings. • Settings shows the correct app version again. ### 1.2.3 — 2026-08-11 Sign in with Apple is here. • Sign in with Apple, alongside Google — including Hide My Email. • Delete your account and all uploaded survey data from inside the app. • Google Drive backup connects separately, so it works whichever way you sign in. Plus faster maps, especially if you've been collecting for a while. • The coverage heatmap no longer slows down as your survey history grows. While a survey is running, refreshing the map used to re-read your entire history every 30 seconds — it now reads only what's new. • New signal readings appear on the map immediately, instead of re-processing every point already recorded. • Fixed saved survey timestamps being discarded when read back. • Less processing while a passive survey runs in the background. ### 1.2.1 — 2026-08-02 added county APN info for all US states. ### 1.2.0 — 2026-07-21 added apn/parcel OTA update fix. ### 1.1.0 — 2026-04-08 less notifications, Google Drive permissions prompt moved to settings. ## More apps by Dwas Woot LLC - [bujusjujus: TCG Restock Alerts](https://appshunter.io/ios/app/bujusjujus-tcg-restock-alerts/id6772565160) All apps by Dwas Woot LLC: https://appshunter.io/developer/1882376084 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
