Digital field mapping app for geodiaries, fast surveys and GIS data collection.
About this app
SMASH is a digital field mapping application developed to perform fast qualitative engineering/geologic surveys and GIS data collection.
The main aim of SMASH is to have a tool that:
• fits in any pocket and can be always at hand, when needed
• gives the possibility to take geo-referenced and possibly orientated pictures during a survey, with further possibility to import them into GIS applications like gvSIG
• is able to easily exploit an Internet connection, if available
• is extremely easy to use and intuitive, providing just few important functions
The main features available in SMASH are:
• geo-referenced notes
• geo-referenced and oriented pictures
• gps track logging
• form-based data surveys
• easy export of collected data
• a map view for navigation with support for raster tiles and gpx vector data
• geopackage (OGC standard) support

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be eu.hydrologis.smash is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.10.5 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall SMASH — Smart Mobile App for Surveyor's Happiness first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of SMASH — Smart Mobile App for Surveyor's Happiness, and a listing is removed when the evidence for it stops holding up.
