Recommended hardware


All iPhones and iPads of the same age or newer than the iPhone 6 will run the Trilobite Solutions app.

Warning: WIFI-only iPads do not have GPS – therefore cannot determine your location when you are in the field, so although they will run the app they are of little use in the field.


Ensure that your Android phone or tablet has at least 32 GB of storage (suggest 64 GB) and at least 2 GB of RAM (4 MB or more is better). Data layers and the import of .geojson files is disabled by the app on Android devices with less than 2 GB RAM because these devices do not have sufficient hardware resources to run these functions reliably. Place your finger on ‘’ at the bottom of the map view for half a second to show the amount of available RAM on your phone.

Warning: Some Chinese-made Android phones are problematic – eg. ZTE85, ZTE84

Other notes

We recommend that you buy a shockproof gel/silicon/rubber protector for your phone or tablet – easily sourced on eBay.

Note that subscriptions purchased on Android devices cannot be transferred to Apple devices. If you replace an Android phone/tablet with an iPhone/iPad, you need to cancel your Android (Google Play) subscriptions, and buy new Apple ( iTunes) subscriptions. See for more details.
