Drivers are saying great things about the KeepTruckin trucker log book elogs app:
KeepTruckin and MyDAT Trucker load board are my two favorite trucker apps!
I am a BigRoad subscriber, and this has all the things I wished Big Road did.
Finally there's an Android App for our electronic logs and daily inspections that works and is legal! I'm done with pen and paper. This app rocks!
This is by far the best electronic logging program that I've ever used. Way better than BigRoad elogs.
I am using BigRoad driver logs at the time, but this program is much better on several fronts already.
This format beats BigRoad logbook on professionalism.
I was a BigRoad user from inception up until a week ago when I accidentally came across this app. I downloaded it and the rest is history. I'm hooked. BigRoad is now uninstalled; this app is far superior to BigRoad and its free, not $15 a driver.
Love this so much better then bigroad

Best elog app ever. I've used a lot of electronic logs. One was BigRoad. I give this one a thumbs up.

Mark Smolik on Dec 12, 2013:
Excellent app!! Far better than paper logs and several steps above Qualcomm's now p.i.t.a. electronic logs.
Donnie Whitley on Nov 23, 2013:
Love it!!!!!! Thought I would not want to use electronic logs, this is the best. No sloppy logs no trying to remember where I been. Have received many compliments from multiple states on the program. Thanks BigRoad.
Ashton Bannister on Nov 15, 2013:
Saves me a lot of time real easy to get my logbook done up I'd say 1/10th of the time to do up your DVIR and Daily log. I occasionally forget to update my log book during the day this app does it for me and always keeps me legal!
We recommend keeping your phone or tablet plugged in to a charger for best GPS coverage. If the battery is low, the app will check GPS location less often.
The BigRoad app asks for access to your contacts and phone so that you can easily send check-in messages, documents and copies of your log using your contact manager. We do not copy or store any of your contact information.

Truck Parking Europe is the largest free European platform for truck parking facilities. The constantly growing, community-based parking database contains both officially designated truck and motorway parking places and car parks, as well as other suitable parking places, e.g. in industrial areas, all updated and evaluated by a pan-European community.
Everyone who is on the road everyday is familiar with the situation: due to strict regulations for driving and rest times and the lack of sufficient parking places on the main traffic corridors, searching for a suitable parking place is a problem – especially if you want to use as much as possible of the allowable driving time.
Truck Parking Europe is the solution to this problem. The comprehensive parking database simplifies your daily search for parking facilities on the European highways. In addition to official parking space data, the parking app takes into account suitable, good parking places away from the long-distance highways, based on the personal experience of a pan-European community. The extensive parking place evaluation function offers more added value, helping you with questions such as which parking places you should avoid and which are preferable, and which ones are lit, supervised or next to supervised areas such as factory sites.
Find parking places that meet your needs and benefit at the same time from the options of adding your own parking places to the database, correcting and evaluating existing data, and sharing parking facilities with others. Take advantage of the pan-European community of Truck Parking Europe!
The app and participation are free. Please note that the app only provides a platform for data which is essentially generated by the users of the app. Suggestions from truck drivers for additional features and enhancement of the app are always welcome at www.truckparkingeurope.com.
Extensive update to the entire app with many new functions
- NEW: The app now includes almost 12,000 car parks with a large number of ratings and reports. Thank you to all drivers who have contributed so far!
- NEW: Drive mode. View parking spaces along the route that can be reached with a maximum detour of 6 kilometres (there and back). The list is updated continually during the journey and shows the distance and additional detour to the parking spaces. All you have to do is enter your direction of travel (e.g. direction "Rotterdam").
- NEW: Enter your remaining driving time to see which parking spaces can still be reached.
- NEW: Enter the occupancy status of HGV parking spaces and benefit from notifications from other drivers. This function can be used within a 1,200-metre radius.
- NEW: Parking spaces for which occupancy information is available are shown on the map and lists in green, yellow or red. Depending on how old the notification is, the icon will become paler. The status will expire after a maximum of 3 hours.
- NEW: The radius search for parking spaces can now be performed for the driver's present location or for a point on the map.
- NEW: You can now view the rankings and compare your points with others – weekly, monthly or in our all-time rankings. There are points for creating parking spaces (10 points), modifying and rating (2 points) and notifying of the current occupation status (1 point).
- NEW: The new attribute "Power supply" is now available.
- NEW: The coordinate or address of a selected parking space can be transferred to the navigation system installed on the smartphone.
- NEW: The number of parking spaces is now displayed in the app.
You can use 'Share' to send your trip info via email, messaging etc. You can back up your trip info to Google Drive, Note Everything, etc as a readable note.
I have received emails asking for a BOL field. As there may be multiple pick ups and stops, I find it best to store the BOL number with the Shipper Info or Receivers Info.
Please use the force close error reporting feature to send me the error data. Just complaining about it in the review does no one any good, including you. You can also email me and let me know what has happened. Without the data, I have no way of knowing what to fix.
*** When upgrading from Lite to the Paid Version, you will lose all stored data stored in the Lite Version, on un-install. I would suggest you keep the Lite on your device until all data is no longer needed or manually transfer the data to the Paid Version.
If the driver does need a hard copy scale ticket for billing purposes, they can still pick up a printed CAT Scale ticket at the fuel desk within an hour after weighing using the Weigh My Truck™ application.
Professional truck drivers are able to create an account online that will store basic truck information and email preferences, as well as keep a record of past weigh transactions.
Die FERNFAHRER Autohöfe App ist ein unverzichtbarer Begleiter für alle Lkw-Fahrer in Europa. Die App zeigt alle Autohöfe und Tankstellen Europas auf einer zoombaren Karte. Nach einem Tap auf das Symbol können Sie alle wichtigen Informationen zu Autohof oder Tankstelle abrufen, von den Öffnungszeiten bis hin zur Ausstattung.
NEU: Reservieren Sie sich einen Parkplatz auf einem Autohof. Auf der Detailseite des Autohofs mit diesem Service finden Sie einen Button „Lkw-Parkplatz reservieren“ über den Sie zur Buchungsplattform des Dienstes UnserParkplatz.de gelangen.
Bewerten Sie die Autohöfe! Vergeben Sie je fünf Sterne in den Kategorien Parkplatz, Qualität des Essens, Sauberkeit der Duschen, Freundlichkeit des Personals, Preis-Leistungsverhältnis.
Mit der erweiterten Suchfunktion können Sie nach Namen, entlang einer beliebigen Autobahn oder aber auch entlang einer individuellen Route suchen. Über die Umkreissuche finden Sie Autohöfe und Tankstellen auch in direkter Nähe zu Ihrer aktuellen Position. Dabei können Sie selbst auswählen, welche Ausstattung verfügbar sein muss – ob Dusche, Restaurant oder Biodiesel.
Falls Sie gerne spontan eine Pause einlegen oder den nächsten Autohof nicht verpassen wollen, benachrichtigt Sie die App auf Wunsch kurz bevor Sie an den nächsten Autohof kommen.
In der Rubrik News versorgt das FERNFAHRER-Redaktionsteam Sie mit allen nützlichen Infos und Neuigkeiten aus der Welt der Lkw. So verpassen Sie keine wichtige Neuerung im Straßenverkehr und erfahren sofort, wenn es in der Branche etwas Neues gibt.
Falls Ihnen oder Ihrem LKW einmal etwas fehlt, hilft Ihnen die stetig wachsende Rubrik Servicepartner, die nächste Werkstatt etc. zu finden.
Die FERNFAHRER Autohöfe App ist auch auf Englisch, Französisch, Polnisch, Holländisch, Spanisch, Italienisch und Ungarisch erhältlich.
HINWEISE: Damit Ihnen die App die nächsten Autohöfe melden kann, müssen die Ortungsdienste in den Einstellungen Ihres Smartphones aktiviert sein. Außerdem ist dann der GPS-Empfang im Hintergrund aktiv. Das kann den Akku schnell entladen.
Bei Nutzung der Services im Ausland können zusätzliche Roaming-Kosten entstehen.
Using the newest technology available, our app uses HTML5 to work on just about every mobile device on the market today. This technology allows your device to automatically download the app and save it to your device for use offline. It also auto updates to the newest version when you connect via the Internet.
HTML5 is supported my most new mobile devices. This allows us to have the same app work on the iPad, iPhone, Blackberry, and Android without needing to go through each individual app store.
While the app works through your mobile device's browser, it isn't just another website. Using HTML5, your device is able to download the files and run them even when you aren't connect to the Internet. It will use the cached (stored) version of the app while you are offline.
If you have hit and miss 3G service, then just go into "airplane mode" and the app will stop trying to check for the newest updates and just run off of the previously download version.
Installing the app on each device is a little different but the concept is the same. You just need to "add to your home screen". Once you add the app to your home screen, your mobile device will automatically download and save all of the required files so that your app can run offline.
