AtoB: Find and Save on Fuel

Review by eFreeware

Fuel is one of the few costs in trucking that a driver can still influence, but only if they know where the discounts are and can steer the route toward them. Hunting through station apps and loyalty programs one at a time is slow, and it rarely tells you whether a cheaper stop is worth the detour. AtoB is built around that gap: it gathers discounted fuel prices, plans routes around them and puts fleet card controls in the same place.

The app sits in the Auto & Vehicles category on Google Play. It has been available since the end of June 2022 and was last updated in early September 2026. It is free, carries no ads and offers no in-app purchases.

Discounts that are the point of the app

The headline feature is straightforward: the app surfaces fuel discounts at stations you already use. For truck diesel, the developer puts the average saving at 42 cents off per gallon, and the network includes TA, Petro, TA Express, 7-Eleven, Speedway and RaceTrac among others. For unleaded, the average discount is quoted at 5 cents per gallon at stations such as Speedway, 7-Eleven, Casey's, Kwik Trip and Chevron.

Those averages matter more than they might look. A 42-cent saving on a hundred-gallon fill is real money, and it repeats every time the truck is topped up, which is why fuel discounting has become such a competitive corner of the trucking world. The 5-cent average on gasoline is a much smaller number, so the value of the app leans heavily toward diesel fleets rather than someone filling a single passenger car now and then.

What I like about the framing is that it does not pretend to be a general price comparison tool for every driver. It is pointed at the transportation industry, and the station list reflects that: truck stops first, with convenience store chains filling in the gasoline side. If your vehicles run on diesel and cover serious miles, the discount structure is exactly the kind of thing worth checking before you commit to a fuel card.

FuelMap and route planning

FuelMap is the planning half of the app. Rather than showing you the nearest station, it works out a route with stops chosen for the biggest discount and the lowest retail fuel cost, so the savings are baked into the trip before the truck leaves the yard. For a dispatcher or an owner-operator mapping out a long haul, that is a more useful question than "where is the closest pump".

The second half of that idea is the handoff. Once the route is set, you can send it to the navigation app you already prefer with a single tap. That is a small detail but a sensible one: it means AtoB does not ask you to learn a new turn-by-turn system or abandon the one you trust on the road.

I would expect this combination to appeal most to people who plan loads in advance rather than improvising. If your fuel stops are decided the night before, the app has something to work with. The value comes from planning around discounts rather than discovering them after the fact.

The fleet side of the same app

AtoB also handles the administrative side of fleet fuel. You can set controls such as spend limits, operational hours and merchant blacklists or whitelists, which is the sort of thing a fleet manager needs to keep drivers inside policy without calling each one individually. Cards can be activated and deactivated from the app, and balances can be paid there as well.

There is also a security feature worth noting: cards are unlocked from the app when it is time to fuel, and the developer's point is that a locked card is useless to anyone else who gets hold of it. For a small carrier, that is a meaningful control, since fuel cards are an obvious target for misuse.

Having discounts, routing and card administration in one place is the real argument for the app. A fleet manager who already runs AtoB cards gets a single dashboard for the parts of fuel spending that usually live in three different systems.

What the app assumes about you

The trade-offs here are structural rather than hidden. This is a fuel card companion, so the app is only as useful as the overlap between the stations it covers and the roads your vehicles actually run. A regional operation far from the major truck stop chains will see less of the benefit than a long-haul fleet on interstate corridors.

The gasoline side is modest by comparison, with an average discount of 5 cents per gallon, so a driver filling a single car should weigh whether that is enough to bother with. The diesel side is where the numbers are worth attention.

Spend limits, merchant controls and card activation are fleet tools, and they make most sense when someone other than the driver is responsible for the bill. There is no charge to install the app, no advertising and nothing to buy inside it, so trying it costs nothing beyond the time to see whether the station coverage fits your routes.

A tool for diesel-heavy operations

The clearest fit is an owner-operator or small carrier running diesel trucks on regular long routes. The combination of a 42-cent average diesel discount, route planning around the cheapest stops and card controls in a single app is a coherent package for that operator.

Fleet managers at larger operations should find the controls familiar ground: limits, hours, merchant lists and card status are the levers they pull anyway, and having them on a phone rather than only at a desk is convenient for anyone supervising drivers remotely. The 4.6 average from 693 ratings suggests the people using it are broadly satisfied.

A driver filling one gasoline car will find less here. The unleaded discounts average 5 cents per gallon. The app is built for commercial fuel spending, and that is where it should be judged.

Worth installing for regular diesel fill-ups

AtoB is a focused app that appears to do three related jobs well: it locates discounted fuel, plans routes around the best prices and gives fleet managers control over cards and spending. The diesel discounts are the strongest part of the offer, and the free, ad-free, purchase-free setup removes most of the hesitation about trying it.

If you run diesel trucks and your routes cross the station chains the app covers, installing it to compare prices against your current fuel arrangements is a reasonable first step. If you manage a fleet, the card controls alone may justify a look. For a single gasoline car, the savings are small enough that the app is unlikely to change your habits.

The recent update is limited to bug fixes and performance improvements, which tells you the core feature set is settled.
