Most-Requested Missing Features

Features users are literally asking for in their reviews, ranked by demand.

#1: Maintenance and service cost tracking

High Demand
"I had maintenance and cost logs and that seems to be a completely missing feature for the iOS version"
"Using for Android for few years. Excellent!!! On iPhone only fuel can be entered not maintance like battery, brakes etc"

#2: Automatic iCloud backup and cross-device sync

High Demand
"Unsure why the data is not auto-backed up to iCloud like all other apps on iOS"
"No way to sync iOS and Android apps. Completely different set-ups. How completely useless"

#3: Electric vehicle and PHEV charging tracking

Medium Demand
"You can set it up for a PHEV to track fuel and electricity but will not let you log any charge ups only fuel ups"
"First EV log showed proper units of measure. All logs after that showed EV as fuel instead"

#4: Ability to add/edit gas station locations

Medium Demand
"Many stations are missing or incorrect and no option to edit or report"
"FAQ also states I can add stations. But that too is no where to be found"

#5: Motorcycle and other vehicle type support

Low Demand
"It doesn't have any motorcycle categories so I don't have use for it. I don't want to confuse the stats of other vehicles by pretending that my Husqvarna is a Cadillac"

Build Recommendations

Prioritized actions based on user demand and market opportunity.

Build cloud-first with automatic iCloud/Google Drive backup from day one

22% of complaints involve catastrophic data loss. Making reliable sync the core architecture—not an afterthought—immediately differentiates from competitors and addresses the #1 pain point

Launch with full feature parity across iOS and Android, including maintenance tracking

19% of reviews cite iOS missing critical features like maintenance logs. Many users switched platforms and were shocked by feature degradation, creating opportunity to win frustrated Android-to-iOS switchers

Enable retrospective entry without GPS requirements and manual station addition

Users need flexibility to enter data after the fact (traveling, motorcycles, inconvenient timing). Current apps force real-time GPS entry, creating friction for common use cases

Include EV/PHEV dual-fuel tracking with both gas and electric charging logs

Multiple users explicitly requested hybrid/EV support that competitors claim to offer but don't fully implement. Growing EV market represents greenfield opportunity

Offer free CSV export and one-time pro purchase (no subscription) with transparent data ownership

Users are abandoning apps over paywall-locked exports and forced subscriptions. Positioning as 'your data, your control' with reasonable one-time pricing builds trust and reduces churn
