# ChartTreker vs ProTA Mobile

The clearest difference is review sentiment: ChartTreker at 72% against ProTA Mobile's 0%. ChartTreker also leads on update cadence (every 6 weeks vs every 8 months) and ratings volume (27 vs 1). ProTA Mobile's advantage is rating (5.0 vs 4.5) and in-app purchases (none vs 2). On price, ads and device support there is nothing between them.

Both are free to download. ChartTreker sells 2 in-app purchases, starting at $3.99 per month. ProTA Mobile asks for nothing beyond the download.

ProTA Mobile holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: ChartTreker has 27 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 72% of ChartTreker's written reviews are positive against 0% of ProTA Mobile's, so the app with the better star average is not the one people write more warmly about.

ChartTreker ships an update every 6 weeks, ProTA Mobile every 8 months. The most recent releases landed on September 23, 2026 and July 5, 2026 respectively.
