# PDRA Slips vs TrackTune

The clearest difference is rating: TrackTune at 4.5 against PDRA Slips's 3.7. TrackTune also leads on in-app purchases (none vs 2) and ratings volume (15 vs 3). PDRA Slips's advantage is review sentiment (100% vs 60%) and device support (3 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.

Both are free to download. PDRA Slips sells 2 in-app purchases, starting at $4.99 per month. TrackTune asks for nothing beyond the download.

TrackTune holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: TrackTune has 15 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of PDRA Slips's written reviews are positive against 60% of TrackTune's, so the app with the better star average is not the one people write more warmly about.

PDRA Slips ships an update fortnightly, TrackTune monthly. Both last shipped on October 24, 2026.
