Verdict
The clearest difference is in-app purchases: Triqtraq LE at none against iSequence HD's 8. Triqtraq LE also leads on update cadence (every 2 weeks vs every 3 months) and device support (3 vs 1). iSequence HD's advantage is rating (4.2 vs 3.8) and ratings volume (33 vs 4). On price, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. iSequence HD sells 8 one-off in-app purchases. Triqtraq LE asks for nothing beyond the download.
iSequence HD holds the better App Store score, 4.2 against 3.8. That said, the two scores are not equally well evidenced: iSequence HD has 33 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 77% of iSequence HD's written reviews are positive against 83% of Triqtraq LE's, so the app with the better star average is not the one people write more warmly about.
iSequence HD ships an update every 3 months, Triqtraq LE every 2 weeks. Both last shipped on November 6, 2026.
