# TRX vs Interval Clock

The clearest difference is rating: TRX at 4.6 against Interval Clock's 3.3. TRX also leads on ratings volume (21K vs 4) and review sentiment (48% vs 25%). Interval Clock's advantage is in-app purchases (none vs 15) and iOS requirement (5.1.1 vs 16.6). On price there is nothing between them.

Both are free to download. TRX sells 15 in-app purchases, starting at $4.99 per month. Interval Clock asks for nothing beyond the download.

TRX holds the better App Store score, 4.6 against 3.3. That said, the two scores are not equally well evidenced: TRX has 21K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 48% of TRX's written reviews are positive against 25% of Interval Clock's.
