# Link Master vs Radiant Lines

The clearest difference is review sentiment: Radiant Lines at 100% against Link Master's 45%. Radiant Lines also leads on update cadence (monthly vs every 5 months) and rating (4.6 vs 4.3). Link Master's advantage is ratings volume (224 vs 11) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Link Master sells 10 one-off in-app purchases and Radiant Lines sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Radiant Lines holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Link Master has 224 ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 45% of Link Master's written reviews are positive against 100% of Radiant Lines's.
