# Growlink vs i

The clearest difference is rating: i at 5.0 against Growlink's 1.8. i also leads on ads (none vs shown) and monetization model (free vs ad-supported). Growlink's advantage is update cadence (monthly vs every 6 months) and ratings volume (5 vs 1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

i holds the better App Store score, 5.0 against 1.8. That said, the two scores are not equally well evidenced: Growlink has 5 ratings behind it against 1, so its average is the more settled of the two.

Growlink ships an update monthly, i every 6 months. The most recent releases landed on September 25, 2026 and October 7, 2026 respectively.
