# Glycemic Index vs Satellite Tracker

The clearest difference is in-app purchases: Glycemic Index at none against Satellite Tracker's 3. Glycemic Index also leads on ads (none vs shown) and review sentiment (31% vs 13%). Satellite Tracker's advantage is update cadence (every 3 months vs every 26 months) and iOS requirement (15.1 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Satellite Tracker sells 3 in-app purchases, starting at $2.99 per month. Glycemic Index asks for nothing beyond the download.

Glycemic Index holds the better App Store score, 2.2 against 2.0. That said, the two scores are not equally well evidenced: Glycemic Index has 15 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 31% of Glycemic Index's written reviews are positive against 13% of Satellite Tracker's.

Glycemic Index ships an update every 26 months, Satellite Tracker every 3 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
