# CallApp vs Track one GPS

The clearest difference is in-app purchases: Track one GPS at none against CallApp's 13. Track one GPS also leads on ads (none vs shown) and device support (3 vs 1). CallApp's advantage is update cadence (fortnightly vs every 4 months). On price there is nothing between them.

Both are free to download. CallApp sells 8 in-app purchases, starting at $6.99 per month. Track one GPS asks for nothing beyond the download.

CallApp ships an update fortnightly, Track one GPS every 4 months. The most recent releases landed on September 25, 2026 and September 14, 2026 respectively.
