# Triptoy vs Underground

The clearest difference is in-app purchases: Triptoy at none against Underground's 5. Triptoy also leads on ads (none vs shown) and review sentiment (100% vs 73%). Underground's advantage is update cadence (every 3 days vs every 57 months) and chart position (#119 vs unranked). On price, rating, monetization model and device support there is nothing between them.

Both are free to download. Underground sells 5 one-off in-app purchases. Triptoy asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Triptoy against 5.0 for Underground.
