# PC vs TBM Performance

The clearest difference is review sentiment: TBM Performance at 88% against PC's 19%. TBM Performance also leads on rating (5.0 vs 3.0) and update cadence (every 2 months vs every 5 months). PC's advantage is ads (none vs shown) and monetization model (free vs ad-supported). 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.

TBM Performance holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: TBM Performance has 14 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 19% of PC's written reviews are positive against 88% of TBM Performance's.

PC ships an update every 5 months, TBM Performance every 2 months. The most recent releases landed on September 20, 2026 and July 23, 2026 respectively.
