# MIR Spiro vs VenTrainer

The clearest difference is rating: MIR Spiro at 4.5 against VenTrainer's 3.3. MIR Spiro also leads on update cadence (every 2 months vs every 4 months) and iOS requirement (12.4 vs 15.0). VenTrainer's advantage is review sentiment (33% vs 17%) and ratings volume (12 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

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

MIR Spiro holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: VenTrainer has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 17% of MIR Spiro's written reviews are positive against 33% of VenTrainer's, so the app with the better star average is not the one people write more warmly about.

MIR Spiro ships an update every 2 months, VenTrainer every 4 months. Both last shipped on October 7, 2026.
