# MFIT Personal vs Bird ID

The clearest difference is rating: MFIT Personal at 4.9 against Bird ID's 4.6. MFIT Personal also leads on ratings volume (4K vs 93) and review sentiment (40% vs 29%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. MFIT Personal sells 1 one-off in-app purchase and Bird ID sells 7 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

MFIT Personal holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: MFIT Personal has 4K ratings behind it against 93, so its average is the more settled of the two. Written reviews point the same way: 40% of MFIT Personal's written reviews are positive against 29% of Bird ID's.

Both ship on a similar rhythm, roughly fortnightly. Both last shipped on October 29, 2026.
