# SFPL vs My Device

The clearest difference is review sentiment: My Device at 100% against SFPL's 28%. My Device also leads on rating (4.3 vs 4.0). SFPL's advantage is ads (none vs shown) and update cadence (every 4 months vs every 27 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

My Device holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: SFPL has 50 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 28% of SFPL's written reviews are positive against 100% of My Device's.

SFPL ships an update every 4 months, My Device every 27 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
