# E vs Subscription Tracker

The clearest difference is update cadence: Subscription Tracker at every 3 weeks against E's every 4 months. E's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. E sells 2 one-off in-app purchases and Subscription Tracker sells 2 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

E ships an update every 4 months, Subscription Tracker every 3 weeks. Both last shipped on October 30, 2026.
