The clearest difference is rating: Moozumo at 4.3 against Z5 Mobile's 3.7. Z5 Mobile's advantage is in-app purchases (none vs 4) and ratings volume (127 vs 3). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Moozumo sells 4 in-app purchases, starting at $1.99 per month. Z5 Mobile asks for nothing beyond the download.
