# APECS vs C

The clearest difference is review sentiment: C at 100% against APECS's 18%. C also leads on rating (5.0 vs 1.7) and update cadence (every 5 days vs monthly). APECS's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. APECS sells 11 in-app purchases, starting at $2.49 per month and C sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

C holds the better App Store score, 5.0 against 1.7. Both are backed by a comparable volume of ratings — 7 and 5 respectively. Written reviews point the same way: 18% of APECS's written reviews are positive against 100% of C's.

APECS ships an update monthly, C every 5 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
