Verdict

The call

The clearest difference is ads: appodixi at none against myΔΕΗ's shown. appodixi also leads on monetization model (free vs free with in-app purchases). myΔΕΗ's advantage is update cadence (monthly vs every 5 months) and review sentiment (20% vs 0%). On price, in-app purchases, device support and iOS requirement there is nothing between them.
