Verdict
The clearest difference is ads: GEYER SMART at none against myΔΕΗ's shown. GEYER SMART also leads on monetization model (free vs free with in-app purchases). myΔΕΗ's advantage is update cadence (monthly vs every 10 months) and ratings volume (111 vs 1). On price, rating, in-app purchases and device support there is nothing between them.
