Verdict
The clearest difference is rating: Phyto at 4.8 against Whale Encyclopedia's 4.2. Phyto also leads on in-app purchases (none vs 3) and review sentiment (64% vs 50%). Whale Encyclopedia's advantage is update cadence (fortnightly vs every 10 months) and ratings volume (20 vs 6). On price, ads, monetization model and device support there is nothing between them.
