The metabolism map shows the network of biochemical reactions. The metabolism of carbohydrates, lipids, amino acids and energy metabolism are shown on the interlinked competence levels I-III. The entry-level (I) offers an overview of some reactions. On levels II and III, the presentation is more comprehensive and detailed. On the expert level (III), there are references to hereditary diseases. The level-specific representation of chemical formulae, names of enzymes, factors, and transporters can be made visible by tapping. Overview chapters (synopsis) summarise metabolic pathways. There is a search function and the possibility to mark areas, attach notes and set bookmarks.

Verdict

The call

The clearest difference is rating: Pocket Heart at 4.7 against Biochemistry's 2.0. Pocket Heart also leads on ratings volume (492 vs 2) and review sentiment (78% vs 67%). Biochemistry's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 5 months vs every 11 months). On price, ads, in-app purchases and device support there is nothing between them.
