### 5/5 — Lässt kaum Wünsche offen

*2025-06-03*

Übersichtlich aufgebaut, Lernmodus, für weitere Infos jeweils Links zu Wikipedia. Seit dem Update fehlerfrei.

### 5/5 — Super

*2024-07-04*

Die bislang umfangreichste Aminosäuren App

### 1/5 — Fehlerhaft

*2024-04-30*

Fehlerhafte Darstellung. Gutamin und Gutamat wurden verwechselt.

**Developer response:** Leider ist das trotz intensiver Prüfung passiert. Wir bitten um Entschuldigung. Das 3.3 Update behebt diesen Fehler und fügt darüber hinaus neue Funktionen hinzu.

### 1/5 — Some information is wrong

*2024-03-11*

I have not checked all the information about the amino acids but I just saw under glutamine the structure of GLUTAMIC ACID. 
I found this to be highly unreliable and I consider it to be a waste of money.

**Developer response:** Unfortunately, this happened despite intensive examination. We apologize. The 3.3 update fixes this bug and also adds new features.

### 1/5 — Schlecht

*2014-01-29*

Kein Quiz vorhanden. Fehlkauf

### 3/5 — Für den Anfang ganz gut

*2013-10-25*

Ich fände eine noch Abfrage gut und eine Bildschirmanpassung fürs iPad, da ich zu Hause auf dem Sofa nicht mit dem iPhone sitzen, beziehungsweise auf einen angepassten Bildschirm des iPads schauen will. Wenn es das gibt vergebe ich auch gerne 5 Sterne :)

### 1/5 — Aus Wikipedia und dazu kostenpflichtig

*2013-05-30*

Ist die AS hydrophob oder hydrophil? Nicht mal einen Quiz zum Testen des Gelerntes... Nur bedingt zum Nachschlagen geeignet!

### 1/5 — Nett, aber...

*2012-05-18*

App gekauft, installiert und gestartet... Soweit in Ordnung, aber sobald ich in die Queransicht gehe und durch die Aminosäuren durchscrollen will stürzt die App ab, bei dem Preis (für so eine unkomplizierte App) ein "no go"!

Eine Karteikarten Funktion zum lernen der Strukturformeln wäre schön!

### 3/5 — Codons

*2010-11-24*

Search doesn't include stop codons or all codon combinations.

### 2/5 — "Chem Touch" offers more for only $0.99

*2010-08-02*

^^^ The layout here is more spacious than chem touch's but this doesn't include nucleic acids and detail on all elements of the periodic table. Had I realized the chem touch already provided the amino acid info, I never would have purchased this $3 app. Safe to say it is no longer on my touch.
