iRecord App enables you to get involved with biological recording. Contribute your species sightings with GPS acquired coordinates, descriptions and other information, thus providing scientists with important new biodiversity information that contributes to nature conservation, planning, research and education. Your data will be kept secure and will be regularly backed up. Automatic checks will be applied to your observations to help spot potential errors, and experts can review your sightings. All wildlife sightings for non-sensitive species are shared with other users and will be made available to National Recording Schemes, Local Record Centres and Vice County Recorders (VCRs). โข Works fully offline โข Record all the wildlife you see - supports all UK species โข Add new records with minimal effort โข Benefit from automatic data checks and review by experts โข Share your sightings with the recording community โข Contribute to science and conservation
CodonQ

Evolution begins with the codon table. As Dr. Motoo Kimura, renowned for the neutral theory of molecular evolution, emphasized, memorizing the codon table is the essential first step in evolutionary biology, much like learning multiplication tables is foundational to mathematics. CodonQ is designed for students, researchers, and curious minds who seek to internalize the genetic code through engaging, self-guided quiz experiences. Whether you're just beginning or aiming to sharpen your recall speed, CodonQ offers an intuitive and flexible learning platform grounded in repetition and meaningful classification. CodonQ features two core quiz styles: Relaxed Quizzes, which group codons by amino acid chemical categories such as negatively charged, positively charged, polar, hydrophobic, and special, and Time-Constrained Quizzes, which challenge users to recall amino acid matches under time pressure. Users can also set a Custom Quiz Length to match their learning goals and study routine. Beyond quizzes, CodonQ supports the exploration of nonstandard codons and enables advanced peptide property analysis, making it valuable for both foundational learning and deeper sequence-function exploration. Users can tap any codon to instantly reveal its corresponding amino acid, along with key biochemical properties including polarity, charge, and hydrophobicity. Additionally, users can input short peptide sequences using the codon table, and the app calculates physicochemical properties of the resulting peptide helping bridge sequence with function. Whether in classrooms, research labs, or during personal study, CodonQ supports your evolutionary learning journey, one codon at a time.

Verdict
The clearest difference is in-app purchases: iRecord App at none against CodonQ's 1. iRecord App also leads on iOS requirement (15.0 vs 17.0). CodonQ's advantage is update cadence (every 9 days vs every 3 weeks). On price, ads and device support there is nothing between them.
