the society, the amount of food resources (plant and animal) has increased, and thus, their wastes increase; therefore, the production of renewable fuels like biogas has increased. Biogas production and its quality are influenced by different slurry characteristics and biogas compounds, and their management is done using a computer with the help of complex algorithms, which are costly and require specialized training. For this purpose, a BioOptim application under the Android platform using Java programming language and 64-bit IDE was implemented with a high accuracy. For this purpose, some slurry characteristics and biogas compounds produced with co-digestion of different mixtures of citrous wastes and cow manure (0‒100%) pretreated with different amounts of NaOH and H₂O₂ (0‒3%) were studied. The measured parameters were modeled using multivariable regression models and used <a name="_Hlk38535681">to </a>imply in the BioOptim application. The evaluation results of the application showed that NRMSE of the parameters of C, N, C/N, Ca, TS, VS, K₂O, P₂O₅, pH, CH₄, CO₂, and CO was lower than 0.45. For these parameters, the statistical quantities of E_NS, d, R², and IR² were higher than 0.85, 0.95, 0.34, and 0.87, respectively. As found, the BioOptim application was only weak in determining parameter of H₂S and BOD. اپلیکیشن اندروید, ترکیبات بیوگاز, جاوا, مدلسازی, ویژگی های پیش مواد Android application, Biogas compounds, Java, Modeling, Substrate characteristics 47 61 http://necjournals.ir/browse.php?a_code=A-10-1086-2&slc_lang=fa&sid=1 Mahmood Mahmoodi-Eshkaftaki محمود محمودی اشکفتکی m.mahmoodi5@gmail.com 10031947532846006863 10031947532846006863 Yes Jahrom University دانشگاه جهرم Omid Omidi-Arjenaki امید امیدی ارجنکی omidmac@gmail.com 10031947532846006864 10031947532846006864 No Shahrekord University دانشگاه شهرکرد
