/Financial Calculators
Fair Price Calculator. A fair price calculator for dividend investors based based on your desired expected fair dividend value. Sample output: " Assuming a market size of 10000 millions $ if the market grows by 20% and the company's market share grows by 15% ( starting from a current market share of 8% ), with a gross margin of 30%, a net income being 10% of the gross profit, a payout ratio of 25% and a total of 100 millions shares, the expected dividend per share equals 0.08 $. Therefore, if your fair target dividend yield is 6% you should buy the stock at 1.38 $."
Net Return Calculator. It helps stock market investors to estimate their net profit from buying and selling stocks. Sample output: " If you invest now 10000 $ with an average annual dividend yield of 3 % in a stock paid 10 $ and sold at 12 $ kept 5 years considering taxes on dividends of 26 % and a capital gain taxes of 26 % , the average annual net return on investment is 5.18 % ( corresponding to a compound annual growth rate of 4.71 %), which increases your capital by 2590 $ to 12590 $. "
Sell Price Calculator. It helps you as asset owner or investor to determine the minimum price at which you should sell your assets to re-invest the new net capital in a different one. Sample output: " If you've already invested with an expected long-term average annual return of 5% taxed 26 % in an asset paid 10 $ and you want to re-invest your capital with a target return of 3% taxed 16 % , considering capital gain taxes of 26% you should sell your current asset at a price greater than 16.33 $ (being all other conditions the same). "
Bond's Net Return Calculator. A tool that helps investors to estimate the actual return they will receive from a bond investment from coupons and capital gain after accounting for taxes. Sample output: " If you invest now 10000 $ with a coupon rate of 3% in a bond paid at a face value of 100 and sold at 103 on 27 April 2027 considering income taxes of 26% and a capital gain taxes of 26% , the net final gain would be 887 $ (~2.87% CAGR) if you didn't miss any of the full annual payments, 832 $ (~2.69% CAGR) if you missed a quarter (25%) of the full annual payments, 776 $ (~2.52% CAGR) if you missed half (50%) of the full annual payments, 721 $ (~2.34% CAGR) if you missed 75% of the full annual payments.

/Diet App
Description. It calculates foods quantities you need to eat to satisfy your target conditions. You can add (or load from CSV) a custom set of foods. The app will let you define fats, carbs and proteins for each food and set your goals (calories percentages of protein, carbs or fats, total calories and minimum quantities). As a result the appropriate quantity (in grams) for each food is computed.
Target users. People who dont like to cook but buy ready-made food packages of different kind (e.g. frozen vegetables, legumes, eggs, ...). The problem of available free or commercial apps (untill now), is that some vendor-specific food is missing or not precisely addressed. Furthermore, direct quantity computation for given contraints is not always provided. Here, the user is free to enter grams of proteins, carbs and fats and set corresponding target conditions (energy percentages for proteins, carbs and fats or minimum quantities).
