EVCalculator vs Nanoshel
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
EVCalculator
This app helps project managers quickly evaluate complex projects using earned value management. It generates a color-coded table with variances, indices, and forecasts, providing a narrative explanation of performance and potential data anomalies.
- Earned value data entry
- Color-coded performance table
- Variance and index calculations
- Forecasts at completion
- Rules-based narrative explanation
- Identifies data anomalies

EVCalculator is the perfect tool at a project management review to quickly evaluate performance on complex projects that use earned value management methodology. Enter the standard earned value data (BCWS, BCWP, ACWP, BAC and EAC), and EVCalculator instantly generates a color-coded table that includes all of the standard variances, indices and forecasts at completion, enabling you to quickly identify out-of-threshold items. These metrics are then processed by a sophisticated rules-based engine to provide an easily understood narrative that highlights and explains: 1) performance-to-date metrics; 2) disconnects between performance to date and forecasted performance; and 3) any data anomalies (i.e., ACWP > EAC) Generated metrics include: · % Scheduled · % Complete · % Spent · Cost Variance (CV) · Cost Variance % (CV %) · Cost Performance Index (CPI) · Schedule Variance (SV) · Schedule Variance % (SV %) · Schedule Performance Index (SPI) · Variance at Completion (VAC) · Variance at Completion % (VAC %) · To Complete Performance Index to Budget (TCPI-BAC) · To Complete Performance Index to Estimate to Completion (TCPI-EAC) · CPI Forecast at Completion · CPI*SPI Forecast at Completion · Weighted CPI + SPI Forecast at Completion · Performance Factor Forecast at Completion The program is compatible with the iPhone and iPad platforms and does not require an Internet connection once installed.

Nanoshel LLC is a Wilmington, Delaware based nanotechnology company specializing in the commercialization of wide range of Nanoparticles and innovative materials of 21st century. Nanoshel is revolutionizing nanomaterials where traditional materials fall short. Since 2005, Nanoshel has been exploring markets, developing innovative technologies, and providing breakthrough solutions using our Nanomaterials expertise. What’s interesting about materials on the Nano Scale – Contrary to popular belief is that size really does matter. That’s because when familiar materials are reduced to Nano proportions, they begin to develop odd properties. For example, plastics can conduct electricity, gold particles can appear red or green and solids can turn into liquids almost spontaneously at room temperature. While not all material is subject to change, the manipulation of such Nano change is a cornerstone of nanotechnology research. At the Nano scale, substances may behave differently or better compared to the same substances at macro sizes. For instance, Gold can change Colour, Carbon can conduct heat and electricity better Silver has improved antimicrobial properties. Other changes that occur to substances at the Nano scale can include: Becoming super-elastic, Becoming more chemically reactive, Getting physically stronger or weaker, and Being able to cope with massive changes in temperature and pressure. It’s because of these unique properties that nanotechnology could be used in such a huge range of products.

Verdict
The clearest difference is update cadence: Nanoshel at every 2 months against EVCalculator's every 9 months. EVCalculator's advantage is iOS requirement (9.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
