The I-STEM iOS application is the gateway for users to locate the specific facility(ties) they need for their R&D work and identify the one that is either located closest to them or available the soonest. Through a recent GoI directive, institutions with R&D facilities funded by agencies of the GoI are now required to list them on the I-STEM Portal. Through the I-STEM Portal or the web site of the organization where the desired facility is located, one can make a reservation for using it. To enable the running and maintenance of the resources, the organization may charge a fee, which depends on whether the user is from the academia, a public institution, or from industry. A panel of Experts will be formed over time to help users make the most informed use of resources available through I-STEM.

Verdict
The clearest difference is in-app purchases: I at none against Smart Science's 1. I also leads on iOS requirement (11.0 vs 13.0). Smart Science's advantage is update cadence (monthly vs every 10 months). On price, ads and device support there is nothing between them.
