The HSvu-app (HighScore View) displays all kinds of X-ray diffraction scans in various formats. Additionally, it shows and reports all details from an X-ray diffraction analysis performed by the HighScore analysis software from PANalytical (proprietary .HPF format). Experience the power and ease-of-use of HighScore with HSvu: - use six different graphical views for references, single and multiple scans, quantifications and 3-dimensional graphs - pan and zoom-in for details like you do with HighScore - get a complete overview on measurement conditions, scans, peaks, profiles and crystal structure data - switch easily between graphics and textual information - unravel the parameters used in a diffraction analysis and its history - create reports covering either pieces or the complete diffraction document HSvu is a display or viewing app. It shows existing data, but it doesn't perform an analysis nor does it change data. The following file formats are supported: - PANalytical .HPF (proprietary HighScore document) - PANalytical scans ( .XRDML) - PANalytical ( .2Dint), ASCII format integrated from a 2D area detector - ASD Inc. binary spectrum ( .ASD) - Philips binary scans ( .RD), ( .SD), ( .FP), ASCCI ( .UDF), ASCII( .LIS) - Bruker binary scans ( .RAW) versions 1, 2, 3 and 4 - ASCII scans ( .LST), ( .UXD), ( .XDD) - Crystallographic information file: ( .CIF) - General ASCII scan X-Y(-Z) table ( .ASC) - DBW-Rietveld ASCII scan ( .RFL) - GSAS ASCII scans ( .RAW), ( .XRA) - ICDD PD3 ASCII scan ( .PD3) - JCAMP ASCII scan ( .JDX or .JCP) - LH-Rietveld ASCII scan ( .LHP) - MDI ASCII scan ( .MDI) - Rigaku ASCII scan ( .ASC), ( .FI),( .RAS), binary scan ( .RAW) - Scintag binary scan ( .RAW) - Seifert ASCII scan ( .ASC) - Shimadzu binary scan ( .RAW) - Skrowonek UDS2 ASCII scan ( .UDS) - Stoe CSD-PROFAN ASCII scan ( .PRO),( .DAT), binary scan ( .RAW) - Thermo Scientifique (ARL) scan ( .XML) - ASD Inc. binary spectrum (.ASD) Please note: - HSvu requires high processing power and a large memory. The data file size handled by HSvu is limited by the device capabilities and its performance. For a proper operation at least an A6 chipset, as present in the iPhone 5, is recommended. More recent devices with a 64-bit processor (like the A7 chipset) provide a very smooth user experience. - To compare several scans you must insert them into a document in HSvu.

Verdict
The clearest difference is rating: splotRF at 5.0 against HSvu's 3.0. splotRF also leads on update cadence (every 10 days vs every 9 months). HSvu's advantage is iOS requirement (11.0 vs 18.0). On price, ratings volume, ads and in-app purchases there is nothing between them.
