Limits, Fits and Tolerances Calculator (ISO System)
Both listings are pure in-app captures with no captions, so the standard reference decides it: "Tolerance and fits ISO" prints "TOLERANCE AND FIT ISO 286-1" on its first screenshot and shows an "ISO 286-1" / "ASME B4.1" toggle on the rest, matching the "iso 286" query on sight. "Fit Tolerance ISO" explains the fit best visually, with a colour hole/shaft schematic labelled "Interference" and "Clearance", but spends two of four slots on open dropdown lists over the same screen and never names a standard in any image. Neither listing carries a single outcome-oriented caption.
Scanned screenshots4 a · 4 b
Only the first 4 screenshots from each side are sent to the AI. These are what users see in App Store and Google Play search results, so they carry most of the conversion weight.

Value Proposition
A leads"Tolerance and fits ISO" heads screenshot 1 with "ISO 286-1" and a labelled rail: tolerance, fits, angle tolerances, roughness, casting tolerances.
"Fit Tolerance ISO" carries its promise only in the short description, "Limits, Fits and Tolerances Calculator (ISO System)"; no screenshot names a standard.
Clarity
TiedScreenshots 2 and 4 show input to output end to end: nominal 45, H7/g6, then a MAX/MIDDLE/MIN table with clearance in µm.
Screenshot 1's colour schematic draws hole against shaft with "Interference" and "Clearance" labelled; screenshot 2 states "Fit Type: Clearance Fit".
Emotional Hook
TiedAll four screenshots of "Tolerance and fits ISO" are bare calculator states; no caption band, no line about the machinist's job getting easier.
"Fit Tolerance ISO" ships raw device captures with the phone status bar and clock still visible; two slots are just open dropdown lists.
Trust Signals
A leadsThe "ISO 286-1" and "ASME B4.1" pills on screenshots 2 and 4 read as a visible conformance claim, though no downloads, reviews or endorsements appear.
"Fit Tolerance ISO" keeps its "ISO 286-1 (2010)" and "ANSI B4.2" citations in the description; only a small "References" tab hints at sourcing.
Reviewers of Tolerance and fits ISO repeatedly describe it as faster than physical charts and praise its interface, with one reviewer noting the Unity loading screen at startup as the only friction, too isolated to count as a recurring theme. Reviewers of Fit Tolerance ISO praise its usefulness and its parity with the web version, but a recurring thread asks about value coverage and accuracy, including limit values, mid-tolerance values and diameters above 3150 mm, plus a couple of mentions of ads. Both listings draw mostly short, positive engineering-workshop feedback.

LowTolerance and fits ISO positions itself as a multi-standard reference bench, opening on ГОСТ 25346, ISO-286, ГОСТ 25348 and ASME B 4.1 and adding GD&T, angle tolerances and dimensional chains. Fit Tolerance ISO positions itself as one calculator done thoroughly, naming ISO 286-1 (2010), ISO 286-2 (2010) and ANSI B4.2 and the parts it serves, from "journal bearings" to "cylinder bores". The mismatch is breadth-of-standards versus depth-on-one-job: a user searching "iso 286" sees one listing offering many reference tables and another stating exactly what it computes and draws.

Gap
Tolerance and fits ISO leads with coverage across standards families (ГОСТ, ISO-286, ASME B 4.1, ISO 1101) and tool count, while Fit Tolerance ISO leads with a single computation described end to end, including the fit classification and the drawn schematic.
Opportunity
Coverage across ГОСТ, ISO and ASME plus GD&T and dimensional chains is a scope no competitor on this keyword claims, so Tolerance and fits ISO can own the reader who works from drawings issued under more than one standard rather than competing as another fit calculator.
Risk
The title promises ISO while the description opens on ГОСТ 25346 and returns to ГОСТ 2.308, so an engineer searching "iso 286" may read the listing as a regionally-scoped reference and move on. The numbered feature index also states capabilities without stating an outcome, which makes the app harder to judge in the first three lines than a listing that says precisely what it calculates.
Strategic advantage
Cross-standard work is the buying motive: engineers checking a supplier print in ISO against an internal ГОСТ or ASME callout need one app that holds all three plus form and angle tolerances, and Fit Tolerance ISO's copy commits only to ISO 286 and ANSI B4.2.
Missed opportunity
Neither listing owns the moment of use at the machine or inspection bench, checking a drawing callout offline in seconds with no account or connection. Neither frames the result as inspection confidence, that a measured part conforms to the print, which is the reason the number is looked up at all.

Fit Tolerance ISO
Slight gap
Fit Tolerance ISO holds position 2 for iso 286 on a tighter single-job listing, yet Tolerance and fits ISO takes the overall head-to-head from position 3 on stronger reviewer sentiment and screenshots that name the standard on sight. The one-place gap looks like a relevance-signal gap, not a product gap.
Why it wins
Tolerance and fits ISO puts TOLERANCE AND FIT ISO 286-1 on its first screenshot and toggles ISO 286-1 against ASME B4.1 on the rest, so an iso 286 searcher confirms the match before reading a word, while Fit Tolerance ISO names no standard in any image. Its reviews also run cleaner: praise for speed against physical charts, against a recurring thread on Fit Tolerance ISO about value coverage, limit values and diameters above 3150 mm.
Biggest opportunity
Neither the title nor the short description of Tolerance and fits ISO carries the number itself, so rank 3 on iso 286 is currently earned by body copy alone, and moving the standard into the two fields the searcher actually reads is the cheapest lift available.
Next priority
Testing Tolerance and fits ISO 286 as the title, 26 characters, is the sharpest single move for iso 286, because the number is what the searcher scans the results list for. Pairing it with a short description that leads on the standard rather than ГОСТ 25346, such as ISO 286 fits, ГОСТ & ASME tolerances, GD&T, dimension chains at 60 characters, tests whether cross-standard breadth reads as coverage instead of regional scope.
