About WillItSnap — The Phone Accessory Compatibility Database
By WillItSnap Team · March 15, 2026
WillItSnap is a free phone accessory compatibility database. We help you figure out whether your old case, screen protector, charger, or other accessories will work with a new phone — before you waste money finding out the hard way.
What Is WillItSnap?
WillItSnap is a phone accessory compatibility checker built on a database of 171 phone models across 13 brands. Pick any two phones and we instantly tell you whether a case from one will fit the other, backed by a detailed score and plain-English explanation.
Beyond case compatibility, we also cover screen protectors, MagSafe and Qi2 wireless charging, wired charger compatibility, car mount sizing, and side-by-side size comparisons. Everything is powered by official manufacturer dimension data — not user opinions or guesswork.
What We Cover
Case Compatibility
Our core feature. We check whether a case designed for Phone A will fit Phone B by analyzing dimensions, camera layout, button positions, and port type. Currently 7,516 phone pairs pre-computed.
Screen Protector Compatibility
Screen protectors depend on screen size, bezel width, and front-face curvature. We check whether a protector from one phone will cover the display of another.
MagSafe & Qi2 Compatibility
Not all phones support MagSafe or Qi2. We track which phones have magnetic wireless charging, standard Qi, or no wireless charging at all.
Charger Guides
USB-C vs Lightning, wattage requirements, fast charge standards — we break down exactly which chargers work with which phones.
Car Mount Fit
Will your phone fit in a standard car mount? We categorize phones by size and weight and recommend mount types based on dimensions.
Size Comparisons
Side-by-side dimension comparisons for any two phones. Height, width, thickness, weight, screen size, and camera bump measurements in one view.
All features cover 171 phones across 13 brands, updated regularly as new models are announced.
Why WillItSnap Exists
Buying a new phone should not mean guessing which of your old accessories still work. Yet that is exactly what most people do — they search Reddit, read conflicting Amazon reviews, or just hope for the best. And more often than not, they end up with a case that does not fit or a charger that does not fast-charge.
WillItSnap exists to replace guesswork with data. Every compatibility result is computed from the same set of verified manufacturer specifications, so the answer is consistent, transparent, and available in under a second.
We believe that a $15 phone case purchase should not require 30 minutes of research. Pick two phones, get a score, and move on with your day.
Our Data Accuracy
- All dimensions from official manufacturer specs. We source height, width, thickness, camera bump measurements, and button positions directly from Apple, Samsung, Google, and other OEM specification pages. We never rely on third-party estimates or user-submitted data.
- Scoring algorithm verified against real-world case fit testing. Our seven-factor compatibility algorithm was calibrated against known fit/no-fit pairs and produces results that match real-world outcomes. The thresholds (0.5mm width, 1mm height, camera layout match) are grounded in how phone cases are actually manufactured.
- Regular updates when new phones launch. We add new phone models within days of their official announcement. When manufacturers revise specifications after launch, we update our records accordingly.
- Transparent methodology. Our methodology page explains exactly how the scoring algorithm works, in plain English. No black boxes.
