Gillmania
One thing at a time, done properly, by someone who needed it to exist.
Works out what size of hockey equipment fits a player. Enter the body measurements once and it gives the right size in every brand, because Bauer, CCM, Warrior, Sher-Wood and TRUE all measure differently.
Every number comes from the manufacturer's own published chart, with the source and the date it was verified.
Free on Google Play, and it runs in the browser too. The full size charts are readable here without installing anything.
Size charts and app →Hockey Gear is the first. Others are being built.
