Tinkers’ Legacy on MCPEDL

If you liked Jenny Mod but want something with more freedom, I found this version really interesting — it works great with recent Minecraft updates too: fapcrafts.com/

I see there are so many comments about Jenny Mod xD

If you're experienced enough it's easy to download Jenny Mod, but this mod is updating only for PE now. I hope it will be ported to latest Java versions too :(

When I was really into Minecraft PE, I loved exploring add-ons to make the game more fun and unique. One of my favorites was this furniture mod that added all kinds of cool items like sofas, TVs, and even working fridges—made my builds feel so much cozier. Another one I tried recently was jennysmod.com. I came across it while looking for ways to customize my survival world, and it had some really creative features that spiced things up. Definitely worth checking out if you want something different!If you’re into survival challenges, I also recommend add-ons that tweak mobs or make resource gathering harder—it keeps things interesting.

Don't forget about communities with crossplay to Java Edition to get new material!

Hmmmm… might I recommend checking out MCPEDL? There’s also several free add-ons on the Marketplace (and many more if you wanna waste money on Minecoins lol)
