## What is Resinly?

Resinly helps resin makers plan clean, repeatable pours with offline resin math, conversion help, and practical shop guidance.

Version 1.1 adds a Pro Pour Planner for larger and more demanding pours. Enter project size, depth, layer count, shop temperature, resin ratio, and working time to get a batch plan, Part A and Part B amounts, a heat-risk score, staged pour timing, and a finishing checklist.

Key features:
- Resin volume and mix planning
- Pro pour schedule with layer-by-layer timing
- Heat-risk guidance for thicker pours
- Part A and Part B mass estimates
- Offline checklist and shareable summary

Resinly is a practical maker utility. It does not require an account, subscription, analytics, or unnecessary network access.


## Version history (last 5 releases)

### 2.0.1 — 2026-06-26

This update sharpens the interface: the iPad layout now uses a centered, comfortable reading width instead of stretching edge to edge, plus small display fixes. iPhone is unchanged.

### 2.0 — 2026-06-21

Resinly 2.0 — a pro upgrade for resin casters, still 100% offline.

• Exotherm heat model: estimated peak core temperature, a critical / watch / controlled verdict, and your max safe batch size.
• Temperature-adjusted cure timeline: tack-free, demold, light-use, and full-cure milestones shifted for your room temperature (and flagged if it's too cold to cure).
• Seal-coat & porosity estimator for live-edge wood and porous moulds.
• Off-ratio checker: exactly how far off your measured A:B is, the direction, and your safe measuring slack.
• Heat-safe cup splitter: the fewest equal cups to keep each batch under the heat ceiling, in pour order.

No account, no network — every calculation stays on your device.

### 1.3 — 2026-06-20

Introducing Coverage — the inverse solver: tell Resinly how much resin you have and it finds the depth you'll reach, the area you can cover, and your mould headroom, with the exact A/B mix split. Plus per-part cost breakdowns, a shareable result, and a full accessibility pass.

### 1.2 — 2026-06-15

Resinly 1.2

New: Pigment & Colorant Calculator tab. Tell the app how much resin you have and choose your colorant type (mica powder, pigment paste, alcohol ink, or oxide pigment) and desired opacity, and Resinly shows the exact grams to add — plus a warning before you hit the 4% cure-risk limit. Includes a multi-colour split tool for dividing one batch into up to 8 tinted portions.

New: Cure notes on saved projects. Swipe right on any project to add freeform notes — temperature, humidity, brand used, what went right or wrong. Notes appear under the project name as a quick reminder for next time.

New: Temperature working-window guidance in Pro Pour. The planner now shows how your room temperature affects effective pot life, using the Rule of 10 (reaction rate roughly doubles per +10 °C rise). Colour-coded zones (ideal / warm / hot / cold) so you know when to split batches smaller before you start.

### 1.1 — 2026-06-12

Resinly 1.1 adds Pro Pour Planner.

- New batch schedule for splitting large pours into safer, repeatable stages.
- Per-pour Part A / Part B mass guidance using the existing Resinly ratio engine.
- Heat-risk score based on batch size, depth, pot life, and room temperature.
- Bench checklist and shareable pour plan for shop notes.
